WHO regrets the United States’ notification of withdrawal from WHO – a decision that makes both the United States and the world less safe. The notification of withdrawal raises issues that will be considered by the WHO Executive Board at its regular meeting starting on 2 February and by the World Health Assembly at its annual meeting in May 2026.

The World Health Organization (WHO) Member States this week advanced their negotiations on the Pathogen Access and Benefit‑Sharing (PABS) system in a resumed session of the Intergovernmental Working Group (IGWG) on the WHO Pandemic Agreement. The PABS system is a core element of the agreement adopted by the World Health Assembly (WHA) in May 2025.

During the session held on 20–22 January 2026, Member States continued text‑based negotiations on outstanding issues in the draft annex and exchanged views aimed at narrowing differences and identifying areas of convergence.

“I am encouraged by the progress we have made in several areas, with signs of emerging consensus for some parts of the Pathogen Access and Benefit‑Sharing system,” said IGWG Bureau co‑chair Ambassador Tovar da Silva Nunes, of Brazil. “As we look ahead to the fifth session, the focus will be on the outstanding, complex issues. The resumed session has helped us gain a clearer picture of where we stand.”

Established by the WHA, the IGWG is tasked, as a priority, with drafting and negotiating the PABS system, which is intended to enable safe, transparent and accountable sharing of pathogens with pandemic potential and their genetic sequence information, alongside the fair and equitable sharing of benefits arising from their use, including vaccines, therapeutics and diagnostics.

The resumed session was held following a request by Member States to extend the fourth meeting of the IGWG, which convened in December 2025.

“Member States have engaged in constructive discussions this week," said IGWG Bureau co-chair Mr Matthew Harpur, of the United Kingdom. "As we make progress towards the May deadline, I am encouraged by their willingness to work together and bridge differences to deliver an effective Pathogen Access and Benefit‑Sharing system."

Further meetings of the IGWG are scheduled in the coming months as Member States continue their negotiations.

“A strong Pathogen Access and Benefit‑Sharing system will be a cornerstone of a safer and more equitable world,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “I thank countries for their commitment to multilateral solutions.”

The outcome of IGWG’s work will be submitted to the Seventy‑ninth World Health Assembly in May 2026 for its consideration.

 

As the EU initiative on Health Security reaches its conclusion, an online resource remains available for partners and stakeholders.

Access to treatment for leprosy is essential to global efforts to eliminate leprosy, says the World Health Organization (WHO) ahead of World Leprosy Day, to be observed on 25 January.

Leprosy is an infectious disease caused by a type of bacteria, Mycobacterium leprae, and is one of the oldest diseases known to humanity. The disease predominantly affects the skin and peripheral nerves. Left untreated, the disease may cause progressive and permanent disabilities and causes stigma and social isolation However, the disease can be cured with multidrug therapy (MDT).

Efforts to eliminate leprosy have been leading to reductions in the number of new cases in many areas; of the 188 countries, areas or territories that submitted data in 2024, 55 reported zero cases. But still 172 717 new cases were detected worldwide and reported to WHO in the same year.

Many partners, including pharmaceutical companies such as Novartis, have been strong supporters of efforts to eliminate leprosy. WHO has collaborated with Novartis since 2000 to provide MDT and clofazimine, free of cost, to all leprosy patients worldwide. This partnership remains one of the most sustained pharmaceutical donation programmes in global health.

Marking 25 years of partnership, WHO and Novartis have extended a Memorandum of Understanding (MoU) for an additional 5 years (2026−2030). The extension makes provision for continued supply of MDT and also includes funding for procurement and distribution of single dose rifampicin (SDR) for post-exposure prophylaxis (PEP).

“The unwavering commitment of partners like Novartis over the past quarter-century has been foundational to the progress made against leprosy,” said Dr Jeremy Farrar, WHO Assistant Director-General for Health Promotion, Disease Prevention and Care. “Their steadfast support in ensuring free access to treatment has helped transform millions of lives and moved us closer to a world free from this ancient disease. This enduring collaboration exemplifies the power of global solidarity in health – a reminder that, together, we can overcome even the oldest and most entrenched health challenges when science, equity, and partnership align.”

Availability of free MDT has made it possible to cure the disease, prevent disabilities, mitigate stigma, and has enabled affected individuals to continue working and leading normal lives. Additionally, clofazimine has ensured the treatment of lepra reactions, which are characterized by sudden, severe inflammatory episodes, leading to disabilities, if left untreated.

“Leprosy is one of the oldest infectious diseases known to humanity and combatting it has been part of our company’s history since discovering the first effective cure,” said Dr Lutz Hegemann, President of Global Health at Novartis. “Over the last 25 years, we have reached millions of patients together with WHO, and we are committed to going further to pursue our vision of a world free of leprosy.”

While significant progress has been made, sustaining and building on this momentum requires political commitment, community engagement and continued collaboration and partnership.

The theme for this year’s World Leprosy Day is “Leprosy is curable, the real challenge is stigma”.

This year also marks the 25th anniversary of Mr Yohei Sasakawa’s work as the WHO Goodwill Ambassador for Leprosy Elimination. He said, “One of the most stubborn challenges that I encounter on my travels is the social stigma attached to leprosy, which can be more problematic than the disease itself, and which can persist beyond the end of treatment. This is particularly true for people who have been left with residual disabilities as a result of leprosy. They may face various forms of discrimination, including forced divorce, lost educational opportunities and unfair dismissal. Even after being cured, they endure the unending pain of social exclusion.”

As leprosy is one of the target diseases under the broader umbrella of Neglected Tropical Diseases (NTDs), this work also supports the unified global effort towards a world free of NTDs. Learn more about the collective action and join our campaign on World NTD Day 2026 on 30 January.

 Notes for editors

The NTD Roadmap 2021-2030 aims at elimination of leprosy (interruption of transmission). The Global Leprosy Strategy 2021–2030 underpinning the Roadmap, shifts the paradigm beyond the achievement of ‘elimination of leprosy as a public health problem’ toward interruption of transmission and elimination of leprosy disease. Contact screening along with scale-up of preventive chemotherapy and mitigation of stigma and discrimination constitute key pillars of this strategy. Beyond working to ensure that every person affected by leprosy is detected early and treated promptly, WHO leads efforts to combat the discrimination that persons affected by leprosy too often face.

 

 

The European Centre for Disease Prevention and Control (ECDC) has published public health considerations regarding the use of doxycycline post-exposure prophylaxis, commonly known as doxy-PEP, for the prevention of bacterial sexually transmitted infections (STIs).

Three new European Union reference laboratories are now in place to improve Europe’s response to health threats linked to food- and waterborne diseases. They will help national public health laboratories to improve testing, data quality and preparedness across the EU for the next seven years.

In two new global reports released today, the World Health Organization is calling on governments to significantly strengthen taxes on sugary drinks and alcoholic beverages. The reports warn that weak tax systems are allowing harmful products to remain cheap while health systems face mounting financial pressure from preventable noncommunicable diseases and injuries.

Since April 2012, and as of 5 January 2025, a total of 2 647 MERS cases, including 959 deaths, have been reported by health authorities worldwide.

Samir Hadjiabduli, Chief Migration Health Officer at the International Organization for Migration (IOM) in Egypt, shared insights on strengthening health security in migration and mobility contexts during a regional workshop on health challenges linked to mass population displacements taking place on 16–18 December 2025.

Today, the conflict in Sudan reaches its 1000th day, with over 20 million people requiring health assistance and 21 million desperately needing food.

Nearly three years of continuous violence, severe access constraints, and reduced funding have turned Sudan into the worst humanitarian crisis globally. An estimated 33.7 million people will need humanitarian aid this year.

The health system has been severely damaged by ongoing fighting, increasingly deadly attacks on health care, mass displacement, lack of essential medical supplies, and shortages of health personnel and funding. Despite sustained efforts by WHO and partners to restore and revive health services across the country, more than one third of health facilities (37%) remain non-functional, depriving millions of people of essential and lifesaving health services.

Since the start of the conflict in April 2023, WHO has verified 201 attacks on health care, resulting in 1858 deaths and 490 injuries. These attacks, which violate international humanitarian law, undermine access to lifesaving care and put health care workers, patients and caregivers at grave risk.

“One thousand days of conflict in Sudan have driven the health system to the brink of collapse. Under the strain of disease, hunger and a lack of access to basic services, people face a devastating situation,” said WHO Representative in Sudan, Dr Shible Sahbani. “WHO is doing what we can, where we can, and we know we are saving lives and rebuilding the health system. Despite the challenges, we are also working on recovery of the health system.”

The level of displacement is unprecedented. An estimated 13.6 million people are currently displaced, making Sudan the largest displacement crisis in the world. Fueled by poor living conditions, overcrowding in displacement sites, disrupted health and water, sanitation and hygiene services, and a breakdown of routine immunization, disease outbreaks are spreading, compounding the crisis. WHO is currently supporting the response to outbreaks of cholera, dengue, malaria, and measles, with cholera being reported from all 18 states, dengue from 14 states, and malaria from 16 states. Access to preventive and curative care, including for the management of chronic conditions and severe malnutrition, remains limited.

WHO works with Sudan’s Federal and State Ministries of Health and partners to improve access to critical health services across Sudan and rehabilitate the health system. Since the start of the conflict in April 2023, WHO has delivered 3378 metric tons of medicines and medical supplies worth about US$ 40 million, including diagnostic supplies, treatments for malnutrition, and diseases such as cholera, malaria, dengue, and emergency surgery, to 48 health partners for lifesaving operations. About 24 million people have received cholera vaccinations, and WHO has supported the country to introduce and scale up malaria vaccines. Additionally, more than 3.3 million people have accessed health care at WHO-supported hospitals, primary health care facilities, and temporary mobile clinics. More than 112 400 children with severe acute malnutrition with medical complications have received treatment at functional stabilization centres, all of which receive lifesaving WHO nutrition supplies. State and National public health laboratories have been equipped and strengthened to confirm disease outbreaks and enable a rapid response.

“As the relentless conflict renders some areas inaccessible, particularly in the Darfur and Kordofan regions, the population’s health needs continue to increase,” Dr Sahbani said. “To meet these mounting needs and prevent the crisis from spiraling out of hand, WHO and humanitarian partners require safe and unimpeded access to all areas of Sudan, and increased financial resources.”

Ultimately, WHO calls parties to the conflict to urgently work towards a ceasefire and peace for the people of Sudan.

 

The second WHO Global Summit on Traditional Medicine, jointly organized with the Government of India, concluded today in New Delhi, marking a major milestone for global health as it drew over 16 000 online registrations and brought together 800 delegates from more than 100 countries, including ministers from over 20 nations. Combined with a strong line up of 160 speakers, the global traditional medicine community shared insights on how traditional medicine (TM) can strengthen health systems with more safe, evidence-based, and affordable care. 

The energy in Delhi was palpable as ministers, scientists, Indigenous leaders, and practitioners came together to advance the WHO Global Traditional Medicine Strategy 2025–2034. The Summit was not just about dialogue – it was about action. WHO unveiled the Traditional Medicine Global Library, a first-of-its-kind digital platform consolidating 1.6 million resources on TM, from scientific studies to Indigenous knowledge. With advanced features like Evidence Gap Maps and an AI-powered tool, TMGL GPT, the Library promises to transform access to trusted information and accelerate research worldwide. 

Innovation took centre stage with the launch of Health & Heritage Innovations (H2I), an initiative to nurture breakthrough ideas that bridge traditional practices with cutting-edge technologies such as AI, genomics, and digital health. From over 1000 submissions, 21 finalists were announced at the Summit and will enter a year-long acceleration programme to refine prototypes, receive scientific and regulatory guidance, and connect with policy-makers and investors. 

WHO also announced the Strategic and Technical Advisory Group on Traditional, Complementary and Integrative Medicine (STAG-TM), a new advisory body to guide the Global Strategy. Comprised of 19 independent experts, STAG-TM will shape research priorities, develop standards, and advise on integration into health systems. At its inaugural meeting during the Summit, the group set urgent priorities: evidence generation, preservation of traditional knowledge, digital innovation, and capacity building. 

Countries rallied behind the Delhi Declaration, with commitments from 26 Member States, signaling a new era for traditional medicine. This collective pledge focuses on integrating traditional medicine into primary health care, strengthening regulation and safety standards, investing in research, and building interoperable data systems to track outcomes. It’s a shift from recognition to results – ensuring traditional medicine is not a parallel system but a driver of universal health coverage. 

“Through the Delhi Commitment, countries have agreed not only on why traditional medicine matters – but on how to act,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “Traditional medicine can help to address many of the threats to health of our modern world: the growing burden of noncommunicable diseases; inequitable access to health services; and climate change. It can help to support care that is person-centred, culturally grounded, and holistic.” 

Looking ahead, WHO will work with Member States to turn these commitments into reality– scaling access to trusted knowledge, accelerating innovation, and embedding TM into health systems everywhere. The Global Traditional Medicine Strategy 2025–2034 charts a bold course toward a future where care is more inclusive, culturally grounded, and resilient.

The World Health Organization (WHO) has validated Brazil for the elimination of mother-to-child transmission (EMTCT) of HIV, making it the most populous country in the Americas to achieve this historic milestone. This accomplishment reflects Brazil’s long-standing commitment to universal and free access to health services through its Unified Health System (SUS), anchored in a strong primary health-care system and respect for human rights.

“Eliminating mother-to-child transmission of HIV is a major public health achievement for any country, especially for a country as large and complex as Brazil,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “Brazil has shown that with sustained political commitment and equitable access to quality health services, every country can ensure that every child is born free of HIV and every mother receives the care she deserves.”

The milestone was marked during a ceremony in Brasília, attended by President Luiz Inácio Lula da Silva, Brazil’s Minister of Health Alexandre Padilha, and the Director of the Pan American Health Organization (PAHO) Dr Jarbas Barbosa, along with representatives from UNAIDS.

Meeting validation criteria

Brazil met all the criteria for EMTCT validation, including reducing vertical transmission of HIV to below 2% and achieving over 95% coverage for prenatal care, routine HIV testing, and timely treatment for pregnant women living with HIV. In addition to meeting the targets of the validation, Brazil demonstrated the delivery of quality services for mothers and their infants, robust data and laboratory systems, and a strong commitment to human rights, gender equality and community engagement.

The country implemented a progressive, subnational approach by first certifying states and municipalities with over 100 000 inhabitants, adapting the PAHO/WHO validation methodology to its national context while maintaining coherence across the country.

The evaluation, supported by PAHO, was conducted by independent experts who reviewed data, documentation, and health facility operations. Findings were then assessed by WHO’s Global Validation Advisory Committee, which formally recommended Brazil’s validation for elimination.

“This achievement shows that eliminating vertical transmission of HIV is possible when pregnant women know their HIV status, receive timely treatment, and have access to maternal health services and safe delivery,” said Dr Jarbas Barbosa, Director of PAHO. “It is also the result of the tireless dedication of thousands of health professionals, community health workers, and civil society organizations. Every day, they sustain the continuity of care, identify obstacles, and work to overcome them, ensuring that even the most vulnerable populations can access essential health services."

Part of a broader initiative

Over the past decade (2015-2024), more than 50 000 pediatric HIV infections have been averted in the Region of the Americas as a result of the implementation of the initiative to eliminate mother-to-child transmission of HIV.

Brazil’s success is part of the broader EMTCT Plus Initiative, which seeks to eliminate mother-to-child transmission of HIV, syphilis, hepatitis B, and congenital Chagas, in collaboration with UNICEF and UNAIDS. It is embedded within PAHO’s Elimination Initiative, a regional effort to eliminate more than 30 communicable diseases and related conditions in the Americas by 2030.

"I am delighted that Brazil has just been certified by WHO/PAHO for eliminating vertical transmission – the first country of more than 100 million people to do so,” said Winnie Byanyima, UNAIDS Executive Director. “And they did it by doing what we know works –prioritizing universal health care, tackling the social determinants that drive the epidemic, protecting human rights, and even – when necessary – breaking monopolies to secure access to medicines."

Global context

Brazil is one of 19 countries and territories worldwide that have been validated by WHO for EMTCT. Twelve of these are in the Region of the Americas. In 2015, Cuba became the first country in the world to be validated for EMTCT of HIV and the elimination of congenital syphilis. Other countries in the Region include Anguilla, Antigua and Barbuda, Bermuda, Cayman Islands, Montserrat, and Saint Kitts and Nevis in 2017; Dominica in 2020; Belize in 2023; and Jamaica and Saint Vincent and the Grenadines in 2024.

Outside the Americas, countries validated for EMTCT of HIV include Armenia, Belarus, Malaysia, Maldives, Oman, Sri Lanka, and Thailand.

 

The European Commission has adopted an Implementing Regulation establishing a new EU reference laboratory (EURL) for public health for respiratory viruses. This marks a significant step in reinforcing the European Union’s capacity to respond to serious cross-border threats.

A study published today shows how public health laboratories can become more resilient against future respiratory infectious diseases. The findings call for sustained capacity, better coordination and EU-level support.
