ABSTRACT
Histoplasmosis is a systemic mycosis prevalent in the
Americas.
Humans become infected via the respiratory route by
inhaling aerosols from
soil contaminated with
bird and bat excretions. Acute
pulmonary histoplasmosis is usually asymptomatic and is more often a
self-limiting illness. We
report a series of seven acute pulmonary cases in
adults during an outbreak in Nova Friburgo city, Rio de Janeiro
State,
Brazil, in a group of
volunteers who were cleaning an old, abandoned house without using
personal protective equipment. The
patients had a favorable evolution after suitable
treatment, but all required
hospitalization.
