The World Health Organization (WHO) endorses the use of population-based prevalence surveys for estimating the prevalence of trachoma. In general, the prevalence of TF in children aged 1–9 years and the prevalence of TT in adults aged ≥ 15 years are measured at the same time in any district bein...g surveyed. This was the approach of the Global Trachoma Mapping Project, which undertook baseline surveys in > 1500 districts worldwide in order to provide the data required to start interventions where needed.
The survey design recommended by WHO is a two-stage cluster random sample survey, which uses probability proportional to size sampling to select 20–30 villages, and random, systematic or quasi-random sampling to select 25–30 households in each of those villages. In most surveys, everyone aged ≥ 1 year living in selected households is examined.

In case of resistance to rifampicin, fluoroquinolones become the preferred category of second-line drugs. Unfortunately, quinolone-resistant strains of Mycobacterium leprae have also been reported in several countries, probably due to the extensive use of quinolones for treating several types of inf...ections. Clofazimine resistance is still rare but this antimicrobial cannot be given alone

Over the reporting period, economic actors continued to carry out their activities with little regard for their impacts on the livelihoods of the communities living in the surrounding areas. In Doo Tha Htoo (Thaton) District, cold dust from a Tatmadaw-run cement factory contaminated nearby waterways... during the rainy season. As a result, civilians from at least 15 villages faced water shortages. In Mu Traw (Hpapun) and Kler Lwee Htoo districts, gold mining activities damaged forests and polluted water and soils in several village tracts. In both cases, the economic actors involved failed to secure the free, prior and informed consent (FPIC) of the local population, and did not compensate the affected communities for the damage caused.

Molecular methods for antimicrobial resistance (AMR)diagnostics to enhance the Global Antimicrobial Resistance Surveillance System
Whole-genome sequencing (WGS) provides a vast amount of information and the highest possible resolution for pathogen subtyping. The application of WGS for global surveillance can provide information on the early emergence and spread of AMR and further inform timely policy development on AMR control.... Sequencing data emanating from AMR surveillance may provide key information to guide the development of rapid diagnostic tools for better and more rapid characterization of AMR, and thus complement phenotypic methods. This document addresses the applications of WGS for AMR surveillance, including the benefits and limitations of current WGS technologies

Guidance for addressing a global infodemic and fostering demand for immunization
December 2020
Misinformation threatens the success of vaccination programs across the world. This guide aims to help organizations to address the global infodemic through the development of strategic and well-coordina...ted national action plans to rapidly counter vaccine misinformation and build demand for vaccination that are informed by social listening.

Antimicrobial resistance (AMR) surveillance plays an important role in the early detection of resistant strains of public health importance and prompt response to outbreaks in hospitals and the community. Surveillance findings are needed to inform medical practice, antibiotic stewardship, and policy... and interventions to combat AMR. Appropriate use of antimicrobials, informed by surveillance, improves patients’ treatment outcomes and reduces the emergence and spread of AMR. This protocol describes the steps and procedures to establish/enhance AMR surveillance in Latin America and the Caribbean.

The purpose of this TPP is to communicate the minimum and ideal characteristics desired to meet the need for discriminating low levels of risk for transmission, i.e. targeted prevalence thresholds in the surveyed areas. An in vitro diagnostic test is needed for the detection of analyte(s) specific t...o Wuchereria bancrofti, Brugia malayi, and Brugia timori to aid in the surveillance of defined geographic areas as to whether infection and/or transmission potential has increased (recrudescence) or decreased (elimination of transmission).

Epidemic meningitis is a major public health challenge in the African 'meningitis belt', an area that extends from Senegal to Ethiopia with an estimated total population of 500 million. Since 2002, the World Health Organization (WHO), in collaboration with its collaborating centres for meningitis, h...as progressively supported countries in implementing a strategy of ES for meningitis. The strategy is the recommended standard for all countries of the Belt and it is now actively being implemented at different levels in all countries.

39 examples of field practices, and learnings from 20 countries, for all phases of humanitarian response. The report shows that deliberate and proactive action is required to ensure that persons with disabilities from all constituencies are systematically included and meaningfully participate in DRR... and humanitarian preparedness, response and recovery. It draws lessons from field practices, but does not provide technical guidance. The newly published IASC Guidelines are the reference document to seek in-depth theoretical and technical information.

PLoS Negl Trop Dis 5(6): e1187. doi:10.1371/journal.pntd.0001187. Buruli ulcer (BU), caused by Mycobacterium ulcerans infection, is a debilitating disease of the skin and underlying tissue which starts as a painless nodule, oedema or plaque and could develop into painful and massive ulcers if left u...ntreated. Using a combination of quantitative and qualitative methods, the study assessed the effectiveness of the BUPaT programme to improve early detection and management of BU in an endemic area in Ghana.

Recency assays use one or more biomarkers to identify whether HIV infection in a person is recent (usually within a year or less) or longstanding. Recency assays have been used to estimate incidence in representative cross-sectional surveys and in epidemiological studies to better understand the pat...terns and distributions of new and longstanding HIV infections.
This technical guidance outlines best practices regarding the appropriate use of HIV recency assays for surveillance purposes and updates 2011 technical guidance from the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) on the use of HIV recency assays.
