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 Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used.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.

The HIV drug resistance report 2021 summarizes findings from 38 countries that had finalized the surveys by the time of this report and shared data with WHO.
Pretreatment HIVDR to non-nucleoside reverse-transcriptase inhibitors (NNRTI) can affect more than 10% of adults starting therapy and is fo...und up to 3 times more often in people who had previous exposure to antiretroviral drugs. In addition, nearly half of infants newly diagnosed with HIV has HIVDR to NNRTI before initiating treatment.The high levels of observed NNRTI pretreatment HIVDR among emphasize the need to fast-track the transition to WHO-recommended dolutegravir-based ART.

GLOBAL EDUCATION MONITORING REPORT 2017/8
When setting national drinking-water quality regulations and standards, many countries consider the WHO Guidelines for drinking-water quality (GDWQ). To better understand the extent to which the GDWQ are used and reflected in these standards, this global review summarizes information from 104... countries and territories on values specified in national drinking-water quality standards for aesthetic, chemical, microbiological and radiological parameters.
The information provided will support regulatory agencies and other key stakeholders to access and compare data when setting or revising national drinking-water quality regulations and standards.

The report reveals that good IPC programmes can reduce health care infections by 70 %. oday, out of every 100 patients in acute-care hospitals, seven patients in high-income countries and 15 patients in low- and middle-income countries will acquire at least one health care-associated infection (HAI)... during their hospital stay. On average, 1 in every 10 affected patients will die from their HAI.
People in intensive care and newborns are particularly at risk. And the report reveals that approximately one in four hospital-treated sepsis cases and almost half of all cases of sepsis with organ dysfunction treated in adult intensive-care units are health care-associated.

Progress in prevention and treatment is faltering around the world, putting millions of people in grave danger. Eastern Europe and central Asia, Latin America, and the Middle East and North Africa have all seen increases in annual HIV infections over several years. In Asia and the Pacific, UNAIDS da...ta now show new HIV infections are rising where they had been falling. Action to tackle the inequalities driving AIDS is urgently required to prevent millions of new HIV infections this decade and to end the AIDS pandemic

Mientras los países se esfuerzan por avanzar hacia los Objetivos de Desarrollo Sostenible (ODS) y lograr la cobertura sanitaria universal, las desigualdades sanitarias provocadas por la discriminación racial y los factores interrelacionados siguen estando omnipresentes. Las desigualdades que sufre...n los pueblos indígenas, los afrodescendientes, los romaníes y otras minorías étnicas son preocupantes a nivel mundial; son injustas, prevenibles y remediables
Los propios sistemas de salud son determinantes importantes de la salud y la equidad sanitaria. Pueden perpetuar las desigualdades sanitarias al reflejar el racismo estructural y las prácticas discriminatorias de la sociedad en general. En este sentido, el racismo sistémico (por ejemplo, relacionado con la ubicación de los servicios o los requisitos para acceder a ellos), los prejuicios implícitos, la práctica clínica mal informada o la discriminación por parte de los profesionales de la salud contribuyen a las desigualdades sanitarias. Ahora bien, los sistemas de salud también pueden convertirse en una de las principales fuerzas para combatir las desigualdades a las que se enfrentan las poblaciones que sufren discriminación racial.
La atención primaria de salud (APS) representa la estrategia esencial que permite reorientar los sistemas de salud y las sociedades para que sean más saludables, equitativos, eficaces y sostenibles. En 2018, al cumplirse el 40.º aniversario de la Declaración de Alma-Ata, la Organización Mundial de la Salud (OMS) y el Fondo de las Naciones Unidas para la Infancia (UNICEF) renovaron el énfasis en la atención primaria de salud con su estrategia sobre la atención primaria de salud en el siglo XXI.
La OMS ha señalado 14 mecanismos estratégicos y operacionales con los que los responsables políticos pueden reforzar la atención primaria de salud. Cada mecanismo dispone de múltiples puntos de partida posibles para emprender acciones específicas dirigidas a combatir la discriminación racial, fomentar la atención de salud intercultural y reducir las desigualdades sanitarias que sufren los pueblos indígenas, los afrodescendientes, los romaníes y otras minorías étnicas
