Anthony Fauci, M.D., the top U.S. infectious disease expert, has said there is precedent with other infections like influenza that when the virus gets warmer it goes down in its ability to spread, but no one should assume that people are going to be rescued by a change in the weather.
Bryan added that the virus dies even more quickly in aerosol form when exposed to the same heat and humidity levels.
Researchers have identified that heat and humidity are weak links in the chain of the virus, Bryan said, noting it would be irresponsible to say that summer will kill the virus.
President Donald Trump has said the findings are a suggestion at this point.
