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.

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.

Yaws is targeted for eradication by 2030, using a strategy based on mass drug administration (MDA) with azithromycin. New diagnostics are needed to aid eradication. Serology is currently the mainstay for yaws diagnosis; however, inaccuracies associated with current serological tests makes it difficu...lt to fully assess the need for and impact of eradication campaigns using these tools. Under the recommendation of the WHO Diagnostic Technical Advisory Group (DTAG) for Neglected Tropical Diseases(NTDs), a working group was assembled and tasked with agreeing on priority use cases for developing target product profiles (TPPs) for new diagnostics tools.

Schistosomiasis is widely recognized as a disease that is socially determined. An
understanding of the social and behavioural factors linked to disease transmission and
control should play a vital role in designing policies and strategies for schistosomiasis
prevention and control. To this must b...e added the awareness that schistosomiasis is
also a disease of poverty. It still survives in poverty-stricken, remote areas where there
is little or no safe water or sanitation, and health care is scarce or non-existent. For
a variety of complex reasons, many of which are addressed in this book, the disease
is particularly prevalent in sub-Saharan Africa, and persists in certain areas of rural
China. This concern for human behaviour in an environment of poverty echoes the
concerns of the new research priority for “diseases of poverty” identified by the
Special Programme for Research & Training in Tropical Diseases.

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.
Taenia saginata is a zoonotic tapeworm that is of economic importance in countries where cattle are kept. The parasite is transmitted from human tapeworm carriers (taeniosis) to bovines (cysticercosis) by excretion of eggs or proglottids containing eggs into the environment via the stool. Bovines ca...n then ingest the eggs through contaminated feed or water. After ingestion, the eggs hatch and release oncospheres in the small intestines, where the oncospheres penetrate the intestinal wall to reach the blood circulation. This distributes them throughout the body, but primarily to muscle tissue, where they develop into cysticerci. For humans to become infected with T. saginata, raw or undercooked bovine meat or offal containing infective cysts must be consumed. Bovine cysticercosis has been associated with various environmental factors related to water sources, such as animals having access to surface water, flooding of pastures and proximity to wastewater sources.

Leishmaniases are a group of diseases of zoonotic importance caused by over 20 species of protozoa of the genus Leishmania, in which domestic dogs are considered to be the main reservoir for the disease. However, the involvement of other vertebrates as reservoirs for these parasites has also been in...vestigated. Therefore, the objective of the present study was to carry out a systematic review with meta-analysis on occurrences of leishmaniasis in equids. The case reports described animals with cutaneous symptoms of leishmaniasis (papules, nodules, ulcers or crusts) that regressed spontaneously, located mainly on the head and limbs, from which three species of protozoa were identified in the lesions: Leishmania braziliensis, Leishmania infantum and Leishmania siamensis. In turn, the meta-analysis showed a combined prevalence of 25%, although with high heterogeneity among the studies, which was attributed to the use of different methods for diagnosing the disease. Leishmaniasis in equids is a benign disease but it should be included in the differential diagnosis of cutaneous diseases among these species. Seroepidemiological studies are important in investigating and monitoring suspected exposure of these hosts to the parasite, especially in endemic areas. However, there is also a need to standardize diagnostic methods.

Antimicrobial resistance (AMR) is a major public health challenge, which is recognized as high priority area by the Government of India. The increasing consumption of antibiotics is one of the key drivers of antimicrobial resistance seen in bugs of public health importance. Irrational prescription o...f broad-spectrum antibiotics, poor regulations around sale of antibiotics, self-medication, lack of education and awareness regarding responsible use of antibiotics have been identified as some of the key factors driving antimicrobial resistance in our country. The ‘National Health Policy’ (2017), addresses antimicrobial resistance as one of the key issues and prioritises development of guidelines regarding antibiotic use, limiting the over-the-counter use of antibiotics, restricting the use of antibiotics as growth promoters in livestock, and pharmaco-vigilance including prescription audit inclusive of antibiotic usage in the hospital and community.

A group of enzootic and zoonotic protozoan infections, the leishmaniases constitute among the most severely neglected tropical diseases (NTDs) and are found in all continents except Oceania. Representing the most common infectious diseases, NTDs comprise an open-ended list of some 20 parasitic, bact...erial, viral, protozoan and helminthic infections. Called “diseases of the poor,” because of their characteristic prevalence in poor populations regardless of a country's income status, they infect over one billion people in over 140 countries, with about 90% of the global burden in Africa. While NTDs do not contribute significantly to global deaths, they are debilitating and remain the most common infections among the poor worldwide, preventing them from escaping poverty by impacting livelihoods such as agriculture and livestock, and affecting cognitive, developmental and education outcomes.

The WHO estimates that 19 million children aged 15 years or younger are visually impaired. Of these, 1.4 million are irreversibly blind and need visual rehabilitation interventions for full psychological and personal development. The remainder have visual problems that could be prevented or treated.... Identifying children with visual problems early in life so that they can benefit from medical and optical interventions remains a key challenge for most child eye health programmes. Reports from various low-and middle-income countries indicate that the age of children undergoing operation for cataract is frequently too high to achieve maximum benefit.

To enhance health co-benefits across urban policies which tackle air pollution and climate change, WHO, in cooperation with various international, national, and local partners, implemented the Urban Health Initiative (UHI) pilot project in Accra, Ghana. The Initiative prompted the health sector to u...se its influential position to demonstrate to decision-makers and the public the full range of health, environmental and economic benefits that can be achieved from implementing local emission reduction and energy access policies and strategies. Policy tracking, although not always considered, is a fundamental component of this procedure. It assesses the planning, implementation and progress of a policy to refine or adjust policies with the final objective of increasing the likelihood of the policy being successful. This report is an outcome of the last component of the UHI model process, Policy tracking and monitoring outcomes. The report proposes a framework for tracking urban health policies, with a special focus on the impacts of air quality and energy access on human health and well-being in African countries, giving some examples from the pilot project in Accra. The report also provides resources to survey air quality in cities and other tools to assess public health and the environmental impacts of urban policies and monitor or track their effects.

In 2014, an estimated 40 million women of reproductive age were infected with Schistosoma haematobium, S. japonicum and/or S. mansoni. In both 2003 and 2006, the World Health Organization (WHO) recommended that all schistosome-infected pregnant and breastfeeding women be offered treatment, with praz...iquantel, either individually or during treatment campaigns. In 2006, WHO also stated the need for randomized controlled trials to assess the safety and efficacy of such treatment. Some countries have yet to follow the recommendation on treatment and many programme managers and pregnant women in other countries remain reluctant to follow the recommended approach.
