How to prevent and control norovirus infection?
As the seasons change, now enter the high-incidence period for norovirus-induced gastroenteritis. Norovirus infection, also called the "winter vomiting bug", is a stomach bug that causes vomiting and diarrhoea. Norovirus can spread very easily through various means, including:
1. Foodborne: Consumption of raw shellfish, such as oysters, and fruits or vegetables contaminated with norovirus, as well as drinking water contaminated with the virus, can lead to infection.
2. Contact: Touching surfaces or objects contaminated with the virus and then touching the mouth without thorough handwashing can result in infection.
3. Airborne Transmission: Aerosolized particles from vomit or feces can lead to airborne transmission, particularly in enclosed and crowded environments like hospitals and schools.
After norovirus infection, symptoms such as nausea, vomiting, abdominal pain, and diarrhea may occur. In children, vomiting is more common, while adults typically experience diarrhea. The incubation period is short, ranging from 12 hours to a maximum of 72 hours, with most individuals developing symptoms within two days.
Wizbiotech developed norovirus antigen detection kit (colloidal gold method), which serves as an adjunct tool for clinicians. The norovirus test kit is a stool test that qualitatively detects norovirus antigens in fecal samples with ease of use and rapid visual interpretation of results. While it does not replace clinical diagnosis, it can be employed as an early screening and diagnostic aid, enabling medical professionals to take timely actions to mitigate the spread of the virus. This approach helps protect public health, especially among vulnerable populations such as those in schools and childcare facilities.
