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.

This document is based on currently available scientific evidence on treatment for drug use disorders and sets out a framework for the implementation of the Standards, in line with principles of public health care. The Standards identify major components and features of effective systems for the tre...atment of drug use disorders. They describe treatment modalities and interventions to match the needs of people at different stages and severities of drug use disorders, in a manner consistent with the treatment of any chronic disease or health condition. The Standards are aspirational, and such, national or local treatment services or systems need not attempt to meet all the standards and recommendations made in this document all at once. However over time, progressive quality improvement, with ‘evidence-based and ethical practice’ as an objective, can and should be expected to achieve better organized, more effective and ethical systems and services for people with drug use disorders.

2nd edition. These guidelines provide guidance on the diagnosis of human immunodeficiency virus (HIV) infection, the use of antiretroviral (ARV) drugs for treating and preventing HIV infection and the care of people living with HIV. They are structured along the continuum of HIV testing, prevention,... treatment and care

The WHO Guidelines on risk reduction of cognitive decline and dementia provide evidence-based recommendations on lifestyle behaviours and interventions to delay or prevent cognitive decline and dementia. These WHO Guidelines are an important tool for health care providers as well as governments, pol...icy-makers and other stakeholders to strengthen their response to the dementia challenge.

In the area of nutrition and HIV, children deserve special attention because of their additional needs to ensure growth and development and their dependency on adults for adequate care. It was therefore proposed to first develop guidelines for children and thereafter consider a similar approach for... other specific groups.
The content of these guidelines acknowledges that wasting and undernutrition in HIV-infected children reflect a series of failures within the health system, the home and community and not just a biological process related to virus and host interactions. In trying to protect the nutritional well-being or reverse the undernutrition experienced by infected children, issues of food insecurity, food quantity and quality as well as absorption and digestion of nutrients are considered. Interventions are proposed that are practical and feasible in resource-poor settings and offer a prospect for clinical improvement.
The guidelines do not cover the feeding of infants 0 to 6 months old, because the specialised care in this age group is already addressed in other WHO guidelines and documents.

Tools and practical guidance for achieving high uptake
To save the lives of mothers and their babies, mitigate complications, and limit the spread of disease, it is critical that recommendations are made on the prevention, treatment, and surveillance of women who are exposed to EVD, acquire EVD during pregnancy or breastfeeding, or survive EVD with ongo...ing pregnancies. These guidelines are the first to provide such recommendations.

These guidelines aim to guide all health care providers in Myanmar, accommodating the situation of different settings in the context of progressive decentralization of HIV services. Notable changes from the previous edition include:
• diagnosis of HIV
• update on the initiation of ART<...br>
• new ARV drugs and regimens
• new recommendation on infant prophylaxis
• PrEP and PEP updates
• updates on co-infections and comorbidities management
It should be noted that these guidelines are meant for the operational level and are adapted and adopted in line with existing Myanmar context.

It is estimated that more than 311 000 women die of cervical
cancer each year. Of these deaths, 91% occur in low- and
middle-income countries. Demographic changes and a lack of
action mean that the number of deaths per year is projected
to reach 460 000 by 2040.
The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

Immunizations are an essential health service that protect susceptible individuals from vaccine-preventable diseases (VPD).2 By providing timely immunizations, individuals and communities remain protected and the likelihood of a VPD outbreak decreases
