State-of-the-art laboratory enhances Madagascar's polio response
The laboratory, which is fully accredited by World Health Organization (WHO), was handed over today to the national authorities. Hosted at the Institut Pasteur de Madagascar in the capital, Antananarivo, the laboratory reinforces the country's position as a regional pillar in rapid poliovirus detection and outbreak response.
'This commissioning symbolizes our collective commitment. It brings us closer to a future where no child in Madagascar—or anywhere—is at risk of polio,' said Dr Nely Alphonse José, head of plague, emerging and neglected tropical disease control department at the Ministry of Public Health.
Established in 2023, the laboratory has significantly enhanced Madagascar's ability to rapidly detect poliovirus through both acute flaccid paralysis and environmental surveillance. Between 2022 and 2024, the laboratory detected more than 40 cases of circulating variant poliovirus type 1, enabling immediate and targeted immunization responses. The efforts played a key role in halting an outbreak of circulating variant poliovirus type 1. In May 2025, Madagascar marked two full years without any new detections of the virus, which meant the outbreak was declared closed after a thorough assessment.
'This laboratory is not only a national asset—it's a regional resource,' said Dr Laurent Musango, WHO Representative in Madagascar. 'With strengthened capacity and cutting-edge technology, Madagascar is now even better positioned to lead the charge against poliovirus transmission in Eastern and Southern Africa.'
The handing over of the laboratory to the government marks a major step towards sustainable, country-led polio surveillance and self-sufficiency in managing future outbreaks and ensures strong measures are in place to sustain the country's polio-free status and contribute to the global goal of ending polio once and for all.
Thanks to ongoing collaboration between national health authorities, WHO, and with support from the Gates Foundation, the laboratory has also joined pilot projects to deploy innovative tools such as direct detection through Nanopore sequencing – a new technology that boosts the speed and accuracy of viral identification, eliminating previous delays when samples had to be shipped abroad for genomic sequencing.
WHO and its partners provided technical support, training, IT upgrades and environmental site optimization to strengthen the laboratory's operations—reinforcing national efforts to meet the objectives of the Global Polio Eradication Initiative.
Accredited for viral isolation, intratypic differentiation and environmental surveillance, the laboratory is now a cornerstone in Madagascar's integrated disease surveillance system. It ensures timely data to guide vaccination campaigns and outbreak responses across the country.

African Development Bank Project Enhances Water Access in Malawi Town
In the green hills of Rumphi, northern Malawi, the hum of progress can be heard at the newly established Rumphi Technical College. With its modern buildings, new equipment, and a sense of optimism, the college has quickly become a symbol of opportunity. In just four years, enrollment has grown from a small group of students to a thriving community of 534 young men and women, supported by 45 staff members. These students are full of ambition, hoping that their technical skills will pave the way for a brighter future. But behind the progress lies a daily challenge that affects everyone on campus: the lack of safe and reliable water. 'Sometimes, we're left with no choice but to send students to fetch water from unprotected sources including a salty borehole left by the contractor,' the college's principal Akuzike Nkhoma explained, a concerned expression crossing his face. 'It's neither safe nor sustainable.' Students share similar worries. They speak of long walks in the early morning to distant water points—time that could be spent in class. Just a few months ago, 100 students were taken to Rumphi District Hospital after a cholera scare on campus. The taps had run dry, and students had turned to unprotected sources, putting their health at serious risk. The water challenge at the college reflects a broader issue impacting the entire Rumphi community as revealed by a series of community engagements the Board has been conducting to prepare people for the upcoming project implementation. For many households, especially those in higher-altitude areas, access to water is unreliable, limited by the capacity of a small 200,000-liter tank that has long outgrown its ability to serve the town's needs. Francis Munthali, Chief Executive Officer for Northern Region Water Board (NRWB) acknowledges the strain Rumphi's growth has placed on the aging water system, 'Back then, this tank was enough because there weren't as many people as possible. But now, with more households, schools, and the town expanding, it simply can't meet the demand.' 'For example, if we are to sustain supply to the college, it means we have to ration in town where there is the main hospital and several facilities needing water. It's becoming clear that we're facing a real crisis,' highlights Munthali. The water supply infrastructure, managed by the NRWB, has reached its limits. The Rumphi Water Supply Scheme was last upgraded in 2003, designed to meet the demands of 2010, estimated at 1.5 million litres per day. Today, however, demand has surged to over 10 million litres per day, a more than tenfold increase. Despite this, no major rehabilitation work has been done since 2004, and the aging system can only serve 23% of the town's population. Water is available to residents for just a few hours. Not surprisingly, frustration echoes across Rumphi customer forums. One resident Dora Mkandawire highlights the toll persistent water challenges are exerting on women. 'We are the most heavily impacted because our society is programmed that it is us women who go to fetch water. These persistent interruptions are stealing our valuable time and affecting our productivity,' laments Mkandawire The water system is also concentrated in the town, leaving major trading centers reliant on unprotected traditional water sources, such as wells. Additionally, the district lacks a functioning sewer system. This limited access hampers not only households but also the broader economic potential of the area. In key trading centers along the national M1 road, such as Phwezi, Bwengu, and Enukweni, the situation is even bleaker. These communities rely on unprotected sources, whereas Bolero, home to Senior Chief Chikulamayembe, has a basic community-led gravity-fed water system that struggles to keep pace with local demand. Chief Chikulamayembe notes: 'Our people need more. Growth centres like ours should have reliable water sources to foster prosperity and health.' To address these challenges and pave the way for sustainable development, the Northern Region Water Board with financing from the African Development Bank and Malawi Government is implementing the Rumphi Water and Sanitation Services Project. The goal? To turn frustration into relief and ensure no community is left thirsty. The project which is expected to increase access to sustainable and climate resilient potable water supply and safely managed sanitation services at Rumphi Town and surrounding areas will benefit over 158 000 people of which 51 percent are expected to be female. The project will span almost the width and breadth of Rumphi - extending to some parts of Northern Mzimba. The project is also leaving no stone unturned and no-one behind as it prioritizes all key components including restoration of forest landscapes and ecosystem-based adaptation initiatives for sustainable water supply. 'Under this project, we are upgrading both water and sanitation facilities including planting and nurturing 700 000 trees as part of catchment management. For the first time, Rumphi town will have a proper sewer system to cater for residents apart from improved supply,' explained Catherine Mwafulirwa, Director of Infrastructure Development at Northern Region Water Board. 'We are also extending the water supply from the town to new areas such as Bolero, Phwezi, Bwengu and Enukweni. Presently, consultants are on the ground to prepare detailed designs and tendering assistance for both water supply and sanitation works. We expect to recruit contractor for the works before year end.' In this planting season, the NRWB has planted 264 000 trees according to Mwafulirwa which among other things led to the creation of hundreds of short-term jobs for the local communities in the raising of the nurseries for the tree seedlings as well as the planting exercise. 'Rumphi is growing, but without water and improved sanitation, development stalls," District Commissioner for Rumphi Emmanuel Bulukutu laments. 'This project is critical as it will not only support the thriving Technical College but also improve the quality of life for all residents, fostering a healthier, more prosperous community. 'We will therefore diligently work with the NRWB and all stakeholders to ensure that this project is successfully implemented within the stated period,' adds Bulukutu. Once completed, the project will complete the water supply puzzle of the M1 road stretch between Mzuzu and Rumphi. It means all people lying along the 83 kilometre Mzuzu-Ekwendeni-Enukweni-Bwengu-Phwezi stretch will have access to safely managed drinking water. 'With reliable water infrastructure and sanitation improvements, Rumphi would be poised to unlock its potential as a vibrant hub of human capital and economic activity in northern Malawi. This change would give students the chance to focus solely on their studies, ensure that households no longer struggle for basic resources, and create an environment where both people and businesses can thrive. For the people of Rumphi, this project isn't merely about water; it's about hope, dignity, and a future they can depend on,' emphasized the District Commissioner The African Development Bank Group is providing a $32.2 million grant with the Malawi Government contributing $3.67 million for the project to be implemented over a period of 4 years from December 2023 to December 2027.

World Health Organization (WHO) recommends injectable lenacapavir for Human Immunodeficiency Virus (HIV) prevention
The World Health Organization (WHO) released today new guidelines recommending the use of injectable lenacapavir (LEN) twice a year as an additional pre-exposure prophylaxis (PrEP) option for HIV prevention, in a landmark policy action that could help reshape the global HIV response. The guidelines are being issued at the 13th International AIDS Society Conference (IAS 2025) on HIV Science, in Kigali, Rwanda. LEN, the first twice-yearly injectable PrEP product, offers a highly effective, long-acting alternative to daily oral pills and other shorter-acting options. With just two doses per year, LEN is a transformative step forward in protecting people at risk of HIV – particularly those who face challenges with daily adherence, stigma, or access to health care. 'While an HIV vaccine remains elusive, lenacapavir is the next best thing: a long-acting antiretroviral shown in trials to prevent almost all HIV infections among those at risk," said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. 'The launch of WHO's new guidelines, alongside the FDA's recent approval, marks a critical step forward in expanding access to this powerful tool. WHO is committed to working with countries and partners to ensure this innovation reaches communities as quickly and safely as possible.' The new guidelines come at a critical moment as HIV prevention efforts stagnate with 1.3 million new HIV infections occurring in 2024 – with disproportionate impact among key and priority populations, including sex workers, men who have sex with men, transgender people, people who inject drugs, people in prisons, and children and adolescents. WHO's recommendation on LEN signals a decisive move to expand and diversify HIV prevention, giving people more options to take control over their health with choices that fit their lives. Simplified testing: a major barrier removed As part of these guidelines, WHO has recommended a public health approach to HIV testing using HIV rapid tests to support delivery of long-acting injectable PrEP, including LEN and cabotegravir (CAB-LA). The simplified testing recommendation removes a major access barrier by eliminating complex, costly procedures and enabling community-based delivery of long-acting PrEP through pharmacies, clinics, and tele-health. Next steps: call for implementation LEN joins other WHO-recommended PrEP options, including daily oral PrEP, injectable cabotegravir and the dapivirine vaginal ring, as part of a growing arsenal of tools to end the HIV epidemic. While access to LEN outside clinical trials remains limited at the moment, WHO urges governments, donors and global health partners to begin rolling out LEN immediately within national combination HIV prevention programmes – while collecting essential data on uptake, adherence and real-world impact. Additional WHO recommendations at IAS 2025 For the first time, WHO's treatment guidelines include a clear recommendation for the use of long-acting injectable cabotegravir and rilpivirine (CAB/RPV) as an alternative switching option for antiretroviral therapy (ART) for adults and adolescents who have achieved full viral suppression on oral ART and do not have active hepatitis B infection. This approach is designed to support people living with HIV facing adherence challenges to oral regimens. Updated guidelines on service delivery integration include recommendations to integrate HIV services with noncommunicable diseases (NCDs) such as hypertension and diabetes, as well as mental health care for depression, anxiety and alcohol use disorders into HIV services, alongside interventions to support ART adherence. Additionally, new guidelines on management of asymptomatic STIs recommend screening of gonorrhoea and/or chlamydia in key and priority populations. For people living with HIV who have mpox and are either ART naive or have experienced prolonged ART interruption, rapid initiation of ART is strongly recommended. Additionally, early HIV testing is advised for individuals presenting with suspected or confirmed mpox infection. WHO's standard operating procedures further emphasize HIV and syphilis testing for all individuals with suspected or confirmed mpox. In response to the broader challenges facing HIV programmes, WHO has also issued new operational guidance on sustaining priority HIV services in a changing funding landscape. The guidance aims to provide a stepwise framework to help countries prioritize services, assess risks, monitor disruptions, and adapt systems to protect health outcomes and preserve progress. 'We have the tools and the knowledge to end AIDS as a public health problem,' said Dr Meg Doherty, Director of WHO's Department of Global HIV, Hepatitis and STI Programmes and incoming Director of Science, Research, Evidence and Quality for Health. 'What we need now is bold implementation of these recommendations, grounded in equity and powered by communities.' HIV remains a major global public health issue. By the end of 2024, an estimated 40.8 million people were living with HIV with an estimated 65% in the WHO African Region. Approximately 630 000 people died from HIV-related causes globally, and an estimated 1.3 million people acquired HIV, including 120 000 children. Access to ART continues to expand, with 31.6 million people receiving treatment in 2024, up from 30.3 million in 2023. At a time of reduced funding for HIV and health, WHO's new and updated guidelines offer practical, evidence-based strategies to sustain momentum. By expanding prevention and treatment options, simplifying service delivery and promoting integration with broader health services, they support more efficient, equitable, and resilient HIV responses. Now is the moment for bold implementation to ensure these gains translate into real-world impact. Distributed by APO Group on behalf of World Health Organization (WHO).

UAE leads life-saving drive to tackle malnutrition in Yemen's Socotra
The UAE has joined forces with the World Health Organisation to lead a campaign to reduce the number of deaths caused by malnutrition on the Yemeni island of Socotra. Field teams from the UAE and the WHO have carried out assessments in the first phase of a drive aimed at bolstering health systems and improving patient care. Health workers have completed the first of four visits over the course of a year, as part of a mission to reduce the malnutrition death rate by up to 20 per cent within the next two to five years. The initiative is being carried out with the support of the Yemen's Ministry of Public Health and Population, state news agency Wam reported on Monday. The baseline assessment covered 38 villages across 29 subdistricts of Socotra, which has an estimated population of 60,000. Data was collected from 4,214 households, with field teams interviewing more than 900 care providers and taking anthropometric measurements from children and mothers. Such measurements are typically used to assess the height and weight of infants and adults. That data is an important indicator of nutrition and the risk of disease. The findings will be used to compile a report that will detail the maternal and child health and nutrition status of the community. It will also examine the readiness of healthcare sites to respond to emergency situations and meet the needs of patients. Future stages of the initiative will include the distribution of medical goods and other supplies, work by technical experts and service providers, and the launch of training programmes and community awareness campaigns. Remote island of global significance Socotra is part of one of the most isolated islands in the world. It is about 340km south-west of Yemen. While remote and small, it is known for its centuries-old, umbrella-shaped dragon blood trees and has been described as the Galapagos of the Indian Ocean because of its biodiversity. The Socotra Archipelago – made up of six islands, including its largest, Socotra – received Unesco World Heritage Site status in 2008 in recognition of its biodiversity and high number of endemic species. Socotra has endured a number of challenges in recent years, including two cyclones in 2015. The UAE provided $110 million in humanitarian aid to the people of Socotra from 2015 to 2021, offering assistance to its communities and helping to lay foundations for the future. The aid was delivered by organisations including the Emirates Red Crescent, the Abu Dhabi Fund for Development, the Khalifa bin Zayed Al Nahyan Foundation, the Sheikh Sultan bin Khalifa Al Nahyan Humanitarian and Scientific Foundation, and the Abu Dhabi Waste Management Centre. Key investment restored Socotra's airport and paid for the construction of two solar power stations, the establishment of four power plants and the installation of power generators in remote villages.
