Tuberculosis (TB) is a major zoonotic disease of public health importance worldwide. Its burden is more in developing countries due to inadequate surveillance, co-infection with HIV/AIDS and poor social amenities; hence consumption of unpasteurized milk, contaminated meat and inhalation of infected droplets from animals or patients with active TB are the major risk practices. A survey was conducted on TB prevalence from 2013 to 2014 while patients records from TB and Leprosy units of hospitals in the three Agricultural zones (Ogoja, Ikom and Calabar) of Cross River State, Nigeria were assessed from 2000 to 2010. Out of 1,170 sampled patients, 8 (0.7%) were positive, of which 6 and 2 isolates were identified as M. tuberculosis and M. bovis, respectively. Out of 52,558 studied patients files, 235 (0.4%) were positive with varied annual prevalence; the highest (1.0%) and lowest (0.2%) in 2009 and 2011, respectively. The prevalence was higher in dry (0.9% and 0.5%) than the rainy season (0.5% and 0.4%), in females (0.9% and 0.5%) than the males (0.4% and 0.4%) in the survey and retrospective studies, respectively. The age distribution of TB among the patients were; (0% and 0.3%), (0.4% and 0.4%), (0.7% and 0.4%) and (1.5% and 0.7%) for those (≤ 18), (19-40), (41-60) and ( 60) yrs old in the survey and retrospective study, respectively. TB is prevalent in human patients in Cross River State hence, the need for sustainable campaign, continuous surveillance and private/ public health partnership in accurate and early diagnosis, treatment and one health approach to its control. |
