We can provide a reasonable estimate for the near complete thermal destruction of the novel coronavirus SARS-CoV-2, which causes COVID-19. Temperatures above 65°C (149°F) are expected to almost completely eliminate the virus. A study also found that heat could kill more than 99.9% of the virus at temperatures of 40 degrees Celsius (104 F). The research conducted in the Department of Microbiology is helping society combat COVID-19 through the use of heat and ultraviolet light. Many people thought that the virus would disappear as summer weather warmed up and became more humid.
However, even though the virus doesn't work well in the heat, hot summer temperatures had no real effect on it.
