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.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...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).

Infections by the soil-transmitted helminths (STH), including Ascaris lumbricoides, Trichuris trichiura, Ancylostoma duodenale/Necator americanus (hookworms), and Strongyloides stercoralis, disproportionately affect children around the world. Because of their transmission associated with poor sanita...ry conditions and inadequate hygiene practices, higher burden of disease is seen in children from developing countries from sub-Saharan Africa, Southeast Asia, and Latin America. Approximately 267 million preschool-age children (PSAC) and 568 million school-age children (SAC) worldwide are at risk of STH infection as well as impaired child growth and cognitive development from A. lumbricoides, T. trichiura, and hookworm infections, and death due to severe S. stercoralis infection. Thus, their control is a global health priority.

Rabies is fatal, vaccine-preventable disease responsible for an estimated 59,000 human deaths each year. Most cases are transmitted by dogs, and most deaths occur in underserved populations in Africa and Asia. Approximately 40% of deaths occur in children.
In their 2015 declaration "Transforming our world: the 2030 Agenda for Sustainable Development", Member States pledged to end the epidemics of AIDS, tuberculosis, malaria and neglected tropical diseases by 2030, and to combat hepatitis and other communicable diseases. This report reviews progress an...d challenges in the global response to reduce the burden of these diseases in the context of the Millennium Development Goals, and looks ahead to identify the strategies and approaches that will be needed to accelerate progress during the new development era. The report was developed by WHO's Cluster for HIV/AIDS, TB, Malaria and Neglected Tropical Diseases in 2015.

Rabies is a neglected zoonotic disease with a global burden of approximately 59,000 human deaths a year. Once clinical symptoms appear, rabies is almost invariably fatal; however, with timely and appropriate post-exposure prophylaxis (PEP) consisting of wound washing, vaccine, and in some cases rabi...es immunoglobulin (RIG), the disease is almost entirely preventable. Access to PEP is limited in many countries, and when available, is often very expensive.

Each year, rabies causes approximately 59,000 deaths worldwide. Despite evidence that control of dog rabies through animal vaccination programs and elimination of stray dogs can reduce the incidence of human rabies, dog rabies remains common in many countries and exposure to rabid dogs is still the ...cause of over 90% of human exposures to rabies and of 99% of human rabies deaths worldwide. CDC experts in the Poxvirus and Rabies Branch conduct an annual assessment of individual countries’ rabies status worldwide which considers the presence of wildlife rabies, canine rabies variant (dog rabies), and non-rabies lyssaviruses.

Rabies is a zoonotic, vaccine-preventable viral disease that causes damage to the brain and spinal
cord in infected animals and humans. A zoonotic disease is a disease that can be transmitted
between animals and humans. Rabies is nearly 100% fatal once symptoms appear.
Rabies is an infectious viral disease that is almost always fatal once clinical symptoms appear.
In most cases, the disease is transmitted to humans by the bite of a rabid dog, but infection can also spread through scratches or via saliva.
Rabies kills one person every 9 minutes and children aged ...5–14 years are frequent victims.
Yet rabies is 100% vaccine preventable. Vaccinating dogs is the most cost-effective way to prevent rabies in people.
Education about dog behaviour, immediate care measures after a bite, responsible dog ownership and bite prevention are essential components of rabies elimination.
WHO and partners aim to achieve zero human rabies deaths by 2030.
The time to act is now.

Cervical cancer continues to be a significant public health problem and a major cause of premature mortality among women, disproportionately affecting the socioeconomically disadvantaged population in low- and middle-income countries (LMICs). In the absence of implementing the known evidence-based, ...cost-effective interventions, the number of deaths per year is projected to reach approximately 416 000 globally in 2035. It was estimated in 2020 that 32% of incident cervical cancer cases and 34% of cervical cancer deaths in the world occurred in the 11 Member States of the WHO South-East Asia (SEA) Region. In 2020, 190 874 new cases and 116 015 deaths were estimated due to cervical cancer, which is the third commonest cancer in the Region

Les conflits et les guerres ont des effets catastrophiques sur la santé et le bien-être des nations, et ils ont considérablement évolué au cours des dernières décennies. Avec la forte augmentation des crises humanitaires, y compris de la violence urbaine, de plus en plus de gens sont touchés... pendant des périodes plus longues par des interruptions des services élémentaires, devenues une triste réalité.
Les interventions sanitaires et les approches novatrices face aux défis que posent les
crises humanitaires peuvent sauver des vies et atténuer les conséquences des conflits
pour les civils.
Les équipes médicales qui interviennent lors de conflits armés et dans d’autres
environnements dangereux sont fréquemment confrontées à de graves menaces pour
leur sécurité et leur sûreté. Elles doivent surmonter ces difficultés pour avoir accès
aux patients, d’autant plus qu’elles se heurtent parfois à la réticence des populations
auprès desquelles elles interviennent et qui sont parties au conflit.
Une riposte médicale fondée sur des principes se compose d’interventions cliniques
et opérationnelles inspirées et respectueuses de normes fondamentales, qui mettent
l’accent sur la qualité, la sécurité et la protection dans l’intérêt des patients.

Children are at high risk of dog bites and contracting rabies. Forty percent of reported rabies cases worldwide are children under the age of fifteen. In our project areas, the proportion of children dying is often even higher. Rabies most often persists in poor communities and rural regions of deve...loping countries in Africa and Asia. If the risks are widely understood and appropriate dog bite treatment is well known – rabies is 100% preventable.

In March 2018, a family and their sick puppy travelled through heavy rains in Malawi to a rabies vaccination drive. The puppy had bitten the family’s 12-year-old son, Isaiah Mzonda several days before and tested positive for rabies during the vaccination drive. Without appropriate prevention and t...reatment, rabies is fatal. Therefore, the rabies bite was a potential death sentence for the family’s young son who had not received any post-exposure treatment.

Rabies is a vaccine-preventable, zoonotic, viral disease affecting the central nervous system. Once clinical symptoms appear, rabies is virtually 100% fatal. In up to 99% of cases, domestic dogs are responsible for rabies virus transmission to humans. Yet, rabies can affect both domestic and wild an...imals. It spreads to people and animals via saliva, usually through bites, scratches or direct contact with mucosa (e.g. eyes, mouth or open wounds). Children between the age of 5 and 14 years are frequent victims.

Clin Microbiol Infect 2010; 16: 225–231 Abstract In non-endemic countries, acute (invasive) schistosomiasis (AS) is typically seen in non-immune travellers, whereas chronic schistosomiasis is more frequently diagnosed in immigrants. Travellers with AS initially present with non-specific signs such... as fever, cough, headache, and urticaria. Life-threatening cardiac and neurological complications may occur. The positive diagnosis of AS relies on seroconversion, which appears together with hypereosinophilia approximately 3 weeks after the onset of symptoms. When prescribed during AS, praziquantel usually does not prevent the chronic phase of the disease and is associated with exacerbation of signs and symptoms in approximately 50% of cases. According to the published literature, corticosteroids may be recommended alone or in association with praziquantel. When associated with corticosteroids, pharmacokinetic interactions may impair the efficacy of praziquantel. We suggest that corticosteroids should be restricted to use in patients with systemic complications of AS, whereas praziquantel should be initiated only when ova are detected in either stools or urine, depending on the culprit species.

Chagas disease (American trypanosomiasis) is endemic in 21 countries of the Americas, where control is largely focused on elimination of the domestic insect vectors (Triatominae) coupled with measures to extend and improve the screening of blood donors in order to avoid tranfusional transmission. Th...rough national programmes and multinational initiatives coordinated by WHO-PAHO, much has been accomplished in these domains in terms of reducing transmission. Attention now turns to consolidating the successes in interrupting transmission, and improved treatment for those already infected and those who may become affected in the future. This article, based on technical discussions at the "Epidemiological and Sociological Determinants of Chagas Disease, Basic Information to Establish a Surveillance and Control Policy " meeting in Rio de Janeiro, is designed to open the debate on appropriate strategies for continuation of the successful initiatives against Chagas disease.

Soil-transmitted helminths (STH) affect 1.45 billion people worldwide, and high intensity infections are associated with anemia, undernutrition and impaired cognition, particularly among children. Mathematical models suggest it may be possible to interrupt the transmission of STH in a community by e...xpanding mass drug administration (MDA) from targeted high-risk groups (primarily school-aged children and women of child-bearing age) to all community members with high coverage. The DeWorm3 Project will test the feasibility of this approach to interrupting the transmission of STH using a series of cluster randomized trials in Benin, India and Malawi. Each study area (population 80,000) will be divided into 40 clusters and randomized to community-wide or standard-of-care targeted MDA for three years. Two years following the final round of MDA, prevalence of STH will be compared between arms and transmission interruption assessed in each cluster. The DeWorm3 trials will provide stakeholders with information regarding the potential to switch from STH control to a more ambitious and sustainable strategy.
