Seasons Change: Be Prepared for Respiratory Viruses

Seasons Change: Be Prepared for Respiratory Viruses


Viruses are inconsistent. Learn what to expect this season.

September 29, 2022

Viruses have always been unpredictable, and the COVID-19 pandemic has made inconsistency the norm. Even the flu has changed. Last year the number of people infected with flu went down, and this year, cases may spike. 

With so much uncertainty, and so many viruses out there, what can we do to protect ourselves and others, especially as seasons change?  


Expect viruses all year


Although respiratory viruses, including coronaviruses, typically thrive in fall and winter, in today’s new normal, there really is no COVID season. Cold and flu seasons have changed, too.

“We typically think of viruses having a seasonality, but we’re learning that COVID doesn’t,” said Jamie P. Deeter, M.S., Ph.D., a scientific partner at Roche Diagnostics. “We expect higher rates of infection in winter months, but unfortunately this virus is going to circulate all year long.”

Typically, when predicting how the flu and other viruses will affect the U.S., we look at Australia since winter just ended there. This year,  there was a rise in flu infections for kids 5 to 9 years old, followed by kids under 4 and teenagers. 

There could be many reasons for the increase in infections. Now that COVID protocols like mask mandates have lifted, people are more likely to spread colds, flu and other types of viruses. 

According to the Centers for Disease Control and Prevention, in addition to vaccination, staying at home when feeling sick and regular handwashing remain one of the best ways to avoid illness and prevent spreading germs to others. So remind everyone – and yourself – to wash up frequently.
