Your winter illness guide: Why norovirus and RSV are on the rise, and what to expect from COVID-19 and the flu

COVID-19, RSV , the flu and norovirus are more difficult to pin down because it’s a newer virus than RSV or influenza.

Symptoms include cough, shortness of breath, fever, achiness, congestion and sore throat.

The elderly, pregnant women, people with preexisting conditions and the immunocompromised are particularly susceptible to complications from the virus.

Most recent surveillance data from the CDC shows minimal to moderate flu activity in most of the U.S. Flu season typically starts in December , rises significantly in January and February , and then starts to decline in March .

Anyone older than 6 months is eligible for the influenza vaccine, which can reduce the risk of getting sick by up to 60% .

RSV is elevated and continues to rise, with infections increasing in several states.

Norovirus is the leading cause of vomiting and diarrhea from acute gastroenteritis in the U.S. There aren’t any antivirals for RSV , so the CDC recommends that you manage symptoms at home with over-the-counter fever reducers and pain relievers.

Winter is prime time for norovirus and other viruses to spread, as we gather together indoors.
