Doctors warn of flu, COVID-19 and RSV risks as winter approaches
Medical experts say the upcoming fall and winter will see typical flu activity, a possible rise in COVID-19 cases, and low but present RSV circulation, emphasizing vaccination and basic preventive measures.
Doctors expect the usual pattern of respiratory illnesses to return this fall, with flu season beginning in September or October and lasting through March or April. Dr. S. Wesley Long, medical director of diagnostic microbiology at Houston Methodist Hospital, said flu A cases are already rising and that the season typically peaks in December and January. He noted that the southern-hemisphere flu season was “fairly typical,” providing a modest clue about the upcoming U.S. season.
Dr. Morgan Katz of Johns Hopkins University said indoor gatherings and reduced ventilation in colder months make viruses harder to control, adding that COVID-19 cases are likely to increase as people gather more. Dr. David Nguyen of Rush University Medical Center warned that COVID-19, while present year-round, often shows a winter peak, and that RSV usually circulates from October through winter with a January peak, though current activity is low.
Vaccination remains the primary defense, according to the physicians. Nguyen emphasized that flu, COVID-19 and RSV vaccines are important for anyone eligible, especially older adults, pregnant people and young infants. Long recommended additional measures such as avoiding crowded indoor spaces, wearing masks when appropriate and practicing good hand hygiene.
Health officials also advise testing for flu and COVID-19 when respiratory symptoms appear, as antiviral treatments are available for both illnesses.
