Astrovirus is a type of virus that primarily affects the gastrointestinal tract, leading to symptoms such as diarrhea, vomiting, and stomach cramps. It is most commonly found in children, but can also infect adults. The virus spreads through contaminated food, water, or surfaces, making hygiene important in preventing outbreaks. Infections caused by Astrovirus are usually mild and self-limiting, meaning they often resolve without medical treatment. However, in vulnerable populations, such as infants and the elderly, the virus can lead to dehydration and more severe health issues. Proper hydration and rest are key to recovery.
