The article "Effectiveness of one dose of oral cholera vaccine in response to an outbreak: a case-cohort study" investigates whether a single dose of the Shanchol oral cholera vaccine can provide e
...
ffective protection during an outbreak. Conducted in Juba, South Sudan, in 2015, the study involved a case-cohort approach, analyzing vaccination status and disease outcomes.
Findings showed that a single dose was 80.2% effective in preventing medically attended cholera cases, increasing to 87.3% after adjustments for confounding factors. These results suggest that a single-dose strategy can be an effective emergency response, particularly in settings with limited vaccine supply and high mobility of affected populations. The study supports using a single-dose approach during outbreaks when a two-dose regimen is logistically challenging.

Interim guidance, 6 October 2021
Direct detection of SARS-CoV-2 viral proteins (antigens) in nasal swabs and other respiratory secretions using lateral flow immunoassays (also known as rapid diagnostic tests, RDTs) offers a faster and less expensive method to test for SARS-CoV-2 than the reference

method, nucleic acid amplification tests (NAATs). This interim guidance offers recommendations on the priority uses of antigen-detecting rapid diagnostic tests (Ag-RDTs) in specific populations and settings, including (i) for primary case detection in symptomatic individuals suspected to be infected and asymptomatic individuals at high risk of COVID-19, (ii) for contact tracing, (iii) during outbreak investigations and (iv) to monitor trends of disease incidence in communities. Ag-RDTs meeting minimum performance requirements can be used outside of clinical and laboratory settings, including in communities, by trained operators in accordance with instructions. The guidance additionally provides recommendations on implementation, product selection and storage.

The provision of safe and efficacious blood and blood components for transfusion or manufacturing use involves a number of processes, from the selection of blood donors and the collection, processing and testing of blood donations to the testing of patient samples, the issue of compatible blood and
...
its administration to the patient. There is a risk of error in each process in this “transfusion chain” and a failure at any of these stages can have serious implications for the recipients of blood and blood products. Thus, while blood transfusion can be life-saving, there are associated risks, particularly the transmission of bloodborne infections.
Screening for transfusion-transmissible infections (TTIs) to exclude blood donations at risk of transmitting infection from donors to recipients is a critical part of the process of ensuring that transfusion is as safe as possible. Effective screening for evidence of the presence of the most common and dangerous TTIs can reduce the risk of transmission to very low levels. more

Interim guidance, 26 October 2021
This interim guidance has been developed on the basis of the advice issued by the Strategic Advisory Group of Experts (SAGE) on Immunization at its meeting on 5 October 2021.
SAGE said moderately and severely immunocompromised persons should be offered an addition
...
al dose of all WHO approved vaccines “since these individuals are less likely to respond adequately to vaccination following a standard primary vaccine series and are at high risk of severe COVID-19 disease.”
People aged 60 and older who received the Sinovac and Sinopharm vaccines should get a third dose too, the experts added, though use of other vaccines may also be considered depending on supply and access.
“When implementing this recommendation, countries should initially aim at maximizing 2-dose coverage in that population, and thereafter administer the third dose, starting in the oldest age groups”, they said.
SAGE has also reviewed a vaccine developed by Indian company Bharat Biotech and will issue a policy recommendation after WHO greenlights it for emergency use.

This brief advocacy document highlights the burden, risks and prevention of injuries and violence, which took the lives of 4.4 million people in 2019 and constitute 8% of all deaths. Among the injury-related causes of death include road traffic crashes, drowning, falls, burns, poisoning and violence
...
against oneself or others. For people age 5-29 years, three of the top five causes of death are injury-related, including road traffic injuries, homicide, and suicide. Injuries and violence are not evenly distributed across or within countries – some people are more vulnerable than others depending on the conditions in which they are born, grow, work, live and age; in general, being young, male and of low socioeconomic status all increase the risk of injury. This document, aimed at public health professionals; injury prevention researchers, practitioners and advocates; and donors, draws attention to specific strategies based on sound scientific evidence that are effective and cost-effective at preventing injuries and violence; it is critical that these strategies are more widely implemented.

The Infection prevention and control in the context of coronavirus disease 2019 (COVID-19): a living guideline consolidates technical guidance developed and published during the COVID-19 pandemic into evidence-informed recommendations for infection prevention and control (IPC). This living guideline
...
is available both online and PDF.
**This version of the living guideline (version 5.0) **includes the following seven revised statements for the prevention, identification and management of SARS-CoV-2 infections among health and care workers:
a good practice statement on national and subnational testing strategies;
a good practice statement on passive syndromic surveillance of health and care workers;
a good practice statement on prioritizing health and care workers for SARS-CoV-2 testing;
a good practice statement on protocols for reporting and managing health and care worker exposures;
a good practice statement to limit in-person work of health and care workers with active SARS-CoV-2 infections;
a statement on high-risk exposures and quarantine; and,
a conditional recommendation on the duration of isolation for health and care workers.
Understanding the updated section
Prevention of infections in the health care setting includes a multi-pronged and multi-factorial approach that includes IPC and occupational health and safety measures and adherence to Public Health and Social Measures in the community by the health workforce. The underlying infection prevention and control strategy of this section is the notion that early identification of symptomatic cases, testing and quarantining/isolating health and care workers decreases the risk of nosocomial infection to patients and to other health and care workers.

Prompt, effective antimalarial treatment, and supportive care can substantially reduce the rate of mortality from severe malaria. However, many children in malaria-endemic countries do not have access to health facilities or a qualified
...
health care provider and do not receive the necessary care in a timely fashion. Without rapid detection of danger signs and access to effective treatment, including pre-referral treatment that can be administered in the community level, many of these children with severe malaria die.
In situations where there is no immediate access to a health care facility, WHO recommends the administration of a standard dose of an effective antimalarial medicine as pre-referral treatment before referral to a facility at which complete treatment can be administered.
Rectal artesunate is the WHO-recommended pre-referral intervention in situations where artesunate injection are not feasible for children under the age of 6 years with suspected severe malaria. The intervention reduces the risk of death or permanent disability by up to 50% provided the child is referred to a health facility at which complete treatment can be administered.
This field guide is aimed at supporting the effective deployment of RAS as pre-referral treatment of suspected severe malaria in line with the WHO malaria guidelines.

ons.
These Guidelines, specifically tailored to small water supplies, build on over 60 years of guidance by the World Health Organization (WHO) on drinking-water quality and safety. They focus on establishing drinking-water quality regulations and standards that are health based and context appropriate; on proactively managing risks through water safety planning and sanitary inspections; and on carrying out independent surveillance. The guidance is intended primarily for decision-makers at national and subnational levels with responsibility for developing regulatory frameworks and support programmes related to these activities. Other stakeholders involved in water service provision will also benefit from the guidance in this document.
Designed to be practical and accessible, these Guidelines offer clear guidance that is rooted in the principle of progressive improvement. State-of-the-art recommendations and implementation guidance are provided, drawn from a comprehensive evidence review and established good practices. Additionally, case examples are provided from countries and areas around the world to demonstrate how the guidance in this publication has been implemented in practice in a wide variety of contexts.
Together with WHO’s 2024 Sanitary inspection packages – a supporting tool for the Guidelines for drinking-water quality: small water supplies, these Guidelines update and supersede WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. Key changes to this updated publication include a greater focus on preventive risk management and a broader range of small water supplies covered, including those managed by households, communities and professional entities.
