Travel-associated skin disease

Abstract

Travel associated skin disease is extremely common and a frequent cause of the returning traveller seeking medical attention. Widespread cutaneous eruptions usually represent reactive rashes, indicating an underlying systemic infection or allergic reaction. Patients with disseminated or spreading rashes following travel often present with fever and malaise. In contrast, those presenting with localised skin disease such as a blister, nodule, plaque, ulcer etc are usually well in themselves but have sustained a bite/sting/penetrating injury or introduction of infection directly into the skin at the affected site. As a general rule widespread rashes are investigated with blood tests/serology and localised lesions with a skin biopsy for culture and histology.
