Basic reproduction number for the Brazilian Spotted Fever

Journal of Theoretical Biology, 2018
Brazilian Spotted Fever (BSF) is an emerging and lethal disease in South America which basic reproduction number (R0) is unknown. Calculating R0 for this disease is crucial to design control interventions and prevent human deaths. BSF endemic areas are related to the presence of capybaras Hydrochoerus hydrochaeris, amplifier hosts of Rickettsia ...
