Why Are Norovirus Cases Spiking This Winter?

This winter, a nasty stomach bug called norovirus is causing a lot of trouble in the United States. According to new data from the Centers for Disease Control and Prevention, the number of outbreaks has jumped from 69 to 91 in just one week. This time last year, we only saw 65 cases. But what exactly is norovirus? It's the main cause of foodborne illnesses in the U. S. , with symptoms like sudden vomiting and diarrhea. These outbreaks are common in places where people are close, like cruise ships, schools, and nursing homes. Norovirus spreads easily, and it only takes a few virus particles to make you sick. Each year, the U. S. sees around 2, 500 outbreaks, with the most happening between November and April. While most people get better in a couple of days, the virus can be serious. It causes an average of 900 deaths and over 100, 000 hospitalizations annually, mostly among older adults. Young children also require lots of emergency visits due to it. So, how do you catch norovirus? Usually, sick people spread it by sharing food or utensils. It can also be picked up from contaminated food, water, or surfaces. Once you've got it, symptoms can appear quickly, within 12 to 48 hours. The best way to protect yourself is by washing your hands often and cleaning surfaces with disinfectants.
