Norovirus is basically the bathroom bug from hell—super contagious and crazy hard to avoid, especially in winter. It only takes a few virus particles to get you sick, and it spreads like wildfire in places like cruise ships, daycares, and airports. If you catch it, expect sudden nausea, vomiting, and diarrhea, but most people recover at home. No vaccine yet, so wash your hands like a pro and steer clear of potlucks and buffets! #Health #BodyHealth #Norovirus
