"It is extremely contagious. And people don't wash their hands, especially kids. Previously thought to be associated with cruise ships and preschools, once the virus is circulating, it can quickly become an outbreak. Norovirus outbreaks often begin at salad bars and cruise ships and places where people congregate closely."
"Norovirus causes vomiting, diarrhea and painful stomach cramps, and can infect people of all ages. Other flu-like symptoms include fever, headache and body aches, and can lead to dehydration, especially among small children and elderly adults. In most cases, people get sick when coming into contact with the virus while caring for someone who's contagious, sharing food with them or touching contaminated surfaces."
Northern California is experiencing a norovirus outbreak alongside extreme heat conditions. WastewaterSCAN has detected high levels of the contagious gastrointestinal virus in western San Francisco, Marin, Novato, Palo Alto, and Sunnyvale, with moderate levels in other Bay Area locations. Norovirus causes vomiting, diarrhea, stomach cramps, fever, headache, and body aches, potentially leading to dehydration in vulnerable populations. Transmission occurs through contact with infected individuals, shared food, contaminated surfaces, and raw oysters. The virus is extremely contagious and spreads rapidly in crowded settings. Hand-washing is critical for prevention, particularly among children who frequently neglect this practice.
