Immunocompromised travellers.

Given a better quality of life and extended life expectancy in patients with immune suppression, the number of immunocompromised travellers is constantly growing. The aim of the article is to discuss travel-related health problems in immunocompromised patients, their most common destinations and reasons to travel, as well as complications associated with travel to regions with harsh environmental conditions. The article focuses on selected groups of immunocompromised travellers (ICTs), i.e., cancer patients, transplant patients receiving immunosuppressant agents, splenectomised patients and HIV-infected individuals. The most common infections and complications, including traveller's diarrhoea, vector-borne diseases (yellow fever, malaria, leishmaniasis, dengue, chikungunya), respiratory infections (including tuberculosis), and dermatoses were taken into account. Preventive measures dedicated to ICTs (pre-travel consultation, vaccinations, malaria chemoprophylaxis, prevention during travelling) have been also characterised.
