title: [Epidemic of pulmonary histoplasmosis after visiting a cave in New Caledonia].
abstract: We report an epidemic of acute pulmonary histoplasmosis which occurred in February 1994 among a group of 24 persons after they had once or twice visited a cave in New Caledonia. This study describes the physical and laboratory findings, which lead to the diagnosis of histoplasmosis. Each test was evaluated. All members of the group had a physical examination, early and late serological tests, pulmonary X-rays (including CT) and some had mycological examination of bronchoalveolar washes. Mycological investigations were made on samples collected from the cave. Histoplasmic skin testing was not possible. We defined a case as a person who visited the cave in January 1994, had evocative radiological features and at least four symptoms among the following: weakness, fever, headache, arthralgia, thoracic pains, dyspnea, cough and nausea. Of the 24 exposed persons, 7 cases were considered as severe, 8 cases as moderate, and 6 cases as mild, for a total of 21 cases and an attack rate of 87.5%. There was no progression towards disseminated histoplasmosis and no recorded death. The incubation period lasted from 5 to 17 days. The symptoms were divided into three groups. In the first group, the symptoms of fever, headache and arthralgia were common and nonspecific. In the second group, the symptoms of chest pain, cough, and dyspnea which often occurred later, were less common and more specific. In the third group, the symptoms of vomiting, diarrhea and dizziness were less common. The chest X-ray showed abnormalities in 100% of the cases, and in 11 of the 21 cases the characteristic finding was a miliary.(ABSTRACT TRUNCATED AT 250 WORDS)
