Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim...ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

The meningitis road map has been designated as a flagship global strategy of the WHO’s Thirteenth General Programme of Work, 2019–2023 and is an essential component in achieving universal health coverage.
The road map will reinforce and combine with wider initiatives, such as those aimed at s...trengthening primary health care and health systems, increasing immunization coverage, improving global health security, fighting antimicrobial resistance and advocating for the rights of persons with disabilities. It will complement other global control strategies, such as those addressing sepsis, pneumonia, tuberculosis and HIV. Implementation will be a challenge for all countries across the world, but especially in resource-poor settings where the burden of meningitis is greatest. The targets for the visionary and strategic goals will be adapted to regional and local contexts.

People affected by impairments and disabilities associated with TB are even more likely to belong to marginalized segments of society and are more likely to have their human rights unprotected. The challenges faced by people affected by TB include the consequences of impairment and disability associ...ated with the disease, its treatment as well as with the stigma and discrimination applied to people affected by TB. There is now compelling evidence that the disease and its treatment affect quality of life and life expectancy even after successful treatment.
The WHO Global Tuberculosis Programme has produced the first policy brief on TB-associated disability, building on the increasing evidence in recent years on the unaddressed needs of people with TB who experience impairment and disability while on TB treatment and after completing TB treatment.

Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a...nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.

Ethiopia has been repeatedly affected by conflict, flooding, drought, and disease outbreaks in the past years. As of January 2024, the country is actively responding to the longest recorded cholera outbreak which started in August 2022, recurrent measles outbreaks which started in August 2021, and t...he highest number of malaria cases reported since 2017. The El Niño phenomenon is expected to cause further havoc up to July 2024, by causing drought in some parts of the country, and flooding in others. Food insecurity due to lost harvest and livestock is aggravating already high malnutrition rates, negatively impacting morbidity and mortality.
The Health Cluster is closely collaborating with the Ministry of Health (MOH) to prepare for, prevent, and respond to public health emergencies by mobilizing resources to enable health partners to provide life-saving health services to vulnerable populations.
In an environment with ever-increasing needs and decreased funding, the below priorities for 2024 and 2025 have been identified: 1 Strengthen advocacy for longer-term, development funding to address root causes of recurrent disease outbreaks, including through the Humanitarian-Development-Peace Nexus 2 Advocate for increased access to quality health services, with a strong focus on:
sexual and reproductive health services (including for survivors of sexual and gender-based violence)
inclusion of people with disabilities, older people, and people living with HIV
remote populations through inclusion of Mobile Health Teams (MHT) as part of the health system 3 Standardize health services provided by Health Cluster partners through the implementation of Essential Health Care packages, aligned with existing MOH guidance, aimed at ensuring quality service delivery for affected populations, especially at community level 4 Strengthen quality of, and access to data for needs analysis and informed decision-making 5 Strengthen subnational coordination, with increased focus on zones and local health partners

Birth defect has been an emerging major cause of child mortality in the region. Scarcity of the birth defects information hampers policy decisions and control measures at national level. In order to create evidence for action for birth defects prevention in the region, WHO-SEARO in collaboration wit...h CDC, USA has developed and launched a regional electronic database on birth defects. This surveillance database allows data collection on newborn health, birth defects and stillbirths cases and provides real time information at hospitals and national level.
Training of the hospital health staffs and data managers in the birth defects surveillance network; at regional, national and at hospital levels is recognized as essential for expansion of this database and to assure quality of data. A two days training module for hospital based birth defects surveillance was developed using a guide for operation and facilitator guide.

There is increasing interest in understanding the role of air pollution as one of the greatest threats to human health worldwide. Nine of 10 individuals breathe air with polluted compounds that have a great impact on lung tissue. The nature of the relationship is complex, and new or updated data are... constantly being reported in the literature. The goal of our review was to summarize the most important air pollutants and their impact on the main respiratory diseases (chronic obstructive pulmonary disease, asthma, lung cancer, idiopathic pulmonary fibrosis, respiratory infections, bronchiectasis, tuberculosis) to reduce both short- and the long-term exposure consequences. We considered the most important air pollutants, including sulfur dioxide, nitrogen dioxide, carbon monoxide, volatile organic compounds, ozone, particulate matter and biomass smoke, and observed their impact on pulmonary pathologies. We focused on respiratory pathologies, because air pollution potentiates the increase in respiratory diseases, and the evidence that air pollutants have a detrimental effect is growing. It is imperative to constantly improve policy initiatives on air quality in both high- and low-income countries.

Leishmaniasis is a climate-sensitive disease. Changes in temperature, rainfall, and humidity can have strong impacts on
the sandfly vector, altering their distribution and influencing their survival and population sizes. Increased temperatures shorten vector development time, reduce Leishmania para...site incubation time, and increase vector biting rates, allowing transmission
in areas not previously endemic for the disease. Poor and
marginalized communities will be hit disproportionately harder by
the effects of climate change, and droughts, famines, and floods
can also lead to displacement and migration of immunologically
naive people to areas where leishmaniasis is endemic, posing a
threat of leishmaniasis outbreaks.
