Michael Levitt Analysis: Corona Is Slowing Down, Humanity Will Survive.

Nobel laureate and Stanford professor of Biology assures Israelis: statistics show the virus is on a downturn.


Nobel laureate Michael Levitt, an American-British-Israeli biophysicist who teaches structural biology at Stanford University and spends much of his time in Tel Aviv, unexpectedly became a household name in China, offering the public reassurance during the peak of the country’s coronavirus (Covid-19) outbreak. Levitt did not discover a treatment or a cure, just did what he does best: crunched the numbers. The statistics led him to the conclusion that, contrary to the grim forecasts being branded about, the spread of the virus will come to a halt.


The calming messages Levitt sent to his friends in China were translated into Chinese and passed from person to person, making him a popular subject for interviews in the Asian nation. His forecasts turned out to be correct: the number of new cases reported each day started to fall as of February 7. A week later, the mortality rate started falling as well.


Levitt received his Nobel prize for chemistry in 2013 for "the development of multiscale models for complex chemical systems." He did not in any way intend to be a prophet foretelling the end of a plague; it happened by accident. His wife Shoshan Brosh is a researcher of Chinese art and a curator for local photographers, meaning the couple splits their time between the U.S., Israel, and China.


When the pandemic broke out, Brosh wrote to friends in China to support them. “When they answered us, describing how complicated their situation was, I decided to take a deeper look at the numbers in the hope of reaching some conclusion,” Levitt explained. “The rate of infection of the virus in the Hubei province increased by 30% each day—that is a scary statistic. I am not an influenza expert but I can analyze numbers and that is exponential growth.” At this rate, the entire world should have been infected within 90 days, he said.


But then, the trend changed. When Levitt started analyzing the data on February 1, Hubei had 1,800 new cases each day and within six days this number reached 4,700, he said. “And then, on February 7, the number of new infections started to drop linearly and did not stop. A week later, the same happened with the number of the deaths. This dramatic change in the curve marked the median point and enabled better prediction of when the pandemic will end. Based on that, I concluded that the situation in all of China will improve within two weeks. And, indeed, now there are very few new infection cases.”


Israel currently does not have enough cases to provide the data needed to make estimates, Levitt said, but from what he can tell, the Ministry of Health is dealing with the pandemic in a correct, positive way. “The more severe the defensive measures taken, the more they will buy time to prepare for needed treatment and develop a vaccine.”


Levitt avoids making global forecasts. In China, he said, the number of new infections will soon reach zero, and South Korea is past the median point and can already see the end. Regarding the rest of the world, it is still hard to tell, he said. “It will end when all those who are sick will only meet people they have already infected. The goal is not to reach the situation the cruise ship experienced.”
