During a survey of yaws prevalence in the Solomon Islands, we collected samples from skin ulcers of 41 children. Using PCR, we identified Haemophilus ducreyi infection in 13 (32%) children. PCR-positive and PCR-negative ulcers were phenotypically indistinguishable. Emergence of H. ducreyi as a cause of nongenital ulcers may affect the World Health(More)
Yaws is a non-venereal treponemal infection caused by Treponema pallidum ssp. pertenue. The WHO has launched a worldwide control programme, which aims to eradicate yaws by 2020. The development of a rapid diagnostic test (RDT) for serological diagnosis in the isolated communities affected by yaws is a key requirement for the successful implementation of the(More)
BACKGROUND Community mass treatment with 30 mg/kg azithromycin is central to the new WHO strategy for eradicating yaws. Both yaws and trachoma--which is earmarked for elimination by 2020 using a strategy that includes mass treatment with 20 mg/kg azithromycin--are endemic in the Pacific, raising the possibility of an integrated approach to disease control.(More)
BACKGROUND Trachoma is endemic in several Pacific Island states. Recent surveys across the Solomon Islands indicated that whilst trachomatous inflammation-follicular (TF) was present at levels warranting intervention, the prevalence of trachomatous trichiasis (TT) was low. We set out to determine the relationship between chlamydial infection and trachoma in(More)
Yaws, a non-venereal treponemal disease, is targeted for eradication by 2020 but accurate epidemiological data to guide control programs remain sparse. The Solomon Islands reports the second highest number of cases of yaws worldwide. We conducted a cluster randomized survey of yaws in two provinces of the Solomon Islands. One thousand four hundred and(More)
OBJECTIVES This study sought to determine the prevalence of common bacterial sexually transmitted infections, including Chlamydia trachomatis and Neisseria gonorrhoeae, in women attending clinics in the Solomon Islands. METHODS We conducted a sexual health survey among women attending three nurse-led community outpatient clinics in August 2014, to(More)
OBJECTIVES Chlamydia trachomatis is the most common bacterial sexually transmitted infection and is frequently asymptomatic; ocular C. trachomatis strains cause trachoma. Mass drug administration (MDA) of azithromycin for trachoma might also reduce the prevalence of genital C. trachomatis. In a survey conducted in the Solomon Islands in 2014, prior to MDA,(More)
PURPOSE We sought to complete the baseline trachoma map of the Solomon Islands by establishing prevalences of active trachoma and trichiasis in the provinces of Choiseul, Western, Rennell-Bellona, and Temotu. METHODS Using the standardized methodology developed for the Global Trachoma Mapping Project, we conducted cross-sectional community-based surveys(More)
