Building on the 2021 Interim guidance, this second version and update, incorporates the lessons and feedback from the hepatitis pilots that successfully demonstrated the feasibility of measuring hepatitis B and C impact targets to demonstrate elimination, whilst highlighting challenges caused by hig...h disease burden in some countries, as well as delays in reaching mortality targets due to the long natural history of disease progression to liver cirrhosis and hepatocellular carcinoma.
The path to elimination provides a framework with 3 levels of achievements for which WHO certification is available. Each stepwise progression from bronze to silver to gold tiers will promote an iterative expansion of prevention, diagnosis and treatment services for viral hepatitis services and strengthen measurement systems to support attainment of the 2030 elimination goals.
This updated version also includes changes, clarifications and new guidance on alternative measurement approaches for country validation of elimination. Through the validation process, WHO and partners continue to provide country support for strengthening health system capacity and patient-centred services that respect and protect the human rights of people living with viral hepatitis and ensures meaningful engagement of communities in the national, regional and global viral hepatitis response.

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

This report, published in conjunction with a summary overview of results of rounds 1–8, is the eighth and final report in a series of laboratory-based evaluations of rapid diagnostic tests (RDTs) for malaria. It provides a comparative measure of their performance in a standardized way to distingui...sh between well and poorly performing tests.
These results constitute the laboratory evaluation component of the WHO prequalification process for malaria RDTs and inform the current WHO procurement recommendations. In round 8, 35 RDTs from 17 manufacturers were assessed. For the first time the evaluation included an assessment of product performance against a panel of P. falciparum parasites with pfhrp2/3 gene deletions and therefore not expressing HRP2.

Breaking Barriers is an implementation research project focusing on social and behavioural change. It is conducted in conflict-affected communities in Cameroon. The project explores three innovative, community-based interventions designed to improve health behaviours. This presentation outlines the ...project's context, methodology and implementation process. It also shares qualitative insights and field perspectives, reflecting on key lessons learned for future SBC efforts in fragile settings.

Do no harm, equality, transparency, humanity: values should guide the criminal justice sector’s response to coronavirus
At the time of publishing there were more than 164,000* confirmed cases of COVID- 19, the novel form of Coronavirus, affecting 110 countries wit...h more than 6,470 deaths. In this briefing we assess the current situation of COVID-19 outbreaks and prevention measures in prisons** and wider impacts of responses to governments on people in criminal justice systems. This briefing note argues for action to be taken now and immediately, given the risk people in prison are exposed to, including prison staff.

Smallpox eradication was certified in 1980. Mpox has been endemic in Central and West African countries since it was first detected in 1958 . It is a zoonosis; cases are often found close to tropical rainforests where various animals carry the orthopoxvirus that causes the disease. In endemic countr...ies, most mpox infections in humans result from a primary animal-to-human transmission. Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. Transmission can also occur via the placenta from mother to fetus or through close contact during and after birth.

Soil-transmitted helminths are a group of intestinal worms that include Ascaris lumbricoides (giant roundworm), Trichuris trichiura (whipworm), and Ancylostoma spp. (A. duodenale, A. ceylanicum) and Necator americanus (hookworms). Despite the clear biological differences among the different species,... their transmission is characterized by the same sequence of events: (i) infected individuals excrete worm eggs through their stool in soil; (ii) under optimal conditions of moisture and temperature the excreted eggs develop into infectious stages; and (iii) finally, infection occurs through oral uptake (Ascaris, Ancylostoma and Trichuris) or skin penetration (Ancylostoma and Necator) of these infectious stages (embryonated eggs and third stage larvae) that reside in the soil and/or in the environment (referring to their common name).

Listening to what children in crisis have to say is not only a moral and ethical responsibility for donor and humanitarian actors, it is also a humanitarian obligation. Children’s right to participation is recognised in the United Nations Convention on the Rights of the
Child (UNCRC), which provi...des rights for children to express their views and ‘be heard and taken seriously’.

Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeholders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from ani...mals to humans.
Mpox is a viral illness caused by the monkeypox virus (MPXV). It can cause a painful rash, enlarged lymph nodes and fever. Most people fully recover, but some get very sick. The virus transmits from person to person through close, including sexual, contact. It also has animal reservoirs in east, central and west Africa, where spillovers from animals to humans can occasionally occur, sparking further outbreaks.
There are two different clades of the virus: clade I and clade II. Clade I outbreaks are deadlier than clade II outbreaks.
A major emergence of mpox linked to clade II began in 2017, and since 2022, has spread to all regions of the world. Between July 2022 and May 2023, the outbreak was declared a Public Health Emergency of International Concern. While that outbreak has largely subsided, cases and deaths continue to be reported today, illustrating that low-level transmission continues around the world.
Currently, there is also a major outbreak of clade I virus in the Democratic Republic of the Congo (DRC), where cases have been on the rise for decades. Since the beginning of the year, over 6500 cases and 345 deaths have been reported in the DRC. Almost half of these are among children under the age of 15 years.
The Strategic framework for enhancing prevention and control of mpox (2024–2027) provides a roadmap for health authorities, communities, and stakeholders worldwide to control mpox outbreaks in every context, advance mpox research and access to countermeasures, and to minimize zoonotic transmission.

Medicinal plants are globally valuable sources of herbal products, and they are disappearing at a high speed. This article reviews global trends, developments and prospects for the strategies and methodologies concerning the conservation and sustainable use of me...dicinal plant resources to provide a reliable reference for the conservation and sustainable use of medicinal plants. We emphasized that both conservation strategies (e.g. in situ and ex situ conservation and cultivation practices) and resource management (e.g. good agricultural practices and sustainable use solutions) should be adequately taken into account for the sustainable use of medicinal plant resources. We recommend that biotechnical approaches (e.g. tissue culture, micropropagation, synthetic seed technology, and molecular marker-based approaches) should be applied to improve yield and modify the potency of medicinal plants.
