Runners should be further than 1.5 meters apart

The evidence so far indicates that the virus is spread from person to person through small respiratory droplets. When a person sneezes, coughs or even exhales, he or she is emitting small droplets ―often too small to see with the naked eye―, that can carry the virus. The receiving persons can be infected by inhaling...

COVID-19 asymptomatic infection estimation

Mounting evidence suggests that there is an undetected pool of COVID-19 asymptomatic but infectious cases. Estimating the number of asymptomatic infections has been crucial to understand the virus and contain its spread, which is, however, hard to be accurately counted. A new study proposes an approach of Machine Learning based fine-grained Simulator (MLSim), which integrates...
