Objetivos:

Investigar o surto de histoplasmose em bombeiros no Distrito federal/DF, ocorrido em junho de 2017.

Métodos:

Realizou-se um estudo de coorte por meio das entrevistas realizadas com os bombeiros mediante um questionário semiestruturado. Considerou-se infectado o bombeiro que apresentou tomografia de tórax sugestiva de histoplasmose ou reagente nos testes de imunodifusão e/ou Western blot. Coletou-se amostra ambiental e realizou-se Nested PCR específico para Histoplasma capsulatum.

Resultados:

Entre 35 bombeiros, 94,3% eram homens; com a mediana de idade de 37 (24-45) anos, 28 foram classificados como infectados. A média de permanência dentro da caverna foi 25 minutos. O fator de risco associado à infecção foi o ato de entrar na caverna (RR=3,86; RA=71,6; p<0,02). Entre 14 amostras ambientais, 50% foram positivas para H. capsulatum.

Conclusão:

Confirmou-se o surto de histoplasmose de bombeiros em Brazlândia-DF, e foram tomadas ações como a interdição da caverna e o tratamento dos bombeiros.

Methods:

A cohort study was conducted through interviews with firefighters by means of a semi-structured questionnaire. Firefighters who presented chest tomography suggestive of histoplasmosis or reacted to immunodiffusion and/or Western blot tests were considered infected. Environmental samples were collected and Nested PCR specific for Histoplasma capsulatum was performed.

Results:

Among 35 firefighters, 94.3% were men; with a median age of 37 (24-45) years, 28 were classified as infected. The average length of stay inside the cave was 25 minutes. The risk factor associated with infection was the act of entering the cave (RR = 3.86, RA = 71.6, p <0.02). Among 14 environmental samples, 50% were positive for H. capsulatum.

Conclusion:

The outbreak of histoplasmosis in firefighters in Brazlândia-DF was confirmed, and actions were taken such as banning the cave and treating the firefighters
