Potential Force of Infection of Human Rabies Transmitted by Vampire Bats in the Amazonian Region of Brazil

摘要: Human rabies transmitted by bats has acquired greater epidemiologic relevance in various Latin American countries, just when cases dogs have decreased. Concern been heightened reports of increased rates biting humans villages the Amazonian region Brazil. The aim present work was to estimate potential force infection (per capita rate at which susceptible individuals acquire infection) human common vampire bat if virus were be introduced a colony close village with high bites. could then used anticipate size outbreak control programs. We an estimator incidence, adapted from models for malaria. To obtain some parameters equation, cross-sectional survey conducted Mina Nova, gold prospectors Brazil bates humans. Bats captured near dwellings and sent Rabies Diagnostic Laboratory Center Control Zoonoses (Sao Paulo, Brazil) examined. infection, hypothetical among simulated using actual data obtained study area. Of 129 people interviewed, 23.33% had attacked during year prior study, average 2.8 bites per person. Males (29.41%) more often than females (11.36%); also, adults (29.35%) children (8.33%). None 12 Nova tested positive rabies, but estimated 0.0096 person year. This risk represents 0.96 100 area residents, giving incidence 1.54 bat-transmitted (160 inhabitants). is comparable what observed similar Brazilian villages.
