Abstract

Background: TB cases detected in Nigeria are still far below WHO target of 70% despite adoption of DOTS strategy since 1994 with subsequent expansion of treatment to primary health centers where diagnosis and treatment is done mainly by general health care workers. However, the extent of adherence to standard guideline by such cadre is unknown.

Knowledge on TB causation and mode of transmission was found to be relatively high as about 200 (71.4%) correctly describe TB as a microbial infection and about 216 (77.1%) knew airborne route as mode of transmission. When asked to define DOTS, 62.5% of the health workers gave a correct definition with only 109 (38.9%) abled to list the 4 main drugs given during intensive phase of treatment. In addition, about half of the respondents (52.5%) knew that treatment last for 8 months.
