Can Warm Weather Stop or Slow Down the Coronavirus?

other coronaviruses suggests they can survive for more than 28 days at 4 degrees Celsius.

A study conducted 10 years ago by Kate Templeton, from the Centre for Infectious Diseases at the University of Edinburgh, UK, found that three coronaviruses – all obtained from patients with respiratory tract infections at hospitals and GP surgeries in Edinburgh – showed “marked winter seasonality”. These viruses seemed to cause infections mainly between December and April – a similar pattern to that seen with influenza. A fourth coronavirus, which was mainly found in patients with reduced immune systems, was far more sporadic.

Pandemics often don’t follow the same seasonal patterns seen in more normal outbreaks. Spanish flu, for example, peaked during the summer months, while most flu outbreaks occur during the winter.

Jan Albert, a professor of infectious disease control who specializes in viruses at the Karolinska Institute in Stockholm says, “…the big question is whether the sensitivity of this virus to [the seasons] will influence its capacity to spread in a pandemic situation. We don’t know for sure, but it should be in the back of our heads that it is possible.”
