I have read several comments here on Nairaland of people praising our hot weather for deterring COVID-19. Well, WHO says:

COVID-19 virus can be transmitted in areas with hot and humid climates
From the evidence so far, the COVID-19 virus can be transmitted in ALL AREAS, including areas with hot and humid weather. Regardless of climate, adopt protective measures if you live in, or travel to an area reporting COVID-19. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.
