Norovirus Outbreak in South China School Sickens Over 100 Students

News Desk: More than 100 students at a senior secondary school in south China have fallen ill after a norovirus outbreak, prompting swift containment measures by local health and education authorities.

Officials said 103 students from Xinghui Senior High School reported symptoms of acute gastroenteritis, including vomiting and diarrhoea. All affected students are in stable condition, with no critical cases reported.

The cluster was identified after multiple students sought medical attention within a short period. Health teams quickly intervened, ordering large-scale disinfection of classrooms, dormitories and dining areas. Infected students were isolated for observation, while close contacts were placed under monitoring.

Authorities said the situation is under control, but surveillance will continue over the coming days to prevent secondary infections. Parents have been advised to keep symptomatic children at home and report any new cases immediately.

What is Norovirus?

Norovirus is a highly contagious virus that causes acute gastroenteritis and is one of the leading causes of stomach infections worldwide. Outbreaks are common in schools, hostels, cruise ships and care facilities due to close contact and shared surfaces.

How It Spreads

• Person-to-person contact

• Contaminated food or water

• Touching infected surfaces and then the mouth

• Exposure to vomit or fecal particles

Common Symptoms

• Sudden vomiting

• Watery diarrhoea

• Stomach cramps

• Nausea and mild fever

Symptoms usually appear within 12–48 hours of exposure and last 1–3 days.

Precautions and Prevention

• Wash hands thoroughly with soap and water

• Disinfect surfaces with chlorine-based cleaners

• Avoid sharing food, utensils or personal items

• Keep infected individuals isolated for at least 48 hours after recovery

Health officials noted that norovirus cases typically rise during cooler months and urged schools to maintain strict hygiene protocols to prevent further outbreaks.
