China CDC urges precaution against peak season for acute infectious diarrhea

China is entering the annual peak season for acute infectious diarrhea caused by pathogens such as norovirus and rotavirus, with disease control authorities advising special precautions to protect vulnerable children.

Norovirus, which remains highly active from October through March, poses significant risks in crowded settings like schools, childcare facilities, elderly care homes and hospitals, according to the Chinese Center for Disease Control and Prevention.

Common symptoms of norovirus infection include nausea, vomiting, fever, abdominal pain and diarrhea. While most norovirus patients typically recover within two to three days without special treatment, infants and elderly individuals with chronic conditions require particular attention due to potential severe symptoms.

The peak season for rotavirus begins around September and primarily affects young children, with symptoms such as diarrhea, vomiting and fever in infants and toddlers.

To combat these seasonal threats, health authorities recommend vaccinating children against rotavirus promptly and maintaining strict hand hygiene practices.

Nurseries and schools have also been advised to enhance health management for kitchen workers and caregivers, requiring them to wear masks, practice proper hand hygiene, and immediately leave their posts if experiencing symptoms like diarrhea or vomiting.
