Approximately 14 days after exploring a limestone cave in northcentral Florida in February 1973, an 18-year-old female developed a respiratory illness with pronounced shortness of breath and cyanosis. The following day, an 18-year-old male presented to the hospital with similar complaints. The association of illness with their recent caving experience prompted further epidemiologic investigation. Twenty-nine members of a church-sponsored youth group explored the implicated cave. Twenty-three of them later became ill with complaints of cough, afternoon fever and sweats, chest discomfort, and dyspnea on exertion. Histoplasmin skin tests were positive in 18 of 24 individuals tested. Serum for complement fixation (CF) was positive in 12 of 26. Testing of area residents revealed a low incidence of skin test and CF positivity (7% and 0%, respectively). That spelunkers are at risk of acquiring pulmonary histoplasmosis has been noted previously; in Florida this has been related to the exploration of caves infested with bats. This is the largest reported outbreak of acute pulmonary histoplasmosis that has been associated with spelunking and further points out that only those individuals who enter the cave are at risk of acquiring the disease, and not those who reside in the surrounding area.

To define the clinical presentation of histoplasmosis among hospitalized children, we reviewed the charts of patients treated for histoplasmosis at Vanderbilt University Children's Hospital during the years 1968 through 1988. Thirty-five patients with histoplasmosis diagnosed by culture, pathologic examination, or serologic testing were identified, including 29 patients (83%) with pulmonary/mediastinal infection, 5 (14%) with disseminated disease, and 1 (3%) with primary cutaneous histoplasmosis. The most common symptoms included fever, present in 26 patients (74%), and cough, present in 20 (57%). Of 26 patients with fever, 18 (69%) had fever of > 2 weeks' duration and 7 (27%) had temperatures > or = 40.5 degrees C (> or = 105 degrees F). Abnormal physical findings were few, but 19 patients (54%) had wheezing. Chest radiographs were obtained in all cases except one; 31 (91%) showed abnormalities, including adenopathy in 25 cases (74%) and infiltrates in 19 (56%). Histoplasmin skin tests were positive for 22 (96%) of the 23 patients tested. No cases of classic disseminated histoplasmosis of infancy were identified. Histoplasmosis should be considered in the differential diagnosis when children living in endemic areas are evaluated for persistent fever, cough, and/or wheezing, particularly if adenopathy is seen on the chest radiograph.
