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.

Cervical intraepithelial neoplasia (CIN) is a premalignant lesion that may exist at any one of three stages: CIN1, CIN2, or CIN3. If left untreated, CIN2 or CIN3 (collectively referred to as CIN2+) can progress to cervical cancer. Instead of screening and diagnosis by the standard sequence of cytolo...gy, colposcopy, biopsy, and histological confirmation of CIN, an alternative method is to use a ‘screen-and-treat’ approach in which the treatment decision is based on a screening test and treatment is provided soon or, ideally, immediately after a positive screening test. This guideline provides recommendations for strategies for a screen-and-treat programme

The WHO Toolkit for the care and support of people affected by complications associated with Zika virus has been developed to serve as a model guide, with the goal of enhancing country preparedness for Zika virus outbreaks. The toolkit is intended to provide a systems approach involving public heal...th planners and managers so that the necessary infrastructure and resources can be identified and incorporated as needed, as well as technical and practical guidance for health care professionals and community workers.
The toolkit includes three manuals to provide countries with tools to effectively recognize people affected by Zika virus and deliver comprehensive care and support:
Manual for public health planners and managers
Manual for health care professionals
Manual for community workers

Following review of the latest evidence, WHO recommends that TB-LAMP can be used as a replacement for microscopy for the diagnosis of pulmonary TB in adults with signs and symptoms of TB. It can also be considered as a follow-on test to microscopy in adults with signs and symptoms of pulmonary TB, e...specially when further testing of sputum smear-negative specimens is necessary.

The report offers 20 top recommendations for getting ahead of future outbreaks in Yemen and similarly complex humanitarian settings.
In 2015, Yemen was declared a Level 3 emergency by the UN, kicking into gear the highest level of humanitarian support. A massive cholera outbreak followed, leading t...o 1 million suspected cases in 2 waves from September 2016-July 2018.
“We largely know ‘what to do’ to control cholera, but context-specific practices on ‘how to do it’ in order to surmount challenges to coordination, logistics, insecurity, access and politics remain needed,” the report states.
While the response improved between the 2 waves, there were gaps. For one, Yemen’s history of cholera should have triggered a heavy focus on pre-planning for an epidemic, such as stockpiling supplies and doubling down on community-based surveillance, the report fou

The objectives of these guidelines are to provide recommendations outlining a public health approach to managing people presenting with advanced HIV disease, and to provide guidance on the timing of initiation of antiretroviral therapy (ART) for all people living with HIV.
WHO recommends that a... package of screening, prophylaxis, rapid ART initiation and intensified adherence interventions be offered to everyone living with HIV presenting with advanced disease.
WHO strongly recommends that rapid ART initiation should be offered to people living with HIV following confirmed diagnosis and clinical assessment. Rapid initiation of ART is defined as within seven days of HIV diagnosis. WHO further strongly recommends ART initiation on the same day as HIV diagnosis based on the person’s willingness and readiness to start ART immediately, unless there are clinical reasons to delay treatment.

Sepsis contributes significantly to preventable mortality and is the final common pathway to death for severe infectious diseases; it can also arise as a complication of injuries and non-communicable diseases.
Meeting Report 27-29 October 2020
The overall goal of the meeting was to discuss recent changes in treatment regimens and diagnostics for drug-resistant TB and to determine how these impact on the definition of XDR-TB, with a view to revising this definition. The pre-existing definition of XDR-TB w...as formulated in 2006 at a meeting of the Global Taskforce on XDR-TB, convened by WHO, and has been in use for clinical and surveillance purposes, since this time.

Weekly epidemiological record; Relevé épidémiologique hebdomadaire 10 SEPTEMBER 2021, 96th YEAR / 10 SEPTEMBRE 2021, 96e ANNÉE No 36, 2021, 96, 421–444
The COVID-19 pandemic arrived in an evolving epidemiological context where some countries are experiencing a progressive decrease in HIV positivity in their testing programme as they are moving closer to the first 95 target. Distinguishing changes in HIV testing services due to the COVID-19 pandemic... from those resulting from evolving HIV testing strategies is crucial for adapting services and helping countries define their strategic mix of testing options moving forward. There is a need to focus, prioritize and plan for strategic efforts to prevent going further off the track toward achieving global targets and goals.
To support these efforts, WHO in partnership with ministries of health conducted an in-depth analysis of HIV testing services and antiretroviral therapy (ART) initiation prior to and during reported COVID-19 disruptions. Additional publicly available Global Fund and PEPFAR data was also reviewed and analysed. This analysis, and coordination with ministries of health, identified key service delivery adaptations utilized during COVID-19-related disruptions and formed the basis of this strategic guide.
This document focuses on current country needs, as well as plans for prioritization and potential surge support needs in the event of future disruptions. Although the data and implications are specific to sub-Saharan Africa, key principles and lessons can be applied elsewhere.

TDR (Tropical Disease Research) Annual Report 2018
WHO has published the first-ever guidance on the clinical management of diphtheria. The only previously available guidance was an operational protocol. The new guidance followed the rigorous process for developing guidance at WHO.
It addresses the use of Diphtheria Antitoxin (DAT) in the treatmen...t of diphtheria. There is a worldwide shortage of DAT and evidence based recommendations on the use of DAT were requested by many Member States.
The guidance also includes new recommendations on antibiotics. In patients with suspected or confirmed diphtheria, WHO recommends using macrolide antibiotics (azithromycin, erythromycin) rather than penicillin antibiotics.
This clinical practice guideline has been rapidly developed recognizing the global increase in diphtheria outbreaks. Outbreaks of diphtheria in Nigeria, Guinea and neighbouring countries in 2023 have highlighted the urgent need for evidence-based clinical practice guidelines for the treatment of diphtheria. Given the sporadic nature of outbreaks, many clinicians in the affected regions have never managed acute diphtheria and its related complications. Diphtheria remains a neglected disease and vaccination is the top priority. At the same time, for patients with diphtheria, access to antibiotics, DAT and supportive care can be lifesaving.
