Norovirus, causing vomiting and diarrhea, can reinfect people multiple times in winter due to short immunity, and spreads easily despite alcohol sanitizers; thorough handwashing and cleaning are crucial to stop transmission.
The UK Health Security Agency warns that norovirus can reinfect people multiple times during the winter, as immunity is short-lived.
The highly contagious virus causes vomiting, diarrhea, and stomach cramps, with symptoms lasting two to three days.
Individuals remain infectious for up to 48 hours after symptoms end, so the NHS advises staying away from schools, workplaces, and care homes until then.
Alcohol-based sanitizers are ineffective; thorough handwashing with soap and water is essential.
Surfaces, clothing, and bedding should be cleaned or washed at 60°C to prevent spread.
Staying hydrated and avoiding public spaces while symptomatic are key to reducing transmission.
