Astrovirus Infections

Astroviruses are a family of RNA viruses known to cause gastroenteritis in humans and various animals. In humans, astrovirus infections are a common cause of viral diarrhea, particularly in children. The clinical manifestations of astrovirus gastroenteritis include diarrhea, vomiting, abdominal pain, and fever. While astrovirus infections are usually self-limiting, severe cases can occur, especially in immunocompromised individuals. The virus is highly contagious and spreads through the fecal-oral route, with contaminated food, water, or surfaces acting as common sources of transmission. Astrovirus infections are prevalent globally, affecting individuals of all ages. Outbreaks often occur in crowded settings, such as daycare centers, schools, and healthcare facilities. Despite their widespread impact, astrovirus infections are generally underdiagnosed, as routine diagnostic tests may not distinguish them from other causes of gastroenteritis. Molecular techniques like PCR are becoming more commonly used for accurate detection and characterization of astrovirus strains. Enhanced surveillance is crucial to understanding the epidemiology of astrovirus infections and implementing effective preventive measures, including improved hygiene practices and vaccination strategies.
