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.

Hepatitis B (HBV) infection is a major public health problem and cause of chronic liver disease.
The 2024 HBV guidelines provide updated evidence-informed recommendations on key priority topics. These include expanded and simplified treatment criteria for adults but now also for adolescents; expa...nded eligibility for antiviral prophylaxis for pregnant women to prevent mother-to-child transmission of HBV; improving HBV diagnostics through use of point-of-care HBV DNA viral load and reflex approaches to HBV DNA testing; who to test and how to test for HDV infection; and approaches to promote delivery of high-quality HBV services, including strategies to promote adherence to long-term antiviral therapy and retention in care.
The 2024 guidelines include 11 updated chapters with new recommendations and also update existing chapters without new recommendations, such as those on treatment monitoring and surveillance for liver cancer.

Since 2000, concerted efforts by national programmes, supported by public–private partnerships, nongovernmental organizations, donors and academia under the auspices and coordination of the World Health Organization (WHO), have produced important achievements in the control of human African trypan...osomiasis (HAT). As a consequence, the disease was targeted for elimination as a public health problem by 2020. The Sixty-sixth World Health Assembly endorsed this goal in resolution WHA66.12 on neglected tropical diseases, adopted in 2013.
National sleeping sickness control programmes (NSSCPs) are core to progressing control of the disease and in adapting to the different epidemiological situations. The involvement of different partners, as well as the support and trust of long-term donors, has been crucial for the achievements.

The new Global AIDS Strategy 2021--2026, End Inequalities, End AIDS, is a bold approach that uses an inequalities lens to close the gaps preventing progress to end AIDS
Intra-African migration remains a dominant trend in contemporary African migration. The Strategy frames the Organization’s new orientation with Africa at policy and strategic levels. It is consistent with the goals and objectives of the Global Compact for Safe, Orderly and Regular Migration (GCM) ...to which almost all African countries adhere, as well as the 2030 Agenda for sustainable development, the IOM strategic vision, and IOM Migration Governance Framework (MIGoF).

This practical guideline establishes definitions for “contact”, “contact person”, “contact tracing” and other associated concepts. It allows for improvement of contact tracing strategies and provides recommendations attempting to answer some, though not all, questions that arose during t...he 2019 coronavirus pandemic and other outbreaks. The use of this guideline begins once people have been diagnosed and the potential for transmission exists. It is not, however, intended to assist with case investigation. The guideline empowers health workers, governments, and public health officials with the tools to implement effective contact tracing strategies.

The purpose of this guidance is to assist WHO Member States, and other stakeholders, in the establishment and development of programmes of integrated surveillance of antimicrobial resistance in foodborne bacteria (i.e., bacteria commonly transmitted by food). In this guidance, “integrated surveill...ance of antimicrobial resistance in foodborne bacteria” is defined as the collection, validation, analyses and reporting of relevant microbiological and epidemiological data on antimicrobial resistance in foodborne bacteria from humans, animals, and food, and on relevant antimicrobial use in humans and animals. Integrated surveillance of antimicrobial resistance in foodborne bacteria therefore includes data from relevant food chain sectors (animals, food and humans) and includes data on both antimicrobial resistance and antimicrobial use. Integrated surveillance of antimicrobial resistance for foodborne bacteria expands on traditional public health surveillance to include multiple elements of the food chain, and to include antimicrobial use data, to better understand the sources of infection and transmission routes.

To test for ethnic discrimination in access to outpatient health care services, we carry out
an email-correspondence study in Germany. We approach 3,224 physician offices in the 79
largest cities in Germany with fictitious appointment requests and randomized patients’
characteristics. We find t...hat patients’ ethnicity, as signaled by distinct Turkish versus Ger-
man names, does not affect whether they receive an appointment or wait time. In contrast,
patients with private insurance are 31 percent more likely to receive an appointment. Hold-
ing a private insurance also increases the likelihood of receiving a response and reduces the
wait time. This suggests that physicians use leeway to prioritize privately insured patients
to enhance their earnings, but they do not discriminate persons of Turkish origin based
on taste. Still, their behavior creates means-based barriers for economically disadvantaged
groups.

Snakebite envenoming affects millions of people worldwide annually and is a significant source of mortality. Preventing and treating the problem is complex and requires collaboration among the fields of public health, medicine, ecology, and laboratory science. After being removed from the category A... neglected tropical disease (NTD) list in 2013, snakebite envenoming was reinstated in 2017 in response to antivenom shortages and advocacy from researchers and international NGOs. In 2019, the World Health Organization (WHO) set a target to halve the number of deaths and cases of snakebite envenoming by 2030.
