The sub-Saharan African region, carries 90% of the over 250 million cases of schistosomiasis occurring worldwide. In this region, after Nigeria, Tanzania is second country having the highest cases of schistosomiasis and approximately 51.5%0 of the Tanzanian population is either exposed or live in ar...eas with high risk of exposure. The country is endemic to both Schistosoma mansoni and Schistosoma haematobium, these infections are common in communities characterised with limited access to water, sanitation, hygienic practices and health services. Schistosoma mansoni infection is associated with hepatosplenic disease characterised with hepatomegaly, splenomegaly, progressive periportal fibrosis (PPF) which can lead to portal hypertension and its related sequelae, mainly ascites, liver surface irregularities, oesophageal varices and haematemesis. The main consequences of S. haematobium infection are haematuria, dysuria, nutritional deficiencies, urinary bladder lesions, hydronephrosis, urinary bladder squamous cell carcinoma and in children, growth retardation. Preventive chemotherapy using mass drug administration (MDA) of praziquantel targeting primary school aged children is the main strategy for controlling schistosomiasis in Tanzania.

These guidelines have been compiled for education ministries or other educational leaders (including development partners, non-governmental or private organizations working with schools or directly with caregivers) who want to adapt and adopt resources to support the marginalized caregivers of child...ren with disabilities.
The guidance presented in this document was developed by a team of international and national experts following a proof-of-concept pilot4 of the resources in two countries. The work was carried out between February 2021 and January 2022. The pilots demonstrated that principles and activities described in the resources could be carried out, in practical terms, in line with existing government programmes supporting the implementation of disability-inclusive education.

Anopheles stephensi, a highly competent vector of Plasmodium falciparum and P. vivax, is considered an efficient vector of urban malaria. Until 2011, the reported distribution of An. stephensi was confined to certain countries of South Asia and parts of the Arabian Peninsula. Since then, the vector ...has been collected in Djibouti (2012), Ethiopia (2016), Sudan (2016), Sri Lanka (2017), Somalia (2019), and most recently Nigeria (2020) and Yemen (2021). WHO considers the spread of An. stephensi to be a major potential threat to malaria control and elimination in Africa and southern Asia and has recently launched an initiative against the spread of this vector in Africa.

The domestic regulation of public health emergencies (PHEs) is inextricably linked to the regulation of other types of disaster. PHEs are usually governed at least partly by general disaster and emergency laws. Moreover, there is significant overlap in the legal mechanisms used to respond to PHEs an...d other types of disaster, including the declaration of a state of disaster or emergency and the use of emergency powers. Even where PHEs are regulated by separate instruments, those instruments must surmount many of the same policy and practical challenges as general disaster laws, such as finely balancing competing considerations (e.g. speedy response versus due process), facilitating the coordination of a multitude of actors, and protecting the most vulnerable within society. Finally, many contemporary developments in disaster risk management (DRM), such as a greater emphasis on risk reduction and preparedness, are just as pertinent to PHEs as to other types of disaster.

Sleeping sickness is controlled by case detection and treatment but this often only reaches less than 75% of the population. Vector control is capable of completely interrupting HAT transmission but is not used because of expense. We conducted a full scale field trial of a refined vector control tec...hnology. From preliminary trials we determined the number of insecticidal tiny targets required to control tsetse populations by more than 90%. We then carried out a full scale, 500 km2 field trial covering two HAT foci in Northern Uganda (overall target density 5.7/km2). In 12 months tsetse populations declined by more than 90%. A mathematical model suggested that a 72% reduction in tsetse population is required to stop transmission in those settings. The Ugandan census suggests population density in the HAT foci is approximately 500 per km2. The estimated cost for a single round of active case detection (excluding treatment), covering 80% of the population, is US$433,333 (WHO figures). One year of vector control organised within country, which can completely stop HAT transmission, would cost US$42,700. The case for adding this new method of vector control to case detection and treatment is strong. We outline how such a component could be organised.

Nearly 260 000 people died in parts of Somalia between October 2010 and April 2012, including
133 000 children under five during the famine and food crisis in Somalia making it the worst famine in history.
A study commissioned and funded by the Food and Agriculture Organization of the United Natio...n’s food security and nutrition analysis unit for Somalia stated that the famine early warning systems clearly identified the risk of famine in South Central Somalia in 2010–2011 but timely action to prevent the onset of famine was not taken. The result was large scale
mortality, morbidity and population displacement.

Wiping out Trachoma from Nepal – How Nepal eliminated trachoma as a public health problem
WHO - 2018
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.

Taeniasis and cysticercosis caused by the parasite T. solium affect vulnerable populations,
mainly in Latin America, sub-Saharan Africa and Asia, where pigs (the intermediate host) roam
free and poor sanitation allows pigs access to human faeces.
As of 12 December 2022, over 645 million people worldwide have been diagnosed with COVID-19, with over 6.6 million deaths (4).
The Omicron variant, which emerged in late November 2021, and its subvariants, are now the dominant circulating viruses, contributing to the ongoing surge in several countr...ies (4). Vaccination has substantially reduced case numbers and hospitalizations in many countries,but limitations in global access to vaccines mean that many populations, including those in low- and middle-income countries, remain vulnerable. Even in vaccinated individuals, uncertainties remain about duration of protection and efficacy, and the degree of crossprotection with new variants.
There remains a need for more effective treatment and management for those affected by COVID-19. The pandemic – and the
explosion of both research and misinformation – has highlighted the need for trustworthy, accessible and regularly updated living
guidelines to place emerging findings into context and provide clear recommendations for clinical practice

In the last decade, Timor-Leste has made remarkable progress in strengthening its health system and improving the health status of its population. This has resulted in an increased life expectancy, and the achievement of Millennium Development Goals such as a reduction in infant and under-five morta...lity, an improvement in maternal and child health outcomes, and an increase in immunization coverage. Further, the country has successfully eliminated infectious diseases such as polio, measles, and maternal and neonatal tetanus. There is full political commitment to reducing the incidence of tuberculosis (TB) by 80% and the number of deaths due to TB by 90% by 2030. The country has made great progress in the context of the pandemic, having established numerous quarantine facilities/isolation centres; trained health-care workers; streamlined the procurement and supply of medicines, consumables, personal protective equipment and other equipment; and strengthened the capacity in critical care across secondary and tertiary health care, to better respond to future pandemics and other disaster situations.

Medical care for people caught up in armed conflict and other insecure environments saves lives and alleviates suffering. It is one of the most immediate and high priority needs of an affected population and is often the first type of response activated and/or requested by authorities and affected c...ommunities. Medical teams working in armed conflict and other insecure environments
frequently face serious threats to their security and safety, challenges to patient access, and at times limited acceptance by affected communities in which they work and parties to the conflict. Such difficulties are likely to increase (6) and
thereby creating a critical need to establish contact and trust with all sides in conflicts and in other insecure environments to ensure operational continuity. This trust can best be achieved when all sides perceive the medical teams to be neutral, impartial, and independent, and specifically not aiding (or being perceived to aid) any one party to achieve a military, political or economic
advantage. For medical teams that are deploying increasingly closer to the frontlines, the implications of and consequences for both staff and patients of teams not being fully prepared, and/or not fully comprehending the context in which they work, can be severe. Medical response can easily be hindered or compromised by intentional or unintentional acts and the behaviour and
conduct of the teams themselves

Rabies is a fatal viral zoonosis and serious public health problem.1 All mammals are believed to be susceptible to the disease, and for the purposes of this document, use of the term animal refers to mammals. The disease is an acute, progressive encephalitis caused by viruses in the genus Lyssavirus....
2 Rabies virus is the most important lyssavirus globally. In the
United States, multiple rabies virus variants are maintained in wild mammalian reservoir populations such as raccoons, skunks, foxes, and bats. Although the United States has been declared free from transmission of canine rabies virus variants, there is always a risk of reintroduction of these variants.The rabies virus is usually transmitted from animal to animal through bites. The incubation period is
highly variable. In domestic animals, it is generally 3 to 12 weeks, but can range from several days to months, exceeding 6 months.8 Rabies is communicable during the period of salivary shedding of rabies virus. Experimental and historic evidence documents that dogs, cats, and ferrets shed the virus for a few days prior to the onset of clinical signs and during illness. Clinical signs of rabies are variable and include inappetance, dysphagia, cranial nerve deficits, abnormal behavior, ataxia, paralysis, altered vocalization, and seizures. Progression to death is rapid. There are currently no known effective rabies antiviral drugs.
