WOLFF R, Marcelo. Outbreak of acute histoplasmosis in Chilean travelers to the Ecuadors jungle.: Report of six cases as an example of geographic medicine. Rev. méd. Chile [online]. 1999, vol.127, n.11, pp. 1359-1364. ISSN 0034-9887. doi: 10.4067/S0034-98871999001100010.
Eight Chilean teenagers traveled to Ecuador in January 1999, where they were bitten by mosquitoes, had contact with parakeets and lodged in poorly hygienic places; 6/8 visited for 5-10 minutes the interior of a bat cave. About a week later these 6 began with headache, myalgia and fever that lasted 2-3 weeks. 5/6 had dry cough with no respiratory distress. The index case was seen in the 2nd week of symptoms. A chest x-ray showed multiple nodular infiltrates as in the other five. Two had histoplasma serology, one was negative and the other positive at a low titer; histoplasmine skin test showed induration of 17-27 mm in all six. An acute histoplasmosis with massive exposure was diagnosed and treated with itraconazole for 3 weeks. All became asymptomatic and chest x-rays returned to normal. Histoplasmosis (non existent endogenously in Chile) is, among other geographic and tropical diseases, a risk for Chilean travelers. Awareness of this in the general population and development of expertise in these diseases by local health care providers is required.
