[Practical advice for travellers with immune disorders]

For patients with immune disorders, the risk of infection during travel depends on the cause and severity of the immune disorder and the type of travel. Immunocompromised travellers experience more severe effects of illness than those without immune disorders. Some risks can be reduced or avoided by taking adequate precautions and, in some cases, modifying travel plans. Ensuring adequate medication use during the trip requires careful planning prior to travel. Regarding vaccination, immunocompromised travellers may have an impaired ability to generate antibodies; live attenuated vaccines are often contraindicated. The treating physician must take a proactive role when an immunocompromised patient indicates that he or she plans to travel. Protocols developed by the Dutch National Coordination Centre for Travellers Health (LCR) provide practical advice regarding a number of situations. Provided that they are given proper individualised advice, there is little concrete evidence to suggest that these patients should not travel anywhere they wish.
