The extent of this problem is difficult to measure. Standard WHO injection safety assessment protocols used in the 2003 national injection safety assessment in Cameroon are problematic because health workers often behave differently under the observation of visitors. The main objective of this study is to assess the extent of unsafe injection equipment reuse and potential for blood-borne virus transmission in Cameroon. This can be done by probing for misconceptions about injection safety that explain reuse without sterilization. These misconceptions concern useless precautions against cross-contamination . indirect reuse of injection equipment. To investigate whether a shortage of supply explains unsafe reuse we compared our survey data against records of purchases. Methods All health workers at public hospitals in two health districts in the Northwest Province of Cameroon were interviewed about their own injection practices. Injection equipment supply purchase records documented for January to December 2009 were compared with self-reported rates of syringe reuse. The number of HIV HBV and HCV infections that result from unsafe medical injections in these health districts is estimated from the frequency of unsafe reuse the number of injections performed the probability that reused injection equipment had just been used on an infected patient the size of the susceptible population and the transmission efficiency of each virus in an injection.
