Trachoma causes more vision loss and blindness than any other infection in the world. This disease is caused by Chlamydia trachomatis bacteria. Other variants or strains of these bacteria can cause a sexually transmitted infection (chlamydia) and disease in lymph nodes.
This is photomicrograph ...of a conjunctival smear that revealed the presence of what are known as, intracytoplasmic inclusions Trachoma is easily spread through direct personal contact such as from fingers, through shared towels and clothes, and through flies that have been in contact with the eyes or nose of an infected person. When left untreated, repeated Chlamydia trachomatis infections in the eye can cause severe scarring on the inside of the eyelid. This can cause the eyelashes to scratch the cornea (trichiasis). In addition to causing pain, trichiasis permanently damages the cornea and can lead to irreversible blindness.
Chlamydia trachomatis infections spread in areas that lack access to safely managed drinking water and sanitation systems. Trachoma affects the most resource-limited communities in the world. Globally, almost 1.9 million people have vision loss because of trachoma, and it causes 1.4% of all blindness worldwide.1 In 2021, 136 million people lived in trachoma-endemic areas and were at risk of trachoma blindness.

Snakebite envenoming is a serious public health problem in Central America, where approximately 5,500 cases occur every year. Panama has the highest incidence and El Salvador the lowest. The majority, and most severe, cases are inflicted by the pit viper Bothrops asper (family Viperidae), locally kn...own as ‘terciopelo’, ‘barba amarilla’ or ‘equis’. About 1% of the bites are caused by coral snakes of the genus Micrurus (family Elapidae). Despite significant and successful efforts in Central America regarding snakebite envenomings in the areas of research, antivenom manufacture and quality control, training of health professionals in the diagnosis and clinical management of bites, and prevention of snakebites, much remains to be done in order to further reduce the impact of this medical condition. This essay presents seven challenges for improving the confrontation of snakebite envenoming in Central America. Overcoming these challenges demands a coordinated partnership of highly diverse stakeholders though inter-sectorial and inter-programmatic interventions.

Background: A recent report by the Institute for Health Metrics and Evaluation (IHME) highlights that mental health receives little attention despite being a major cause of disease burden. This paper extends previous assessments of development assistance for mental health (DAMH) in two significant w...ays; first by contrasting DAMH against that for other disease categories, and second by benchmarking allocated development assistance against the core disease burden metric (disability-adjusted life year) as estimated by the Global Burden of Disease Studies. Methods: In order to track DAH, IHME collates information from audited financial records, project level data, and budget information from the primary global health channels. The diverse set of data were standardised and put into a single inflation adjusted currency (2015 US dollars) and each dollar disbursed was assigned up to one health focus areas from 1990 through 2015. We tied these health financing estimates to disease burden estimates (DALYs) produced by the Global Burden of Disease 2015 Study to calculated a standardised measure across health focus areas—development assistance for health (in US Dollars) per DALY.

Asia remained the world’s most disaster-hit region from weather, climate and water-related hazards in 2023. Floods and storms caused the highest number of reported casualties and economic losses, whilst the impact of heatwaves became more severe, according to a new report from the World Meteorolog...ical Organization (WMO).
The State of the Climate in Asia 2023 report highlighted the accelerating rate of key climate change indicators such as surface temperature, glacier retreat and sea level rise, which will have major repercussions for societies, economies and ecosystems in the region.
In 2023, sea-surface temperatures in the north-west Pacific Ocean were the highest on record. Even the Arctic Ocean suffered a marine heatwave.
Asia is warming faster than the global average. The warming trend has nearly doubled since the 1961–1990 period.

n light of the potential risk posed by SARS-CoV-2 variants, in January 2021 WHO organized an ad hoc consultation to discuss the development of an R&D agenda in response to existing and emerging SARS-CoV-2 variants.
The key objectives were to identify the critical research questions related to var...iants and agree on a research approach to address them. Six breakout groups covered a range of specific issues related to COVID-19 variants: Epidemiology and mathematical modelling; evolutionary biology; animal models; assays and diagnostics; clinical management and therapeutics; and vaccines.

A global food crisis fuelled by conflict, climate shocks and the COVID-19 pandemic is growing because of the ripple effects of the war in Ukraine driving rising prices of food, fuel and fertilizer. Millions of people across the world are at risk of being driven into starvation unless action is taken... now to respond together and at scale. Due to the unprecedented overlap of crises, WFP’s annual operational requirements are at an all-time high of US$22.2 billion, with confirmed contributions so far at US$4.8 billion (22 percent). WFP is calling for coordinated action to address this crisis.

How to address the global crisis in antibiotic research and development.
The report includes a comprehensive summary and critical evaluation of recent initiatives to overcome the barriers to achieve sustainable access to antibiotics. As antibiotic resistance will continue to develop as long as we ...depend on these medicines to treat bacterial infections, a continuous supply of new effective antibiotics is needed. The report identifies five key challenges that must be solved in order to achieve sustainable access for all, and charts out options for governmental action in response to each of them.

Many children will not be ‘safe to learn at home’: As of April 2020, 91 percent of the world’s students have been affected by school closures due to COVID-19. While schools are often places where violence occurs, they also offer a comparatively protective and nurturing space for many children.... Especially for the most vulnerable learners -the poorest and most left behind- that rely on school not only for learning and development, but also for food, trusted and accurate information on important issues such as hygiene, and their overall physical and mental health.
