Background:
Tuberculosis (TB) is a major public health problem in developing countries. WHO estimates the prevalence in Cameroon at 17.7% (179/100,000).
Objectives:
To determine the prevalence of TB and assess the level of knowledge and practices towards TB prevention among residents of the Bamenda III sub-division of North West Cameroon.
Methods:
A retrospective study design was used to generate data on the prevalence of TB from 2016 to 2020 while a descriptive cross-sectional study design was used to generate information on the level of knowledge and practices towards TB prevention.
Results:
Out of 4950 presumptive cases of TB (all forms), 469 (9.5%) were placed on TB treatment. The highest prevalence was in 2016 (2.9%) and the lowest in 2019 (1.8%). The majority (65.3%, n = 186) of respondents had adequate knowledge of TB while 143 (57.1%) demonstrated adequate practices in TB prevention. There was a positive correlation between knowledge and practice towards TB prevention (ɼ2 = 29.47, p = 0.001).
Conclusion:
The prevalence of TB (2016-2020) was 9.5%. About one-third of respondents had inadequate knowledge and practices in TB prevention. Sensitization and intensified case finding in favor of TB in this community is encouraged.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
