"Higher levels of norovirus infections were detected in the wastewater of the western side of San Francisco, as well as Central Marin County, Novato, and Redwood City. Based on the site's line graph data, moderate levels were found on the eastern side of SF, Santa Rosa, Vallejo, San Jose, and Palo Alto."
"Common norovirus symptoms include vomiting, diarrhea, and stomach cramps, along with fever, headache, and body aches, which typically develop 12 to 48 hours after exposure, according to the US Centers for Disease Control. The virus can lead to dehydration, especially in small children and elderly adults."
"The virus, which is highly contagious, is typically spread through contaminated surfaces and food, as well as coming into contact with those with the virus. The CDC also warns that raw shellfish, including oysters, can also carry the norovirus."
"It is extremely contagious, Dr. Monica Gandhi, an infectious disease specialist at UC San Francisco, told SFGate, emphasizing that hand-washing is essential. And people don't wash their hands, especially kids."
Multiple Bay Area locations are reporting increased norovirus activity based on wastewater analysis from WastewaterSCAN. Higher infection levels were detected in western San Francisco, Central Marin County, Novato, and Redwood City, while moderate levels appeared in eastern San Francisco, Santa Rosa, Vallejo, San Jose, and Palo Alto. Norovirus symptoms include vomiting, diarrhea, stomach cramps, fever, headache, and body aches, typically appearing 12 to 48 hours after exposure. The highly contagious virus spreads through contaminated surfaces, food, and direct contact with infected individuals. Raw shellfish like oysters can carry the virus. Dehydration poses particular risk for children and elderly adults. Hand-washing and fluid intake are critical preventive measures. Recent cruise ship outbreaks, including a Princess cruise with over 150 infections, highlight the virus's rapid transmission in close quarters.
