The epidemiology of rabies and canine distemper in the Serengeti, Tanzania.

Higher-density dog populations west of Tanzania's Serengeti National Park serve as the primary reservoir for both rabies and canine distemper, according to a comprehensive epidemiological study. The research, combining cross-sectional and longitudinal approaches, identified distinct infection patterns between two domestic dog populations bordering the park, necessitating tailored disease control strategies. While dogs, not wildlife, were confirmed as the rabies reservoir—supported by virus typing and case surveillance data—rabies persistence was more likely sustained by infectious carriers rather than slow-incubators or immune animals. Canine distemper exhibited stable endemicity in high-density dog populations but occurred sporadically in lower-density areas. The study also evaluated serological tests, finding that a liquid-phase blocking ELISA (BE) was the most specific assay for rabies detection, while an indirect ELISA was deemed non-specific.
