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.

Le secteur de la santé a beaucoup évolué au cours des 20 dernières années. Les innovations technologiques ainsi que notre connaissance des maladies ont contribué à allonger l’espérance de vie au 20ème siècle. Cependant, l’un des plus grands défis

u fait des procédures cliniques les plus récentes ou des équipements de haute technologie dernier cri, mais plutôt d’améliorer la sécurité des soins dispensés dans des environnements complexes, sous pression et où la
rapidité d’action joue un grand rôle. Dans ce type d’environnements, les choses peuvent souvent mal tourner. Des événements indésirables surviennent. Des dommages non intentionnels, mais graves, affectent des patients dans le cadre de
la pratique clinique habituelle ou consécutivement à une décision clinique.

Epidemiology
Chagas disease (American trypanosomiasis) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted to humans by infected triatomine bugs, and less commonly by transfusion, organ transplant, from mother to infant, and in rare instances, by ingestion of contaminated food or
...
drink.1-4 The hematophagous triatomine vectors defecate during or immediately after feeding on a person. The parasite is present in large numbers in the feces of infected bugs, and enters the human body through the bite wound, or through the intact conjunctiva or other mucous membrane.
Vector-borne transmission occurs only in the Americas, where an estimated 8 to 10 million people have Chagas disease.5 Historically, transmission occurred largely in rural areas in Latin America, where houses built of mud brick are vulnerable to colonization by the triatomine vectors.4 In such areas, Chagas disease usually is acquired in childhood. In the last several decades, successful vector control programs have substantially decreased transmission rates in much of Latin America, and large-scale migration has brought infected individuals to cities both within and outside of Latin America.

The aim of this toolkit is to guide countries on how to best estimate their current burden of dengue by combining existing data from dengue surveillance systems with on-going research efforts to measure the community burden
of dengue.
Conflicts and disasters, including pandemics, affect women and men in all their diversity differently, and women and girls often suffer the most. Crisis-related hardships combine and compound pre-existing disadvantages, for example, they often cause women’s working conditions to worsen while incre

meworks in enabling governments and institutions to prevent, detect and manage health crises while protecting human rights and supporting coordinated action across sectors. The guidance highlights lessons learned from the COVID-19 pandemic and examines how national laws, policies and emergency powers were used in many countries. It also identifies common gaps in legal preparedness and proposes key elements that should be included in national legislation, such as clear roles and responsibilities, early warning systems, protection of vulnerable groups and cooperation with humanitarian actors. Overall, the document serves as a practical tool to help countries review and strengthen their legal and policy frameworks for managing public health emergencies.

Schistosomiasis is a public health problem in tropical and subtropical regions of Africa, Asia, the Caribbean and South America. It is one of the neglected tropical diseases (NTDs) - a group of diseases and conditions that affect particularly low-income populations, worldwide.

ched a new road map for 2021-2030 that aims to end the suffering from NTDs by 2030, in line with the Sustainable Development Goals. The road map specifically targets the elimination of schistosomiasis as a public health problem, globally.
This guideline provides evidence-based recommendations in the following areas: prevalence thresholds, target age groups and frequency of PC, establishment of WASH and snail control activities to support control and elimination of schistosomiasis, diagnostic tests for the assessment of schistosomiasis infection in animal reservoirs, in snail hosts, and in humans.

One of the major achievements in the year 2022 was the beginning of the journey towards validation of
the elimination of mother to child transmission of HIV, syphilis, and hepatitis B. This is the culmination of years
of commitment and determination by the political leadership, national and international partnerships to
reduce the associated indices to levels that qualify for elimination.

Onchocerciasis used to be an important public health problem in Africa, with over 37 million people infected and millions suffering from debilitating skin disease, terrible itching, impaired vision and
blindness. But the epidemiological situation has improved dramatically over the last two decades.

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.

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.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological

placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).
