Schistosomiasis is an infectious disease caused by helminth parasites of the genus Schistosoma. Worldwide, an estimated 250 million people are infected with these parasites with the majority of cases occurring in sub-Saharan Africa. Within Asia, three species of Schistosoma cause disease. Schistosom...a japonicum is the most prevalent, followed by S. mekongi and S. malayensis. All three species are zoonotic, which causes concern for their control, as successful elimination not only requires management of the human definitive host, but also the animal reservoir hosts. With regard to Asian schistosomiasis, most of the published research has focused on S. japonicum with comparatively little attention paid to S. mekongi and even less focus on S. malayensis. In this review, we examine the three Asian schistosomes and their current status in their endemic countries: Cambodia, Lao People’s Democratic Republic, Myanmar, and Thailand (S. mekongi); Malaysia (S. malayensis); and Indonesia, People’s Republic of China, and the Philippines (S. japonicum). Prospects for control that could potentially lead to elimination are highlighted as these can inform researchers and disease control managers in other schistosomiasis-endemic areas, particularly in Africa and the Americas.

Foodborne trematode infections cause 2 million life years lost to disability and death worldwide every year.
People become infected by eating raw fish, crustaceans or vegetables that harbour the parasite larvae.
Foodborne trematodiases are most prevalent in East Asia and South America.
Foodborne ...trematode infections result in severe liver and lung disease.
Safe and efficacious medicines are available to prevent and treat foodborne trematodiases.
Prevention and management of food-borne trematodes requires cross-sectoral collaboration on the human-animal and ecosystems interface.

As of 14 December 2021, a total of 19 laboratory-confirmed human rabies cases has been reported in South Africa for 2021. The cases are from Eastern Cape, KwaZuluNatal and Limpopo provinces. In addition, four probable rabies cases were reported from KwaZulu-Natal and the Eastern Cape provinces. A pr...obable case of rabies is defined as a person who has had a history of contact with a suspected or confirmed rabid animal and has developed an acute encephalitis with hyperactivity and paralytic signs and symptoms that progressed and resulted in death, usually by cardiac or respiratory failure, typically within ten days.

The previous report of the WHO Expert Committee on this disease
followed a meeting in 1995. Intensive, coordinated efforts against HAT during
the intervening 18 years have resulted in a decrease in incidence to a point at
which elimination is considered feasible. This report provides informati...on about
new diagnostic approaches, new therapeutic regimens and better understanding
of the distribution of the disease with high-quality mapping. The roles of human
and animal reservoirs and the tsetse fly vectors that transmit the parasites are
emphasized. The new information has formed the basis for an integrated strategy
with which it is hoped that elimination of HAT will be achieved. The report also
contains recommendations on the approaches that will lead to elimination of the
disease.

Zimbabwe has, over the years, grappled with the repercussions of the climate crisis, which have led to erratic rainfall patterns characterized by either severe floods or prolonged periods of drought. The nation has experienced a concerning trend of numerous regions reporting rainfall levels below th...e usual during what should be "normal" years. The upcoming El Niño event forecasted for 2023-2024, which is associated with drier-than-average rainfall, is poised to exacerbate this predicament. It is expected to intensify aridity, significantly impacting food and animal production across many areas, including those typically classified as "dry regions."

The World Health Organization (WHO) highlights the significant health risks associated with household air pollution, primarily resulting from the use of inefficient and polluting fuels and technologies for cooking, heating, and lighting. In 2020, approximately 2.1 billion people—about one-third of... the global population—relied on open fires or inefficient stoves fueled by kerosene, biomass (such as wood, animal dung, and crop waste), and coal. This exposure led to an estimated 3.2 million deaths, including over 237,000 deaths of children under the age of five. The pollutants emitted from these sources contribute to a range of health issues, including respiratory infections, heart disease, stroke, chronic obstructive pulmonary disease, and lung cancer. The WHO emphasizes the urgent need for transitioning to cleaner fuels and technologies to mitigate these health risks.

Neonatal tetanus (NT), a severe newborn illness from the toxigenic strains of Clostridium tetani, persists in middle- and low-income countries due to non-sterile childbirth practices. Unlike smallpox and polio, tetanus cannot be eradicated: Clostridium tetani spores exist in the environment, and ani...mal reservoirs. However, elimination as a public health issue is achievable through widespread tetanus vaccination, clean deliveries, and proper umbilical cord care. The goal of eliminating maternal and neonatal tetanus (MNT) as a public health problem is considered met when all municipalities in a country have an annual incidence rate of NT of less than 1 case per 1000 live births. The Region of the Americas achieved the maternal and neonatal tetanus elimination (MNTE) target in 2017 when elimination was validated in the Republic of Haiti. Yet maintaining this progress requires continued efforts. High vaccination coverage, booster doses in countries lacking them, hygienic practices, and strong maternal and child health services are key. The Pan American Health Organization’s (PAHO) integrated maternal and neonatal immunization platform further strengthens this fight against early childhood diseases.

A erradicação da varíola humana (mpox em inglês) foi certificada em 1980. A varíola símia (mpox em inglês) é endêmica nos países da África Central e Ocidental desde a sua primeira detecção, em 1958. Trata-se de uma zoonose cujos casos geralmente ocorrem perto de florestas tropicais, ond...e diversos animais são portadores do ortopoxvírus causador da doença. A maioria das infecções em seres humanos pelo vírus da varíola símia em países onde a doença é endêmica é resultado de transmissão primária de animais para humanos. A transmissão de pessoa a pessoa pode ocorrer por meio de contato próximo com secreções respiratórias ou lesões cutâneas de uma pessoa infectada ou com objetos recém-contaminados. A transmissão também pode ocorrer através da placenta da mãe para o feto ou por contato direto durante ou após o parto. Até 21 de maio de 2022, 12 países onde não há varíola símia endêmica, em 2 regiões da Organização Mundial da Saúde (OMS), haviam notificado 92 casos confirmados da doença. Até 26 de agosto de 2022, 96 países sem endemicidade, de todas as 6 regiões da OMS, haviam notificado 45.198 casos confirmados de varíola símia, incluindo 6 óbitos. No mesmo período, os países onde a doença é endêmica notificaram 350 casos confirmados e 6 óbitos. Na Região das Américas, 29 países e territórios notificaram 23.479 (48%) casos confirmados e 3 óbitos. Diversos estudos observacionais sobre as vacinas de primeira geração demonstraram que a eficácia da vacinação contra a varíola humana na prevenção da varíola símia é de aproximadamente 85%. Atualmente, as vacinas originais (de primeira geração) contra a varíola humana não estão mais disponíveis.

Integrating neglected tropical diseases into global health and development: fourth WHO report on neglected tropical diseases evaluates the changing global public health landscape; assesses progress towards the 2020 targets; and considers the possible core elements of a strategic vision to integratin...g neglected tropical diseases into the 2030 Agenda of the Sustainable Development Goals.
Advances have been made through expanded interventions delivered through five public health approaches: innovative and intensified disease management; preventive chemotherapy; vector ecology and management; veterinary public health services; and the provision of safe water, sanitation and hygiene. In 2015 alone nearly one billion people were treated for at least one disease and significant gains were achieved in relieving the symptoms and consequences of diseases for which effective tools are scarce; important reductions were achieved in the number of new cases of sleeping sickness, of visceral leishmaniasis in South-East Asia and also of Buruli ulcer.
The report also considers vector control strategies and discusses the importance of the draft WHO Global Vector Control Response 2017–2030. It argues that veterinary public health requires a multifaceted approach across the human–animal interface as well as a multisectoral programme of work to protect and improve the physical, mental and social well-being of humans, including veterinary, water, sanitation and hygiene.
Integration of activities and interventions into broader health systems is crucial, and despite challenges, has the potential to accelerate progress towards universal health coverage while advancing the 2030 Agenda.
In short, this report drives the message home that “no one must be left behind”.
