Winter's Stomach Bug: Norovirus on the Rise

This winter, a nasty stomach bug is making a comeback in the US. Norovirus, the leading cause of foodborne illnesses, is seeing a surge in cases. In the first week of December, there were 91 outbreaks reported, a jump from 69 the previous week. Outbreaks are common in places where people are close together, like schools, nursing homes, and cruise ships.

Norovirus spreads easily, needing just a few particles to make someone sick. It causes sudden vomiting and diarrhea, along with other symptoms like nausea and headaches. The illness usually lasts one to three days, but it can be serious for young children, older adults, and those with weakened immune systems. Preventing norovirus involves good handwashing and cleaning surfaces with disinfectants. There's no medicine to treat it, so staying hydrated is key. If you get dehydrated, it's important to see a doctor.
