Benchmarking the Cost per Person of Mass Treatment for Selected Neglected Tropical Diseases: An Approach Based on Literature Review and Meta-regression with Web-Based Software Application
DiscussionThe available evidence confirms that mass treatment offers a low cost public health intervention on the path towards universal health coverage. However, more costing studies focussed on elimination are needed. Unit cost benchmarks can help in monitoring value for money in programme plans, budgets and accounts, or in setting a reasonable pay-out for results-based financing mechanisms.

WHO Declares India Free of Yaws and Maternal and Neonatal Tetanus
India was recognized by the World Health Organization in July with official certificates of elimination for 2 neglected tropical diseases —yaws and maternal and neonatal tetanushttp://bit.ly/29VXMeD. These achievements, which were carried out through the existing health system and health workforce in India, illustrate the nation ’s commitment to their elimination and serve as an example to other countries.

Opportunities for Integrated Control of Neglected Tropical Diseases That Affect the Skin.
Abstract Many neglected tropical diseases (NTDs) affect the skin, causing considerable disability, stigma, and exacerbation of poverty. However, there has been relatively little investment into laboratory research, epidemiology, diagnostic tools or management strategies to control tropical skin disease. Integration may advance the control of skin disease across a range of domains, including mapping, diagnosis, clinical management, and community control measures such as mass drug administration. Examples of successful integration strategies include programs targeting scabies, impetigo, yaws, and diseases ca...

Prevalence of Active and Latent Yaws in the Solomon Islands 18 Months after Azithromycin Mass Drug Administration for Trachoma
We examined children aged 1 –14 years and took blood and lesion samples for yaws diagnosis using theTreponema pallidum particle agglutination assay (TPPA) and the non-treponemal Rapid Plasma Reagin (RPR) test. ResultsA total of 1,284 children were enrolled in the study. Amongst children aged 5 –14 years, 223 had a positive TPPA (27.5%, 95% CI 13.6–47.7%). The TPPA seroprevalence amongst this age group did not differ significantly from either our pre-mass treatment survey or our initial follow-up survey. Thirty-five children had positive TPPA and positive RPR (4.3%, 95% CI 2.1–8.7%), and this did not differ signific...

Metaanalysis of the Performance of a Combined Treponemal and Nontreponemal Rapid Diagnostic Test for Syphilis and Yaws
Conclusions. The RDT has good sensitivity and specificity of the treponemal and nontreponemal components both in cases of suspected syphilis and yaws, although the sensitivity is decreased at lower antibody titers. (Source: Clinical Infectious Diseases)

Yaws: towards the WHO eradication target
In 2012 WHO declared a target to eradicate yaws by 2020. The cornerstone of this strategy is community mass treatment with azithromycin. Initial studies suggest this is a very effective tool that may be capable of interrupting transmission. Alongside this there has been progress in the development and validation of diagnostic tests for yaws. Several new challenges have also emerged, in particular, evidence that Haemophilus ducreyi can cause phenotypically similar ulcers in yaws endemic communities, and evidence for a possible non-human primate reservoir. The 2020 eradication target remains ambitious and more challenges sho...

The Prevalence of Scabies and Impetigo in the Solomon Islands: A Population-Based Survey
Conclusions and Significance Scabies and impetigo are very common in the rural Western Province of the Solomon Islands. Scabies infestation is strongly associated with impetigo. Community control strategies for scabies may reduce the burden of both conditions and their downstream complications. (Source: PLoS Neglected Tropical Diseases)

Evaluation of Multiplex-Based Antibody Testing for Use in Large-Scale Surveillance for Yaws: a Comparative Study [Epidemiology]
WHO has targeted yaws for global eradication by 2020. The program goals are to interrupt the transmission in countries where yaws is endemic and to certify countries as yaws free where yaws was endemic in the past. No new rapid plasmin reagin (RPR) seroreactivity in young children is required for certification of elimination at a country level. We sought to evaluate whether antibody responses to specific treponemal antigens measured in a high-throughput multiplex bead array (MBA) assay differentiate past versus current infection and whether a nontreponemal lipoidal antigen test can be incorporated into the MBA. Serum and d...

A Sero-epidemiological Approach to Explore Transmission of Mycobacterium ulcerans
by Kobina Assan Ampah, Beatrice Nickel, Prince Asare, Amanda Ross, Daniel De-Graft, Sarah Kerber, Ralf Spallek, Mahavir Singh, Gerd Pluschke, Dorothy Yeboah-Manu, Katharina Röltgen The debilitating skin disease Buruli ulcer (BU) is caused by infection with Mycobacterium ulcerans. While various hypotheses on potential reservoirs and vectors of M. ulcerans exist, the mode of transmission has remained unclear. Epidemiological studies have indicated that children below the age of four are less exposed to the pathogen and at lower risk of developing BU than older children. In the present study we compared the age at which chi...

Haemophilus ducreyi: from sexually transmitted infection to skin ulcer pathogen
This article provides an overview of the biology, epidemiology, clinical features, diagnostic tests, and treatment of Haemophilus ducreyi infection, with special reference to the decline of chancroid and the recent emergence of H. ducreyi as a pathogen responsible for chronic limb ulceration clinically similar to yaws. Recent findings: Chancroid has declined in importance as a sexually transmitted infection in most countries where it was previously endemic. Chancroid may be caused by either class I or class II H. ducreyi isolates; these two classes diverged from each other approximately 1.95 million years ago. H. ducreyi h...

Diagnosis and evaluation of causative factors for the presence of endemic treponemal disease in a Japanese sub-tropical island population from the Tokugawa period
We present a description and differential diagnosis of pathological lesions observed on skeletal elements found during surface surveys of the Nagabaka site on Miyako-jima Island, Japan. The Nagabaka site served as a bone depository during the Early Modern period (c. AD 1600–1870). We evaluated remains via macroscopic inspection to classify infectious lesions according to criteria in Weston (2008). We also obtained CT scans of three bone elements for more extensive lesion analysis and carried out a differential diagnosis utilizing paleopathological literature. Subsequent investigation yielded convincing evidence of trepon...
