Final answer:
Norovirus is a contagious virus causing gastroenteritis, often on cruise ships, with symptoms like diarrhea and vomiting. Good hygiene, hand washing, and careful food preparation are key prevention measures.
Step-by-step explanation:
Norovirus: Source, Symptoms, and Prevention
Norovirus, commonly identified as Norwalk virus, is a highly contagious virus that causes gastroenteritis, leading to stomach and intestinal inflammation. It is often found in confined spaces, like cruise ships, and can affect infants, young children, and the elderly. The source of norovirus is typically through contaminated food or water and can also spread through direct contact and touching contaminated surfaces.
Symptoms of Norovirus
Norovirus symptoms include watery diarrhea, mild cramps, fever, and sometimes projectile vomiting. These symptoms usually develop 12 to 48 hours after exposure and tend to resolve within a couple of days. It is important to watch for signs of dehydration, which is a common complication of the virus.
Prevention Measures
To prevent norovirus, practicing good hygiene, especially hand washing, and careful preparation of food are essential. In healthcare settings and where outbreaks may occur, such as on cruise ships, rigorous sanitation measures are necessary to mitigate the spread of infection. Rehydration therapy and electrolyte replacement may be required for those affected by the virus.
