As part of my work for NYU’s School of Global Public Health, I have been compiling and comparing key metrics for the most severe global pandemics that occurred in the past 100 years.

I am comparing COVID-19 metrics to seasonal influenza, 1918 Spanish flu, 1957 Asian flu, 1968 Hong Kong flu, and 2009-10 H1N1. There are many similarities and differences that can be observed. Aside from the astonishing speed of vaccine development to combat COVID-19, there are three interesting findings.

The good news is that there are currently 35 companies racing to create a vaccine and at least 52 vaccine programs underway.

WHO director Tedros Adhanom Ghebreyesus stated that the main reason for the declaration “is not what is happening in China but what is happening in other countries”. Ghebreyesus made sure to praise the measures and the ways in which Chinese authorities are controlling this outbreak. Continue Reading
