Stand-by treatment of suspected malaria in travellers.

Travellers to malarious areas are increasingly advised to carry an emergency medication for self-treatment of suspected malaria in absence of medical attention. However, no data are available so far how travellers cope with self-diagnosis and stand by treatment (SBT). We therefore investigated the frequency, circumstances and outcome of emergency self-treatment for suspected malaria in German travellers. 3434 travellers were recruited for an open prospective study by 28 different travel clinics in Germany. 2867 travellers (90.1%) who returned questionnaires after their journey were analyzed. 40 travellers (1.4 %) reported about SBT during their journey. Significant Plasmodium falciparum antibody levels could be demonstrated in only 4 of 37 SBT users (10.4 %). In another 127 travellers with febrile episodes but without SBT use, no malaria was indicated by follow-up and/or serology.
