Epidemiologic survey of Mansonella ozzardi in Corail, Haiti.
An epidemiologic (cross-sectional study) survey on 462 inhabitants in Corail, Haiti showed that 16.5% were infected with Mansonella ozzardi. This finding was determined from a single 20-μL sample of finger prick blood from each person. Among children, < 2% had a detectable microfilaremia. In persons > 15 years of age, the prevalence of infection for males and females was 23% and 21%, respectively. In general, the microfilaremias were low and 70% of positive persons had < 10 microfilariae per 20 μL of blood; only 5% had > 50 microfilariae. This study shows that persons living near mangrove marshes that are breeding sites for Culicoides furens and C. barbosai biting midges, which are recognized vectors of M. ozzardi in Haiti, are consequently more frequently infected than those living in downtown area of Corail or inland.
