COVID-19 Transmission & Heat: What the Science Says

The World Health Organization (WHO) says that it's not yet known whether the COVID-19 virus can be transmitted in hotter weather. Based on experience with other respiratory illnesses, COVID-19 transmission may decrease with higher temperatures and humidity, but it may still be possible to become infected in tropical climates.

The WHO advises that people in all climates should continue to take steps to protect themselves, including washing hands frequently, avoiding touching their faces, maintaining physical distancing, and seeking medical care if they have symptoms.
