Abstract Background : Tuberculosis (TB) remains a major health problem in Africa and more particularly in sub-Saharan countries such as Cameroon due to its impact on mortality, morbidity and socio-economic repercussions on the population in general, in this case in big cities like Douala. In 2018, the Littoral region in Cameroon recorded more than 5,000 cases of tuberculosis representing a quarter of the total number of TB patients in in the country. The application of measures to control TB infection and the regular surveillance of tuberculosis disease among health workers and at all levels of the health system constitute a public health priority, not only for health and administrative workers, but also for all users. This study assessed the adherence to preventive measures against TB by health workers of the diagnostic and treatment centers in the city of Douala.
