The unwell returned traveller.

There are many causes of illness in the returned traveller; these range from very common and potentially self-limiting to severe and potentially life-threatening. It is important that GPs are aware of the epidemiology and incubation periods of diseases overseas to help provide a diagnosis or diagnoses. The process will help GPs identify life-threatening diseases or those that may be a public health threat. A detailed history of travel itinerary and the presenting symptoms, combined with a thorough examination and relevant investigations, are required. The treating GP requires an awareness of when extra help or referral are required.
