Brotes de histoplasmosis registrados en el área andina colombiana
ResumenA review of 12 histoplasmosis outbreaks that occurred in the Colombian Andean region, are presented. According to their location, 3 were detected in each of the following states: Tolima, Caldas and Antioquia and 1 each in Cundinamarca, Boyacá and Risaralda. In 9 of the outbreaks it was possible to trace the following activities which led to the infection: visits to bat-inhabited caves, removing debris incide a hollowed tree, demolition of an old house, use of contaminated lime for fertilization, handling chickenmanure fettilised soil and the severe pruning of coffee trees. Histoplasma capsulatum var. capsulatum was isolated from environmental samples in 5 of the 8 outbreaks where it was feasible to obtain material for culture and animal inoculation. It was found that 332 persons had been in contact with the various infectious sources, including the 11 index cases (2 outbreaks had the same index case). All of them were studied by means of immunological tests designed to detect antibodies; based on the findings of reactive tests, al1 the index cases and 140 (42%) of those exposed had antibodies indicative of infection by the fungus. The above cases reveal the importance of histoplasmosis in immunocompetent individuals who, for occupational or recreational reasons, are exposed to infectious aerosols generated when disturbing the natural habitat of H. capsulatum var. capsulatum.
