Health officials issue warning for norovirus after spike in Southern Calfornia

COACHELLA VALLEY, Calif. (KESQ) - Health officials want to warn you that cases of norovirus, also known as the "winter vomiting disease," have been spiking across Southern California.

The highly contagious virus affects the gastrointestinal system and symptoms could last several days.

Doctors say the emergence of a new strain of norovirus could lead to 50 percent more infections than in the past year. That's why they're advising people to be alert and practice good hygiene.

"There are no antibiotics because it's a virus, and there are no anti-virals for norovirus. so the best way to protect yourself is to wash your hands frequently. So for instance, if you're at an assisted living or over 65 living, if you touch the banisters, go home and wash your hands," said Dr. Phyllis Ritchie, CEO & founder of PS Test.

For most people, norovirus clears up within a few days, but for some, especially young children and older adults, there could be complications from dehydration.
