A small percentage of people in remote Amazon communities in Peru appear to be naturally protected against rabies and to have survived rabies infection without treatment, according to a report from researchers from the US Centers for Disease Control and Prevention in collaboration with the Peruvian Ministry of Health (Gilbert AT et al. Am J Trop Med Hyg. 2012;87:206-215).
In May 2010, researchers interviewed 92 people from 2 communities, where there had been outbreaks of fatal infections with rabies caused by bites by vampire bats. A questionnaire captured demographic information, information about exposure to bats, and whether the individuals had had pre-exposure or postexposure prophylaxis.
