Aircrew guide to gastroenteritis

Gastroenteritis is the most common cause of aircrew impairment with symptoms that include diarrhoea, nausea, vomiting and abdominal cramps. Most cases are caused by a virus or a bacterial infection in contaminated food or drink, both of which can easily spread to others. The greatest risk of contamination is down-route. Incidents of gastroenteritis in inflight aircrew can present a significant incapacitation risk resulting in the need to divert an aircraft or cancel flights.

We have published guidance (CAP1703) on how to spot gastroenteritis, what to do if you suspect that you are affected and how to prevent it.
