In July 2023, norovirus—often called the "stomach flu"—presented with its classic, sudden-onset symptoms of projectile vomiting and watery, non-bloody diarrhea. Patients typically experienced intense nausea, stomach cramps, and a low-grade fever within 12 to 48 hours of exposure. Because norovirus is highly contagious and resists many hand sanitizers, outbreaks in the summer of 2023 were common in high-density environments like cruise ships and summer camps. Other symptoms included muscle aches, headaches, and general malaise. The primary danger during this period remained dehydration, especially in children and the elderly, with most cases resolving naturally within 1 to 3 days.
