"Outbreaks of a highly contagious stomach bug dubbed "winter vomiting disease" are surging across the U.S. From Aug. 1 through Nov. 13, 153 outbreaks of norovirus were reported in 14 states, according to the U.S. Centers for Disease Control and Prevention. While California is not among the reporting states, data taken from wastewater monitoring also detected rising concentrations of the virus across the state and in the Bay Area in recent weeks."
"Norovirus affects the gastrointestinal system and causes vomiting and diarrhea, with symptoms typically starting 12 to 48 hours after exposure and lasting one to three days. The California Department of Public Health noted the virus spreads through contaminated surfaces, and without serious cleaning, it can linger on objects for weeks. Infectious disease expert Dr. Peter Chin-Hong stressed to SFGATE that norovirus is incredibly easy to catch. "Norovirus is one of the most contagious agents we know," he said."
Norovirus outbreaks have surged across many U.S. states, with 153 outbreaks reported Aug. 1–Nov. 13 and rising concentrations detected in wastewater, including increases in the Bay Area. More than 13% of norovirus tests were positive in Western states during Nov. 23–29. Norovirus infects the gastrointestinal system, causing vomiting and diarrhea beginning 12–48 hours after exposure and lasting one to three days. The virus spreads via contaminated surfaces and can persist on objects for weeks without thorough cleaning. No vaccine exists; treatment is supportive, focusing on fluids. Norovirus is extremely contagious and can cause illness with roughly ten particles; soap-and-water handwashing and bleach-based surface cleaners are recommended.
