"Rising Norovirus Cases Spark Contagion Concerns in Northeastern U.S."

Doctors in the Philadelphia region are warning about the spread of a highly contagious norovirus, with cases on the rise in the Northeast. The CDC advises infected individuals to stay home to prevent further spread, as the virus has a quick onset and is easily transmissible. Symptoms are distinguishable from those of a common cold or flu, and preventative measures include frequent handwashing and avoiding contact with sick individuals. There is no cure for the virus, but staying home for at least 48 hours after symptoms stop is recommended, along with keeping a distance from vulnerable populations.
