Rickettsial diseases are increasingly reported in international travellers. Prospective studies have shown that 2-4 % of travellers returning with fever have a rickettsiosis. We discuss epidemiology, clinical findings, diagnostics, treatment and prevention of rickettsioses. In conclusion, rickettsioses should be considered in the returned traveller with fever, especially when malaria, dengue fever and typhoid fever have been excluded. There is a possibility that doxycyclin may have a profylactic effect on rickettsioses, but this thesis is only imaginary and needs further investigation.
