A recent analysis suggests that a significant portion of the population remains susceptible to COVID-19, with estimates indicating that the true number of infections could be much higher than reported. The stability of the virus's spike protein may reduce the likelihood of it becoming more virulent, and the longer incubation period allows for increased transmission. A phased approach to testing and contact tracing is essential, as relying on natural herd immunity or waiting for a vaccine could lead to unacceptable death tolls.
