Exclusions
All cases must be excluded from work or school until free from diarrhoea and vomiting for 48 hours as a minimum
In the case of an 'at risk' group, exclude for longer especially if they are and review the need for microbiological clearance:
food handlers
staff of health care facilities
children under five years
people with learning disabilities
In the case of 'non risk' groups there is no microbiology follow up
most food poisoning - no screening of contacts necessary, except in the case of Typhoid and E.coli
Exposures to infected water
