Norovirus cases rising in Georgia and South Carolina as winter begins

Norovirus infections are climbing across Georgia and South Carolina as winter settles in, prompting health experts to stress a familiar message: wash your hands well, clean shared spaces and stay alert to signs of dehydration. CBS Newsreports that CDC surveillance and wastewater readings show cases rising nationwide, with the Southeast now seeing a steady uptick.

The symptoms aren’t subtle. Dr. Tim Connelly, an internal medicine physician at Memorial Health in Savannah, told CBS News that nausea, vomiting, diarrhea and abdominal pain are the most common complaints. Savannah hasn’t seen a major wave yet, he said, but trends suggest more infections are likely in the coming weeks.

Because norovirus spreads so easily — through contaminated surfaces, food and close contact — household outbreaks can move quickly. Connelly emphasized to CBS News that soap and water remain the best protection. Hand sanitizer helps, he said, but isn’t as effective against this particular virus. A 20-second wash is still the gold standard.

Cleaning routines matter too. Many everyday cleaners can’t kill norovirus, so Connelly advised using bleach-based products on high-touch areas like doorknobs, counters and bathroom surfaces. “Bleach kills a lot of things, particularly viruses,” he told CBS News.

For those who do get sick, staying hydrated is critical. Vomiting and diarrhea can cause dangerous electrolyte imbalances, and Connelly urged people to seek medical care if they feel faint, increasingly weak or if symptoms worsen.

A swab test can confirm norovirus, and Connelly told CBS News that anyone experiencing symptoms should contact their doctor. Testing helps rule out other treatable illnesses and ensures people get appropriate care as cases continue to rise.
