In 2006, Ghana ranked second in Guinea worm disease (GWD) incidence and reported a previously undocumented 20% prevalence of worm breakage. A prospective study was conducted in 2007 to validate and describe worm breakage and determinants. Among 221 patients with known outcomes, the worm breakage rate observed was 46%. After controlling for demographics, worm and wound presentation, and treatment course and provision, worm breakage was associated with narrow-diameter worms (< 2 mm) (adjusted odds ratio [AOR] 2.79; 95% confidence interval [CI] = 1.03-7.53). Protective factors against worm breakage included antibiotic ointment use (AOR 0.31; 95% CI = 0.14-0.70), bandage protocol compliance (AOR: 0.38; 95% CI = 0.16-0.89), intact bandages (AOR 0.27; 95% CI = 0.09-0.82), and bloody compared with dry wounds (AOR 0.09; 95% CI = 0.01-0.7). The high worm breakage rate observed warrants improvement in case management and patient care. Adherence to established treatment protocols should be facilitated through improved provider training and supervision to reduce the disabling consequences of broken worms.

Condom promotion remains a key component of HIV prevention programs, complimenting recent successes in biomedical HIV prevention. Although condom use has increased in much of East Africa, it remains substantially below optimal levels. Negative rumors about condoms have been documented in East Africa, yet the prevalence and effects of belief in the negative rumors have not been explored. This study evaluated levels of belief in negative rumors about condoms, developed a Negative Condom Beliefs Scale, and assessed its accuracy in predicting willingness to use condoms. A cross-sectional, cluster survey (n = 370) was conducted representing adults in two rural districts in Northern Tanzania in 2008. Item agreement ranged from 35 to 53% for the following rumors regarding condoms: causing cancer, having holes, containing HIV, having worms, and the worms causing HIV. Items loaded on a single latent factor and had high internal consistency and convergent validity. In a multivariate model, negative condom score (AOR = 0.67, 95% CI = 0.6, 0.8) was the strongest single predictor of willingness to use condoms, followed by greater perceived anonymity in acquiring condoms (AOR = 4.36, 95% CI = 2.2, 8.6) and higher condom self-efficacy (AOR = 4.24, 95% CI = 2.0, 8.9). Our findings indicate high levels of subscription to negative beliefs about condoms, with two out of three respondents affirming belief in at least one negative condom rumor. This study highlights the relation between condom rumor beliefs and willingness to use condoms, and indicates avenues for future research and means for improving the design of HIV prevention programs.
