Climate Factors that Affect Transmission of COVID-19

A study found that SARS-CoV-2 can be highly sensitive to heat. The virus was still detectable after being left out for 14 days in a 4°C room, while the virus inactive 5 minutes after being left in a 70°C. The study also found a difference in stability on different surfaces, such as paper, plastic, and metal.  At room temperature, the virus is highly stable in a range of pH3 - pH10. However, the standard disinfectant method was still able to affect the virus, with the researchers finding no active infection in different disinfectants after an incubation of 5 minutes (except for hand soap).

Stability of SARS-CoV-2 in different environmental conditions

Cases of COVID-19 are reported all over the world, but few outbreaks are shown clustered in dry & cool climates areas. Studies and research shows that the spread of the virus favors temperate warm and cold climates rather than arid and tropical climates.
