State Public Health experts are warning about a nasty stomach bug making the rounds. Norovirus rates have been trending up lately, with a new strain of the virus, and doctors say there could be more cases as people gather over the holidays. It spreads through infected body fluids, and virus particles are very small, so the best strategy to avoid it is to avoid people who are sick, wash your hands often, and thoroughly sanitize cooking surfaces, utensils, and wash clothes in hot water. People usually recover quickly from Norovirus, so if you get sick, the best way to recover is to stay hydrated and practice good hygiene.
