[Spotted fever group rickettsial disease in Argentinean travelers].

During 1996, four patients that returned from South Africa suffering from rickettsiosis were attended at the Traveler's Medicine practice of our hospital. All of them presented fever, headache and cutaneous scar. One of these presented maculopapular rash, while the rest developed a vesicular rash. The Weil-Felix reaction was negative and the immunofluorescence test for Rickettsia conorii was positive in all cases. None of the patients remembered having been bitten by any insects, however all of them had been staying in or going through a wild environment. All the patients were treated with doxycycline and presented a good outcome.
