Opportunity Mapping of the E-Health Sector prior to COVID19 Outbreak

Authors: Akad Doha, Markman Ofer and Lefkort Jared

 

This paper investigates 30 deals in the fields of digital health and e-health from 2017-2020, specifically observing deal size and other critical information.

Variables:

Target audience – the target audience of the deal purpose

Year – the year in which the deal was conducted

Deal size – deal size in million $USD

Deal business rationale

Platform type

Service type

Deal prioritization

Market

Field

Descriptive Statistics and General Characteristics:

Deals in the field of digital and e-health were targeted towards six groups. This includes patients, {general}, organizations, employees, aging in place, and students. The majority of deals were focused on patients, as is seen in figure 1.

 

Figure 1: Tech Company Deals Organized by Target Population

 

Figure 2: Size of Tech Company Deals from 2017-2019, Organized by Target Population

Figure 2 depicts the size of deals in the digital and e-health fields in $USD between 2017-2019, targeting different populations. Those deals targeting the “general” population, and those targeting patients were observed to have the largest size. In particular, deals focused on patients were found to be significantly larger in 2018 when compared to patient-focused deals in 2017 and 2019.

Figure 3: Size and Specific Market of Digital and E-Health Deals by Target Population

Figure 3 shows that in the technology market, the greatest deal size is observed when targeted towards the general population, or patients. On the other hand, deals in the health services market tend to have the greatest size when targeted towards general customers, employees, and patients.

Figure 4: Rationale for Deals in the Tech Industry

Figure 5: Deal Sizes based on Business Rationale

Deals that introduce a new service for a company represent the largest deals. It is also important to note that deals focused on digital solutions and improvements to existing services were fairly large in size. When examining the relationship between deal size and business rationale, we can see that the largest and majority of deals were focused on company independence, acquiring information, market expansion, the addition of a new service or product, and the expansion of saas (software as a service).

This information has led to the analysis that there is a relationship between business rationale deal size.

 

Figure 6: Number of Deals by Platform Usage

 

While substantial platform usage information was not available for all companies, for those that had data, app and cloud platforms tended to be the dominant platform.

 

Figure 7: Number of Deals by Target Experience Improvement

 

 

 

 

Figure 8: Deal Size by Target Experience Improvement

 

Customer and patient experience where the main interest of deals in 2017 and 2018.

Figure 8 shows that customer and patient experience categories account for the largest deal sizes.

 

Figure 9: Number of Deals by Market Sector

 

Figure 10: Deal Size by Market

Figure 9 depicts the fact that most deals occurred in the health services, technology and analytics markets from 2017 to 2019. Figure 10 shows that clinical, research, and shopping markets have the three largest average deal sizes. Thus, the market in which the deal occurs plays a major role in the size of each deal.

Figure 11: Number of Deals by Field

 

Figure 12: Deal Size by Field

 

The majority of deals observed occurred in the fields of healthcare and internet-based media. The field of the deal is one of the four main contributors to the size of a deal.

If we look at the deal size specified by field, we can see that diabetes care, wearables, life sciences and oncology care have the largest sizes.

 

Figure 13: Average Deal Size ($USD) by Year (2017-2019)

Deals observed in 2018 had the largest size in terms of $USD when compared to those occurring in 2017 and 2019. However, the largest single deal took place in 2019.

Inferential Statistics:

As depicted in the above section, the main factors that affect the size of a deal are the market, business rationale, improvements in targeted user experience, and field of the deal.

A clustering analysis has been performed for years between 2017-2019.

 

Figure 14: Cluster Analysis of Deal Size by Year (2017-2019)

Three different groups were identified through the cluster analysis:

  • Cluster 1 (Red): deals in 2019 and 2018 sizes less than or equal to 1 billion.
  • Cluster 2 (Green): deals between 2017-2019 with sizes of approximately 2 billion or greater.
  • Cluster 3 (Blue): deals in 2017 under 500 million.

 

Figure 15: Cluster Analysis of Deal Size by Market Sector

 

Figure 15 shows that cluster 2 deals (green) in the clinical, health services, and research markets are all sized at approximately 2 billion and greater.

This trend continues amongst the other clusters, as cluster 3 deals (blue) remain at a size of less than half a billion in the health services and analytics markets, and cluster 3 deals (blue) remain at a size of 1 billion or less.

Thus, in general, all markets offer approximately 1 billion and under deals with higher deals only available in clinical, health services, and research markets.

 

Figure 16: Cluster Analysis of Deal Size by Field

 

Figure 16 shows that the cluster 2 deals (2 billion in size) mainly occur in the fields of diabetes care, health wearables, internet-based media, life sciences and oncology care.

There are deals in all fields that are approximately 1 billion and under.

Cheaper deals in blue (below half a billion) are only in healthcare and smartwatches.

 

Figure 17: Cluster Analysis of Deal Size by Business Rationale

Business Rationale: Deals aiming to add new services, increasing company independence and acquiring wider information show deal sizes of approximately 2 billion and above. It is noteworthy that deals whose rationale is to integrate more clients, more experts and provider groups, and analytical solutions are clearly under 0.5 billion $USD.

 

Figure 18: Cluster Analysis of Deal Size by Deal Prioritization

From figure 18 one can observe that deals with higher deal prices tend to focus on customer and patient experience.

Other categories are mixed and do not depict a trend when it comes to the price of deals. However, we can see that most of the cluster 3 deals focus on patient experience.

 

Conclusion:

More Comments, conclusions:

Deals approximately 2 billion and above are featured with:

  1. clinical, health services & research markets
  2. diabetes care, health wearables, internet-based media, life science and oncology care fields
  3. business rationale: adding new services, company independence and acquiring wider information.
  4. Are interested in customer and patient experience.

Deals approximately 1 billion and below are featured with:

  1. in 2018-2019
  2. Analytical, delivery, digital, electronic solutions, expand capability, expand globally, improvement, inelegant platforms and more client’s

Deals under 0.5 billion are featured with:

  1. In 2017 only
  2. Deal offers integrating more clients, more experts and provider groups and analytical solutions.
  3. Patient and employee experience.

 

End Notes

Statistical Methods: Since we are interested in the features of deals in the tech industry between 2017-2019, before doing the clustering several multi-linear models was conducted to decide which model include the best variables to explain deal size looking at different significant measures mainly AIC (r-squared, adj-r and so on).

Additional Clustering Information: in figure 16, Although healthcare exists in all clusters, because of other specific descriptions of the field we still can say that the clusters contributes to the understanding of what fields are best to wrap up a deal.

CRISPR-Cas9 and the Power of Butterfly Gene Editing

Reporter: Madison Davis

Genome editing is a relatively new branch of genetic engineering that utilizes modern technologies in altering, inserting, or deleting selective DNA sequences within cells.  CRISPR-Cas9, otherwise known as “Clustered Regularly Interspaced Short Palindromic Repeat”, is a groundbreaking genome editing technique for scientists, as it is more efficient and allows for more precise genome changes at less of a cost in comparison to other editing methods.  The CRISPR-Cas9 procedure chiefly involves two biological molecules: an enzyme known as “Cas9” whose role is to cut the DNA during transcription, and a guide RNA molecule located within the Cas9 enzyme.  

The process of extracting and editing certain segments of DNA begins with identifying the respective segment of DNA to edit, typically around twenty nucleotides in length but can vary depending on the goal of the scientists.  This selection process can be based on prior knowledge of gene mapping sequences or random experimentation.  Upon identifying the segment, scientists will manually formulate a guide RNA molecule that matches the sequence of nucleotides found in the DNA sequence.  This gRNA molecule will then be placed in empty Cas9 enzymes.  Through the process of transcription, Cas9 enzymes will find and cut out the designated DNA sequence, where scientists are then able to insert, delete, or modify certain sequences by hand under high-definition microscopes.  

The usage of CRISPR can range from identifying tumor suppressor genes to gene mapping for species.  In recent years, it has been used more specifically to understand the evolutionary genetics behind butterfly wing patterns.  Butterfly wings are constructed from two separate layers that contain thousands of individual scales made of a hard protein called chitin.  Each individual scale contains embedded structures and pigments that reflect or absorb certain colors of light depending on their wavelengths.  Their unique structures allows certain butterfly species to exhibit wide ranges of color variation.  All together, these scales can act as identification, insulation, and camouflage. 

Through selective processing, scientists were able to identify how a loss in a certain genetic sequence labeled WntA results in a reduction in CSS (Central Symmetry Systems) and pattern boundaries, resulting in more abstract wing patterns.  A research expedition led by Anyi Mazo-Vargas experimented on two species, Heliconius erato demophoon and Heliconius sara sara.  Each butterfly wing pair composed of mainly black pigment with two main stripe patterns consisting of red and yellow and blue and white for each species, respectively.  When the WntA gene was removed in offspring, there was an increase in color pigment in areas that were previously black scales.   For instance, in Heliconius erato demophoon, there appeared to be more blurred red and yellow pigment rather than distinct colored stripe patterns.  The WntA gene was also experimented in monarch butterflies, where an absence in WnTA genes caused the initially black tipped-scales of the monarch wings to become a whiter, “bleached” pigment.

While efficient in scale, CRISPR-Cas9 editing system is often riddled with mosaic mutations, which can be a challenge in making valid conclusions in gene editing.  Mosaicism is a process of gene editing that results in an individual having multiple cells with different DNA sequences.  Not all cells of a singular individual contain the same genetic code.  When editing genetic sequences during the larva stage, not all subsequent cells are affected by such a change, and thus changes in butterfly wings can only be partially identified.  As CRISPR and other gene editing technologies continue to evolve, scientists should try to increase the accuracy of their experiments, such as editing genes in earlier germline cells or varying their experiments on more subspecies for more data analysis.

Medical Device Technology for Alzheimer’s Diseases

Reporter: Danielle Smolyar

 

Alzheimer’s disease is said to be caused by a large number of proteins that are overproduced around a brain cell. Alzheimer’s is an irreversible disease that overtime decreases a person’s memory and the ability to perform tasks. With this disease, it is hard to function day to day life because it is hard to take on simple daily tasks or activities. It is a powerful and advanced disease that has not yet been found a cure. There have been many trials and scientists and researchers are still trying to figure out and find a cure for this disease because so many people, unfortunately, suffer from it.

This acute disease has no cure yet.  In an article titled, World Alzheimer’s Month: Exploring the latest research and devices for early detection, According to the Alzheimer’s Association,

“an estimated 5.3 million Americans are currently living with Alzheimer’s disease. By 2025, that number is expected to increase to more than seven million. Doctors diagnose dementia in around 10 million people every year, and 60–70% of these new diagnoses detect Alzheimer’s disease.”

The reality of the disease is tragic and the fact that the numbers keep growing calls for more urgency to find a cure and help innocent people fight off this disease. With society’s new technological and medical advancements, researchers have been working on finding a cure or developing a medical device to help people with Alzheimer’s. The article also states, ”Dr. Thom Wilcockson, from the UK’s Loughborough University, found that

eye-tracking technology could help identify mild cognitive impairment (MCI) in patients who might go on to develop Alzheimer’s disease in the future.”

With this technology and how advanced our society is, technology could eventually find a cure. With this device, it can help and make a considerable change in the number of people who develop Alzheimer’s. This new tool could help people prepare for the sickness or prevent future conditions from getting worse. Ultimately, if we have this technology, it can teach the world and educate the world on this condition and how we can take strides into preventing it from happening.

Dr. Thom Wilcosckon stated that looking for MCI can be a benchmark or sign for doctors to look for early development of Alzheimer’s:

Dr. Wilcockson and the research team worked with 42 patients with a diagnosis of aMCI, 47 with a diagnosis of naMCI, 68 people with dementia caused due to Alzheimer’s disease, and 92 healthy controls as part of their study. During the study, the participants were instructed to complete antisaccade tasks that are simple computer test where participants are told to look away from a distractor stimulus. The researchers found that they were able to differentiate between the two forms of MCI by looking at the eye-tracking results.

This modern technique of being able to pinpoint a specific aspect that would differentiate patients and their sicknesses from one another can cause a massive shift in the Alzheimer’s world. One step at a time, doctors, scientists, and researches are learning more about Alzheimers and are inching closer to hopefully finding a cure in the near future.

A sweet perspective on the COVID-19 pandemic – glycobiologist view on the effort to curb the pandemic

Author: Dr. Ofer Markman

AN EXPERT OPINION

A sweet perspective on the COVID-19 pandemic – glycobiologist view on the effort to curb the pandemic.

The sugars involved in a viral disease are unique in many ways when compared with the DNA/RNA or the proteins involved: they are almost totally dependent on the infected cells and tus are not affected by the viral mutation rate or by the virus at all. Nevertheless they are affected by the cells, their type and their sugar production mechanisms and in some respect to the production rate by which the virus in manufactured by the infected cells. Mutations may have neverthless major effect not on the structures of the glycans but rather on the axsistance of the glycosylation site, and thus the glycan at all, but not on its structures.

This may make the gycomolecule a good target for diagnostics as stability in the molecule may mean longer life time of the diagnostic kits.

Unique sugars are already predicted/found in the virus from certain chinese origin, in this case an o-linked glycan/s not previously detected.

https://www.tandfonline.com/doi/full/10.1080/22221751.2020.1739565

Nevertheless, if the virus can infect multiple cells once current cells are not going to be available for any reason those viruses may present other glycans.

Once one starts to treat the infected person via modulation of protein production or by other means the change in the dynamic of protein production vs. protein glycosylation may cause changes in protein glycosyation, including their structures, this is well known to biotechnologists producing glycoproteins in labs and production.

This may either be a problem in understanding the state of disease or an advantage as it may help following response to the treatment and help as a co-treament diagnostics.

For that purpose we are starting to see pioneering players in that regard:

https://www.technologynetworks.com/diagnostics/news/carbohydrate-based-diagnostics-a-new-approach-to-covid-19-testing-332313

Glycans may play a role in treatment as well, TAMIFLU is uch an example. Tamiflu is directed to the flu enzyme Neuraminidaze that is part of the viral structures. This approch was also explored to develop treatments.

https://www.pharmasalmanac.com/articles/pneumagen-ltd-leverages-its-novel-glycan-approach-to-target-coronavirus-covid-19-infections

but glycans do not only effect their own involvement in treatment/diagnostics they also are effecting protein based diagnostics for this see statement by Dr. Michael Mercier of UAH

Recent Grim COVID-19 Statistics in U.S. and Explanation from Dr. John Campbell: Why We Need to be More Proactive

Reporter: Stephen J. Williams, Ph.D.

In case you have not been following the excellent daily YouTube sessions on COVID-19 by Dr. John Campbell I am posting his latest video on how grim the statistics have become and the importance of using proactive measures (like consistent use of facial masks, proper social distancing) instead of relying on reactive measures (e.g. lockdowns after infection spikes).  In addition, below the video are some notes from his presentation and some links to sites discussed within the video.

 

Notes from the video:

  • approaching 5 million confirmed cases in US however is probably an underestimation
  • 160,00 deaths as of 8/08/2020

From the University of Washington Institute for Health Metrics and Evaluation in Seattle WA

  • 295,000 US COVID-19 related deaths estimated by December 1, 2020
  • however if 95% of people in US consistently and properly wear masks could save 66,000 lives
  • however this will mean a remaining 228,271 deaths which is a depressing statistic
  • Dr. John Campbell agrees with Dr. Christopher Murray, director of the Institute for Health Metrics that “people’s inconsistent use of these measures (face masks, social distancing) is a serious problem”
  • States with increasing transmission like Colorado, Idaho, Kansas, Kentucky, Mississippi, Missouri, Ohio, Oklahoma, Oregon, and Virginia are suggested to have a lockdown when death rate reaches 8 deaths per million population however it seems we should be also focusing on population densities rather than geographic states
  • Dr. Campbell and Dr. Murray stress more proactive measures than reactive ones like lockdowns
  • if mask usage were to increase to 95% usage reimposition to shutdown could be delayed 6 to 8 weeks

 

New IHME COVID-19 Forecasts See Nearly 300,000 Deaths by December 1

SEATTLE (August 6, 2020) – America’s COVID-19 death toll is expected to reach nearly 300,000 by December 1; however, consistent mask-wearing beginning today could save about 70,000 lives, according to new data from the Institute for Health Metrics and Evaluation (IHME) at the University of Washington’s School of Medicine.The US forecast totals 295,011 deaths by December. As of today, when, thus far, 158,000 have died, IHME is projecting approximately 137,000 more deaths. However, starting today, if 95% of the people in the US were to wear masks when leaving their homes, that total number would decrease to 228,271 deaths, a drop of 49%. And more than 66,000 lives would be saved.Masks and other protective measures against transmission of the virus are essential to staying COVID-free, but people’s inconsistent use of those measures is a serious problem, said IHME Director Dr. Christopher Murray.

“We’re seeing a rollercoaster in the United States,” Murray said. “It appears that people are wearing masks and socially distancing more frequently as infections increase, then after a while as infections drop, people let their guard down and stop taking these measures to protect themselves and others – which, of course, leads to more infections. And the potentially deadly cycle starts over again.”

Murray noted that there appear to be fewer transmissions of the virus in Arizona, California, Florida, and Texas, but deaths are rising and will continue to rise for the next week or two. The drop in infections appears to be driven by the combination of local mandates for mask use, bar and restaurant closures, and more responsible behavior by the public.

“The public’s behavior had a direct correlation to the transmission of the virus and, in turn, the numbers of deaths,” Murray said. “Such efforts to act more cautiously and responsibly will be an important aspect of COVID-19 forecasting and the up-and-down patterns in individual states throughout the coming months and into next year.”

Murray said that based on cases, hospitalizations, and deaths, several states are seeing increases in the transmission of COVID-19, including Colorado, Idaho, Kansas, Kentucky, Mississippi, Missouri, Ohio, Oklahoma, Oregon, and Virginia.

“These states may experience increasing cases for several weeks and then may see a response toward more responsible behavior,” Murray said.

In addition, since July 15, several states have added mask mandates. IHME’s statistical analysis suggests that mandates with no penalties increase mask wearing by 8 percentage points. But mandates with penalties increase mask wearing by 15 percentage points.

“These efforts, along with media coverage and public information efforts by state and local health agencies and others, have led to an increase in the US rate of mask wearing by about 5 percentage points since mid-July,” Murray said. Mask-wearing increases have been larger in states with larger epidemics, he said.

IHME’s model assumes that states will reimpose a series of mandates, including non-essential business closures and stay-at-home orders, when the daily death rate reaches 8 per million. This threshold is based on data regarding when states and/or communities imposed mandates in March and April, and implies that many states will have to reimpose mandates.

As a result, the model suggests which states will need to reimpose mandates and when:

  • August – Arizona, Florida, Mississippi, and South Carolina
  • September – Georgia and Texas
  • October – Colorado, Kansas, Louisiana, Missouri, Nevada, North Carolina, and Oregon.

Contagious

We are in the midst of a pandemic that is impacting people and society in ways that are hard to grasp. The most apparent impact is on physical health. It also effects our attitudes in society, our economy and our cultural life. Throughout history, humanity has had to face the challenge of understanding, managing and fighting viruses.

In the exhibition Contagious we are highlighting Nobel Prize-awarded researchers who have expanded our knowledge about viruses, mapped our immune system and developed vaccines. We also examine the perspectives from Literature and Economics Laureates about the impact of epidemics on life and society. Visit us at the museum or on these pages.

Museums have an important role to play in times of crisis, since they can help people tackle existential questions and provide a broader context. The Nobel Museum is about ideas that have changed the world. The Nobel Prize points to the ability of humans to find solutions to difficult challenges that we face time and time again. It is a source of hope, even in the midst of the crisis.

Coronavirus

On March 11 this year, the World Health Organization announced that the spread of the coronavirus should be classified as a pandemic, that is “an infectious disease that spreads to large parts of the world and affects a large proportion of the population of each country”. Today, nobody knows how many will die in this pandemic, or when, or if, we can have a vaccine against the disease.

SARS-CoV-2, or Severe acute respiratory syndrome coronavirus 2, is an RNA virus from the family coronavirus that causes the respiratory disease covid-19.

The virus was detected at the end of last year in the Wuhan sub-province of China, and in most cases causes milder disease symptoms that disappear within two weeks. But sometimes, especially in certain groups such as the elderly and people with certain other underlying illnesses, the infection becomes more severe and can in some cases lead to death.

The virus is believed to have zoonotic origin, that is, it has been transmitted to humans from another animal. Where the origin of the disease comes from, that is to say from which host animal the virus originates, is still unknown. However, the virus has close genetic similarity to a corona virus carried by some bats, which might indicate where the virus comes from.

This model shows the SARS-CoV-2 virus, which causes the illness covid-19. The globe-shaped envelope has a membrane of fat-like substances. Inside the envelope are proteins bound to RNA molecules, that contain the virus’s genes. Short spikes of proteins and longer spikes of glycoprotein stick out of the envelope and attach to receptors on the surface of attacked cells. The spikes, which are bigger at the top, give the virus its appearance reminiscent of the Sun’s corona. This where the coronavirus’s name comes from.

Testing is an important tool for tracking and preventing the spread of infection during an epidemic.

One type of test looks at if a person is infected by looking for traces of the virus’s RNA genetic material. The test is taken using a swab stick inserted into the throat. The small amounts of RNA or DNA that attach to the swab are analyzed using the PCR technique, which was invented by Kary Mullis in 1983. Ten years later he was awarded the Nobel Prize in Chemistry.

Another type of test looks for antibodies to the virus in the blood. This indicates that the person has had the disease.

The first virus ever discovered

We have understood since the 19th century that many diseases are caused by microscopic bacteria that cannot be seen by the naked eye. It turned out that there were even smaller contagions: viruses. Research on viruses has been recognized with several Nobel Prizes.

Spanish flu

The worst pandemic of the 20th century was the Spanish flu, which swept across the world 1918–1920.

The Spanish flu was caused by an influenza virus. American soldiers at military facilities at the end of World War I were likely an important source of its spread in Europe. The war had just ended, and the pandemic claimed even more lives than the war. Between 50 and 100 million people died in the pandemic.

The Red Cross, an international aid organization, which received the Nobel Peace Prize for its efforts during the war, also took part in fighting the Spanish flu. International Committee of the Red Cross received the prize in 1917, 1944 and 1963.

This photo shows personnel from the Red Cross providing transportation for people suffering from the Spanish flu in St. Louis, Missouri in the United States.

Polio

Polio is an illness that often affects children and young people and that can lead to permanent paralysis.

Polio is a highly infectious RNA virus belonging to the genus Enterovirus. The virus only infects humans and enters the body via droplets such as sneezing and coughing, or through contact with infected people’s feces. Usually, polio infects our respiratory and intestinal tract, but sometimes the virus spreads to the spinal cord and can then cause paralysis. The virus mainly affects children, but most of those infected show no or very mild symptoms.

Vaccines are a way to help our immune system fight viruses. The immune system is the body’s defence mechanism against attacks from viruses and bacteria. A number of Nobel Laureates have researched the immune system and contributed to the development of vaccines.

Hepatitis B

The virus can infect people without them becoming sick. Discoveries in the 1960s enabled both vaccines and tests to prevent the spread.

Hepatitis B can infect humans and apes, and is most common in West Africa and in sub-Saharan Africa. The disease also occurs in the rest of Africa, as well as in areas from the Caspian Sea through to China and Korea and further down to Southeast Asia.

Baruch Blumberg discovered the virus behind hepatitis B and developed a vaccine against the disease.

There are many varieties of hepatitis, or jaundice, that cause inflammation in the liver. When studying blood proteins from people from different parts of the world at the end of the 1960s, Baruch Blumberg unexpectedly discovered an infectious agent for hepatitis B. He showed that the infectious agent was linked to a virus of previously unknown type. The virus can infect people without them becoming sick. The discoveries enabled both vaccines and tests to prevent the spread through blood transfusions.

Baruch Blumberg was awarded the Nobel Prize in Physiology or Medicine 1976. He has summarized what the Nobel Prize meant to him.

Yellow fever

Each year, Yellow fever causes about 30,000 deaths. The vaccine against yellow fever was produced in the 1930s. A work awarded the Nobel Prize.

Yellow fever is a serious disease caused by a virus that is spread by mosquitos in tropical areas of Africa and South America.

Each year, Yellow fever causes about 200,000 infections and 30,000 deaths. About 90% of the cases occur in Africa. The disease is common in warm, tropical climates such as South America and Africa, but it is not found in Asia.

You may think that the number of people infected would be decreasing, but since the 1980s the number of yellow fever cases has unfortunately increased. This is believed to be due to the fact that more and more people are living in cities, that we are traveling more than before, and an increased climate impact.

Since there is no cure for the disease, preventive vaccination is a very important measure. Max Theiler successfully infected mice with a virus in the 1930s, which opened the door to more in-depth studies. When the virus was transferred between mice, a weakened form of the virus was created that gave monkeys immunity. In 1937, Theiler was able to develop an even weaker version of the virus. This version could be used as a vaccine for people.

Max Theiler was awarded the Nobel Prize in Physiology or Medicine in 1951.

HIV/AIDS

In the early 1980s, reports began to emerge about young men that suffered from unusual infections and cancers that normally only affect patients with weakened immune systems. It turned out to be a previously unknown epidemic, HIV, which spread rapidly across the world.

HIV, which is an abbreviation of human immunodeficiency virus, is a sexually transmitted retrovirus that attacks our immune system. An untreated infection eventually leads to AIDS, or acquired immune deficiency syndrome. In 2008, French scientists Luc Montagnier and Françoise Barré-Sinoussi were awarded the Nobel Prize in Physiology or Medicine for the detection of human immunodeficiency virus.

Watch the interview where Françoise Barré-Sinoussi talks about what it is like to meet patients affected by the virus she discovered.

Viruses captured in photos

Viruses are incredibly small and cannot be seen in normal microscopes.

The electron microscope, which was invented by Ernst Ruska and Max Knoll in 1933, made it possible to take pictures of much smaller objects than was previously possible. Ernst Ruska’s brother, Helmut Ruska, was a doctor and biologist, and used early electron microscopes to make images of viruses and other small objects. The tobacco mosaic virus was the first virus captured on film. The development of the electron microscope has enabled increasingly better images to be taken.

Ernst Ruska was awarded the 1986 Nobel Prize in Physics together with Gerd Binnig and Heinrich Röhrer, who developed the scanning electron microscope.

Epidemics and literature

When epidemics and pandemics strike the world, it isn’t just the physical health of people that are impacted but also ways of life, thoughts and feelings. Nobel Laureates in literature have been effected by epidemics and written about life under real and fictive epidemics.

The coronavirus crisis has had a dramatic impact on our lives and our view of our lives. Olga Tokarczuk is one of the authors who has reflected on this.

Tokarczuk argues that the coronavirus has swept away the illusion that we are the masters of creation and that we can do anything since the world belongs to us. She wonders if the pandemic has forced us into a slower, more natural rhythm in life, but also worries about how it may increase distrust of strangers and worsen inequality among people.

Orhan Pamuk has worked for many years on a novel about a bubonic plague epidemic that struck primarily Asia in 1901. The coronavirus crisis has caused him to consider the similarities between the ongoing pandemic and past epidemics throughout history.

He sees several recurring behaviors when epidemics strike: denial and false information, distrust of individuals belonging to other groups, and theories about a malicious intent behind the pandemic. But epidemics also remind us that we are not alone and allow us to rediscover a sense of solidarity. He writes in The New York Times.

Economics Laureates on the current pandemic

Pandemics have wide-ranging impacts on the economy. Paul Romer and Paul Krugman are two economists who have been active in the public discourse during the coronavirus crisis.

Paul Romer has expressed concerns about the pandemic’s effects on the economy but is optimistic about the possibilities of technology. He supports widespread testing. Those who are infected have to stay home for two weeks while others can work and take part in other ways in society.

Paul Romer was awarded the prize “for integrating technological innovations into long-run macroeconomic analysis.” Paul Romer has demonstrated how knowledge can function as a driver of long-term economic growth. He showed how economic forces govern the willingness of firms to produce new ideas.

His thoughts are developed in his lecture during the Nobel Week 2018.
