title: [Key aspects regarding HIV and travel].
abstract: The risk of contracting a sexually transmitted infection while traveling abroad is increased in certain populations. Pre-travel consultation should include the education of travelers on the prevalence of HIV in the countries visited and on appropriate prevention measures. In patients infected with HIV (PHIV), combined antiretroviral therapy (cART) improves immunity, enabling them to travel with less risk for their health. Pre-travel consultation of PVIH has the following objectives: to determine immune status, to update immunization and to decide on anti-malaria drug prophylaxis, taking into account potential drug interactions with antiretroviral therapy. Vaccine response and duration of protection is shorter-lived in PVIH, especially if the CD4 count is below 200 cells/mm3 and the HIV viral load is detectable. Therefore cART is a cornerstone for disease prevention among patients infected with HIV who travel.
