(KFVS) - The Centers for Disease Control and Prevention say more than 80 percent of norovirus outbreaks occur from November to April. The norovirus causes vomiting and diarrhea and is very contagious.
The CDC estimates that more than 20 million people, or about one in every 15 Americans, are infected with norovirus.
“Norovirus is the most common cause of stomach illness in the country,” said Illinois Department of Public Health Director Dr. LaMar Hasbrouck. “However, the easiest way to avoid becoming ill is to wash your hands. Viruses can contaminate surfaces and objects touched by someone who is ill. If your hand then comes in contact with your mouth, chances are you will end up becoming ill.”
