At the beginning of the coronavirus pandemic, there were high hopes that hot summer temperatures could reduce its spread. While summer hasn’t brought much relief, the link between weather and COVID-19 continues to be a hot topic.
Weather affects the environment in which the coronavirus must survive before infecting a new host, but temperature also affects human behavior, which can increase transmission. A study by the University of Texas at Austin brings some clarity to the role of weather in COVID-19 infection. A new study found that temperature and humidity do not play a significant role in the spread of the coronavirus per se.
This means that no matter how hot or cold it is outside, the transmission of COVID-19 from one person to another is almost entirely dependent on human behavior. “The impact of the weather is small, and other features are more influential than the weather,” said Dev Niyogi, a professor at the Cockrell School at the University of Texas.
