HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.

Avec l’essor des traitements antirétroviraux (TAR) à base de dolutégravir (DTG) pour soigner les personnes vivant avec
le VIH dans le monde, il est important d’estimer la vitesse à laquelle la résistance acquise au DTG apparaît dans les
populations sous TAR. Bien que la résistance au DT...G ne soit pas apparue dans les populations naïves aux TAR incapables
de supprimer la charge virale dans les essais cliniques, certains éléments portent à croire que la résistance au
DTG peut émerger chez les personnes suivant des schémas thérapeutiques incluant le DTG. L’OMS recommande aux
pays qui étendent les TAR incluant le DTG d’accompagner ce déploiement d’une surveillance en routine de la pharmacorésistance

These guidelines provide a recommendation on iodine thyroid blocking (ITB), via oral administration of stable iodine, as an urgent protective action in responding to a nuclear accident. This recommendation aims to support emergency planners, policy makers, public health specialists, clinicians and o...ther relevant stakeholders, in order to strengthen public health preparedness for radiation emergencies in WHO Member States as required by the International Health Regulations (IHR) and in line with the international safety standards (GSR Part 7). The scope of the guidelines is confined to public health aspects of planning and implementation of ITB before and during a radiation emergency, such as dosage and timing of ITB administration, adverse effects of stable iodine, its packaging, storage, and distribution.
These guidelines supersede the 1999 WHO Guidelines for Iodine Prophylaxis following Nuclear Accidents.

Notable progress has also been made on other key health indicators such as reducing maternal, infant and child deaths and malnutrition, increasing immunization coverage, eliminating infectious diseases such as polio and reducing the incidence of malaria, tuberculosis and diarrhoeal diseases.
But ...despite such substantial progress, the country now faces new and emerging new challenges such as the rising burden of noncommunicable diseases, increased risks associated with disasters, environmental threats and health emergencies during disease outbreaks including the COVID-19 pandemic that is a serious public health threat to Bangladesh. To establish a resilience system for future potential pandemics, the national capacity for emergency preparedness and early response to health emergencies needs to be bolstered considerably.

Cholera is an acute gastrointestinal infection caused by the bacterium Vibrio Cholerae serogroup O1 or O139, and is often linked to unsafe drinking water, lack of proper sanitation and personal hygiene. It adversely affects mostly the poor and vulnerable populations in countries, which are already d...eprived of proper health facilities and conducive environmental conditions. The disease spreads through oro-fecal transmission by the ingestion of contaminated food or water or by person-to-person contact. It has a short incubation period of 2 hours to 5 days and the number of affected cases can rapidly increase across large regions. Cholera is a significant threat to global public health leading to an estimated 3-5 million cases per year worldwide, with an annual toll of 100,000 deaths. The disease was first reported in 1817 from the Ganges Delta of India and since then the ongoing 7th pandemic has emerged from Indonesia, reached Africa in 1970 and Somalia happens to be one of the early affected countries. Over the past few decades,
Somalia has witnessed the occurrence of repeated AWD/Cholera disease outbreaks that have caused high morbidity and mortality across the country.

These consolidated guidelines on HIV testing services (HTS) bring together existing and new guidance on HTS across different settings and populations.
The World Health Organization (WHO) first released consolidated guidelines on HTS in 2015, in response to requests from Member States, national pr...ogramme managers and health workers for support to achieve the United Nations (UN) 90–90–90 global HIV targets – and specifically the first target of diagnosing 90% of all people with HIV. In 2016, based on new evidence, WHO released a supplement to address important new HIV testing approaches – HIV self-testing (HIVST) and provider-assisted referral.
Since the release of 2015 and 2016 HTS guidelines, new issues and more evidence have emerged. To address this, WHO has updated guidance on HIV testing services. In this guideline, WHO updates recommendation on HIVST and provides new recommendations on social network-based HIV testing approaches and western blotting (see box, next page). This guideline seeks to provide support to Member States, programme managers, health workers and other stakeholders seeking to achieve national and international goals to end the HIV epidemic as a public health threat by 2030.
These guidelines also provide operational guidance on HTS demand creation and messaging; implementation considerations for priority populations; HIV testing strategies for diagnosis HIV; optimizing the use of dual HIV/syphilis rapid diagnostic tests; and considerations for strategic planning and rationalizing resources such as optimal time points for maternal retesting
