Sacramento, CA - January 29, 2026 - California health officials are reporting a significant increase in norovirus cases across the state, prompting warnings about the virus's highly contagious nature and its ability to linger in household environments. While typically a winter ailment, the current surge appears to be exhibiting unusual persistence, raising concerns about prolonged community spread.

Norovirus, often mistakenly called the "stomach flu" (though unrelated to influenza), is a highly infectious virus that causes gastroenteritis - inflammation of the stomach and intestines. Symptoms manifest as acute nausea, forceful vomiting, diarrhea, and debilitating stomach cramps. The illness typically resolves within a short timeframe of 1-3 days for most individuals, but can be particularly dangerous for vulnerable populations including infants, young children, the elderly, and those with compromised immune systems. In severe cases, dehydration can lead to hospitalization.

"We're observing a higher than usual incidence of norovirus, and what's particularly worrying is its tenacity," explained Dr. Karen Han, Epidemiologist with the California Department of Public Health, in a press briefing earlier today. "The virus is notoriously difficult to eradicate from surfaces, and we're finding that households are becoming focal points for repeated infection. People are getting sick, thinking they've cleaned sufficiently, and then re-contracting the virus from seemingly innocuous surfaces."

The primary mode of transmission is fecal-oral, meaning the virus spreads through contact with contaminated food, water, or surfaces. This happens when someone infected doesn't properly wash their hands after using the restroom or before handling food. Norovirus is remarkably resilient; it can survive on surfaces for extended periods and withstand many common cleaning agents. Simple hand sanitizers, while effective against some germs, are not reliably effective against norovirus, emphasizing the crucial role of soap and water.

The Home as a Hotspot

Experts believe that the current surge is fueled by the virus's ability to thrive within home environments. Common touchpoints - doorknobs, light switches, faucets, toilet handles, and even kitchen countertops - can harbor the virus for weeks, leading to repeated exposures. Even seemingly thorough cleaning may not be enough to fully eliminate the threat. Health officials recommend using a bleach-based disinfectant, following the manufacturer's instructions carefully, for effective sanitization.

Dr. Han highlighted the importance of meticulous cleaning practices, especially when someone in the household is sick. "It's not enough to just wipe down surfaces. You need to disinfect them properly. And be diligent about handwashing - frequently and thoroughly. Think after using the bathroom, before preparing food, and before eating."

Prevention Strategies & Public Health Recommendations

The California Department of Public Health is reiterating the following preventative measures:

• Frequent Handwashing: Wash hands thoroughly with soap and water for at least 20 seconds, particularly after using the restroom, changing diapers, and before preparing or eating food.
• Surface Disinfection: Regularly clean and disinfect frequently touched surfaces with a bleach-based cleaner.
• Food Safety: Wash fruits and vegetables meticulously before consumption. Cook seafood thoroughly.
• Isolation: If you suspect you have norovirus, stay home from work or school and avoid close contact with others until at least 24 hours after symptoms have subsided. This is critical to preventing further spread.
• Laundry Practices: Carefully wash any potentially contaminated laundry (clothing, bedding) using hot water and detergent.
• Avoid Sharing: Do not share food, drinks, or utensils with others when sick.

The CDPH website ([ https://www.cdph.ca.gov/ ]) provides detailed information about norovirus, including symptoms, prevention, and treatment. The department is also collaborating with local health agencies to monitor the outbreak and provide support to affected communities.

This current surge serves as a stark reminder of the importance of vigilant hygiene practices, not just during illness but as a routine measure to protect yourself and your community. The prolonged presence of norovirus in homes necessitates a more robust and sustained approach to cleaning and sanitation to effectively curb its spread.
