Top 10 Foggers and Disinfectants for Hospital Visitor Areas and Ward Entrances: Lessons from the Norovirus Critical Incident at East Surrey Hospital, 2026
East Surrey Hospital declared a norovirus critical incident, restricted visiting on all wards and asked anyone with diarrhoea or vomiting in the past 48 hours not to visit. What should Thai hospital visitor areas prepare?
The Real Story from the News: No Visits Within 48 Hours of Symptoms
Surrey and Sussex Healthcare NHS Trust announced on 30 March 2026 that East Surrey Hospital declared a critical incident due to high levels of norovirus, alongside heavy emergency demand and staff sickness, stepping down on 2 April but keeping visiting restrictions on all wards.
The hospital asked that anyone with diarrhoea or vomiting in the last 48 hours not visit; visitors had to clean hands, limit movement around the site and wear masks in affected areas.
Why Choosing the Right Equipment Matters
Relatives come and go daily, bring food and share lifts, toilets and waiting rooms, so a visitor who recently had diarrhoea can carry norovirus straight onto a ward. Clear warning signs, soap handwashing at ward entrances and routine cleaning of visitor areas protect vulnerable patients.

Prefer Not to Do It Yourself? Use a Professional Service
If buying equipment is not practical or the area is too large, use the World Health Disinfection disinfection service or ozone treatment service. The team wears full protective equipment, chooses products to suit the germ and surface, and reports after the job.

Follow disease updates from Thailand's Department of Disease Control (hotline 1422) and the World Health Organization. Disinfection reduces germs in the environment and is not medical treatment; anyone with symptoms should see a doctor.
