title: [Leptospirosis in Espiritu Santo, Vanuatu, 8 case reports].
abstract: Our review of the literature on leptospirosis in Vanatu turned up only one previous report describing 3 cases at the Central Port Vila Hospital in 1992. The purpose of this report is to describe 8 cases of leptospirosis in patients admitted to the North District Hospital on Espiritu Santo Island in 1997. There were 6 men and 2 women with a mean age of 45 +/- 16 years. At the onset of the disease patients presented fever, myalgia, and diarrhea. After an average of four days initial symptoms were followed by visceral involvement with severe jaundice in all cases. Kidney failure occurred in 6 cases and neurological manifestations in 5. Subconjunctival hemorrhage was observed in 2 cases. Laboratory studies demonstrated hyperleukocytosis in 6 cases and liver enzyme abnormalities in 6 cases. Three patients presented Weil syndrome. Microscopic agglutination testing performed more than a week after the onset of disease was positive at 1/800 in 6 cases and at 1/200 with typical clinical abnormalities and positive serum PCR in 2 cases. All patients responded favorably to antimicrobial therapy using penicillin IV and symptomatic treatment. The estimated incidence of leptospirosis in the North District of the Island of Espiritu Santo, in 1997 was 40/100,000 person-year but this was probably an underestimation because of unawareness of the disease, poor access to medical care, and underdiagnosis.
