In a case of epidemic, the basic reproduction number plays a crucial role as measure of its impact. This paper presents a simple mathematical model of the epidemic population dynamics of TBC, and a TBC controlling model with vaccine preexposure. A combined strategy of vaccination and medication against TBC epidemic derived from the basic reproduction number is also discussed.
