Taenia saginata is a zoonotic tapeworm that is of economic importance in countries where cattle are kept. The parasite is transmitted from human tapeworm carriers (taeniosis) to bovines (cysticercosis) by excretion of eggs or proglottids containing eggs into the environment via the stool. Bovines ca...n then ingest the eggs through contaminated feed or water. After ingestion, the eggs hatch and release oncospheres in the small intestines, where the oncospheres penetrate the intestinal wall to reach the blood circulation. This distributes them throughout the body, but primarily to muscle tissue, where they develop into cysticerci. For humans to become infected with T. saginata, raw or undercooked bovine meat or offal containing infective cysts must be consumed. Bovine cysticercosis has been associated with various environmental factors related to water sources, such as animals having access to surface water, flooding of pastures and proximity to wastewater sources.

Ношение медицинской маски является одной из профилактических мер, которая может ограничить распространение ряда вирусных инф...кций, в том числе, COVID-19. Однако использования маски как единственного средства недостаточно для обеспечения адекватного уровня защиты, и следует принимать также другие меры. Независимо от применения масок первоочередное значение в профилактике передачи COVID-19 от человека к человеку имеет тщательное соблюдение гигиены рук и других мер ПИИК.

International Perspectives and Future Directions
Safe sanitation is essential for health, from preventing infections to improving and maintaining mental and social
well-being. Lack of adequate sanitation contributes to diarrhoeal diseases, parasitic infections, and undernutrition, as
well as posing significant risks and causing anxiety, especial...ly for women and girls. Achieving universal access to safe
sanitation, which protects health, privacy, and dignity, is a global development goal and a recognized basic human right.

interim guidance, 25 November 2024
This guideline provides updated, evidence-informed guidance on the percentage of total fat in the diet to reduce the risk of unhealthy weight gain.
This guideline is intended for a wide audience involved in the development, design and implementation of policies and programmes in nutrition and pub...lic health. This guideline includes a recommended level of total fat intake which can be used by policy-makers and programme managers to address various aspects of dietary fat in their populations through a range of policy actions and public health interventions.
The guidance in this guideline replaces previous WHO guidance on total fat intake, including that from the 1989 WHO Study Group on Diet, Nutrition and the Prevention of Chronic Diseases and the 2002 Joint WHO/FAO Expert Consultation on Diet, Nutrition and the Prevention of Chronic Diseases. The guidance in this guideline should be considered in the context of that from other WHO guidelines on healthy diets.

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 risk communication and community engagement (RCCE) competency framework is a resource that details the essential behaviours and activities necessary for effective communication and engagement with communities before, during and after public health emergencies. The purpose of this framework is to... establish and promote a common understanding of behavioural competencies and how they should be applied for high-performing and community-centred health emergency programmes. It is intended to support the development of standardized training programmes, professional development and talent acquisition and to enhance the capabilities of public health professionals involved in RCCE. Its goal is to inform the establishment of a skilled, well-trained RCCE workforce that consistently understands and executes the necessary behaviours and activities required to conduct RCCE activities with competence and professionalism.

PEPFAR Malawi’s Country Operational Plan 2022 (COP22) embodies joint priorities from national and subnational dialogues building on the 2020-2025 National Strategic Plan for HIV/AIDS. The interagency team has developed a person-centered, district-tailored and Malawi Population-Based HIV Impact Ass...essment (MPHIA)-informed strategy through extensive engagement with Government of Malawi (GoM) and Civil Society Organizations (CSOs) to sustain HIV epidemic control. At the end of COP21, PEPFAR Malawi was commended for contributing to reaching epidemic control in strong collaboration with GoM and stakeholders including the Global Fund to Fight AIDS, Tuberculosis and Malaria (Global Fund). This includes enrollment of 88% of recipients of care on three or more months of antiretroviral treatment (ART), better outcomes for Malawian children through remarkable efforts in Orphans and Vulnerable Children (OVC) programming and progress made towards reaching men with more intentional and focused programming.
