Yaws is among the lesser well known of the neglected diseases, and still it was one of the first targeted by the WHO for eradication. A control programme in the 1950s and 1960s reduced the prevalence by more than 95%. Unfortunately, the disease re-emerged in the 70s, and in 2012, the Morges strategy was developed by the WHO for eradication until 2020. It uses initial mass treatment and biannual resurveys.
Two articles on Yaws were published in the Lancet Global Health (epub on May 30).
This article, titled 'Progress in treatment and diagnosis of yaws: hope for eradication?' by Lola Stamm gives an interesting overview on diagnosis and treatment of Yaws, an endemic treponematose. In the same issue, the sensitivity of the DPP assay for syphilis diagnosis when used for active yaws is reviewed in this article by Telek Ayove et al. titled 'Sensitivity and specificity of a rapid point-of-care test for active yaws: a comparative study'. It is concluded that it is accurate for identification of antibodies in patients with yaws and avoids the need for laboratory support. Its ease of use in comparison with the currently implemented RPR test could be of advantage in yaws eradication activities.
