Norovirus is a highly contagious virus that causes gastroenteritis, commonly known as the stomach flu.
It spreads through contaminated food or water, contact with infected individuals, or touching contaminated surfaces.
Symptoms include nausea, vomiting, diarrhea, stomach pain, fever, headache, body aches, fatigue, dehydration, and loss of appetite.
Symptoms usually appear 12 to 48 hours after exposure to the virus.
The illness typically lasts for 1 to 3 days and is self-limiting.
Norovirus is highly contagious and can spread rapidly in crowded or enclosed environments such as daycare centers, schools, cruise ships, and nursing homes.
Prevention measures include frequent handwashing with soap and water, avoiding contact with infected individuals, disinfecting contaminated surfaces, and practicing good food hygiene.
There is no specific treatment for norovirus infection. Management involves staying hydrated, resting, and treating symptoms such as fever and pain.
Complications are rare but may include severe dehydration, especially in young children, older adults, and immunocompromised individuals.
Currently, there is no vaccine available for norovirus, but researchers are working on developing one.
