RESUMO

Falciparum malaria was a major problem among displaced Haitians in temporary camps at the US Naval Base, Guantanamo Bay, Cuba. From December 1991 to March 1992, 235 cases of unmixed falciparum malaria were diagnosed in the laboratory, giving a cumulative attack rate of 160 per 10 000 camp residents. All cases were successfully treated with oral chloroquine. Children under 16 years of age, and especially females, were at substantially higher risk of infection (attack rate 481/10 000 versus 278/ 10 000 for males in the same age range). Malaria attack rates by place of birth in Haiti were calculated per 10 000 people as Cayemite, 530; Baraderes, 375; Pestel, 285; Port Au Prince, 247; and La Gonave, 36. The time to onset of clinical malaria after embarking at the Naval Base ranged from one to 58 d. No malaria transmission was demonstrated in the migrant camp. A non-systematic survey showed a 1.7% prevalence (95% confidence interval +/- 1.9%) of falciparum malaria among asymptomatic residents. Health practitioners in areas that may receive Haitian migrants should plan to care for malaria and preventive medicine measures are indicated, as imported malaria could be transmitted in areas where competent vectors are indigenous.

RESUMO

Between November 1991 and June 1993, approximately 11,000 Haitian migrants were screened for active tuberculosis and human immunodeficiency virus type 1 (HIV-1) infection at the U.S. Naval Base in Guantánamo Bay, Cuba. Cultures of specimens from 37 of these patients yielded Mycobacterium tuberculosis; eight (22%) of these isolates were resistant to standard medications, including isoniazid (22%), rifampin (0), ethambutol (3%), and streptomycin (3%). Two isolates (5.4%) were resistant to two drugs simultaneously. All but one of 340 patients who were treated for presumptive active tuberculosis and who were followed up for about 1 month had a favorable initial clinical response to a standard four-drug regimen. Among 259 HIV-1-infected patients who had normal findings on screening chest radiographs and who received prophylaxis with isoniazid, there were 1.8 incident cases of active tuberculosis per 100 person-years; this rate was 76% lower than that (reported by others) among HIV-1-infected Haitian patients who were not treated with isoniazid. No serious toxic effects due to standard four-drug regimens or to prophylaxis with isoniazid were observed. These data suggest that standard empirical therapeutic interventions for tuberculosis are adequate and well tolerated in Haitian migrants.
