Flu season is here in New Jersey, but other illnesses are in full swing in the Garden State. Here are the symptoms and how long you're contagious.

Most U.S. states are reporting high or very high flu-like activity, while COVID-19 rates remain lower than this time last year.

This fall saw an unusually high number of cases of “walking” or mycoplasma pneumonia, a mild pneumonia that typically causes a severe cough but less fatigue than more serious forms of the disease.

Influenza A, COVID-19 and norovirus (stomach flu) are on the rise, according to the Centers for Disease Control and Prevention. But there's a fourth "bug" the public should be aware of: respiratory syncytial virus. RSV causes cold-like symptoms and affects the breathing passages and lungs.

Bon Secours and Prisma Health are implementing new visitor restrictions as cases of influenza and respiratory illnesses rise across the country.

As the flu season goes into overdrive, how do you know if you have the viral infection or another of the nasty diseases that tend to be more prevalent in the winter?

Cold, flu, norovirus, and COVID-19 share overlapping symptoms like fever, cough, and fatigue, but differ in severity and duration. Handwashing, vaccines, and staying home when sick can help prevent infections.
