The conditionality of this recommendation is largely driven by the current higher unit cost of pyrethroid-PBO ITNs compared
to pyrethroid-only LLINs and therefore the uncertainty of their cost-effectiveness. Furthermore, as PBO is less wash-resistant
than pyrethroids, its bioavailability declines ...faster over the three-year estimated life of an ITN; therefore, the added impact of
pyrethroid-PBO ITNs over that of pyrethroid-only LLINs may decline over time. The evidence comes from two sites in
eastern Africa with pyrethroid resistance and not from other geographies where transmission levels and vector characteristics
may vary. PBO acts by inhibiting certain metabolic enzymes, primarily oxidases, and so are likely to provide greater protection
than pyrethroid-only LLINs where mosquitoes display mono-oxygenase-based insecticide resistance mechanisms.

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.

This project aimed to reduce the risk of vector-borne infection with Chagas disease by
controlling triatomine bugs, the vectors transmitting the parasite of Chagas disease, and
establishing an epidemiological surveillance system with community participation.
Yaws is a disfiguring non-venereal disease caused by infection with the spirochaete. Treponema pallidum subspecies pertenue which is closely related to the causative agent of syphilis and those of the other endemic treponematoses, bejel and pinta. The disease is endemic in certain areas of the World... Health Organization (WHO) African, South-East Asia and Western Pacific regions. Of the neglected tropical diseases identified for elimination and eradication, yaws is one of two diseases targeted for eradication. In 1949, the Second World Health Assembly adopted resolution WHA2.36, which addresses yaws, bejel and pinta as major public health problems that need attention.

During the year 2022, COVID-19 continued to be a significant challenge in Eritrea as in many other countries across the world. As COVID-19 devastated communities around the world, WHO worked with the MoH to strengthen the National and Sub-National health systems in order to meet community needs and ...mitigate the devastation during the pandemic and beyond.
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.

In 2005, the World Health Organization (WHO) recognized Chagas disease (CD; Trypanosoma cruzi infection) as a neglected tropical disease (NTD) [1] and included it into the global plan to combat NTDs [2]. The Target 3.3 of the United Nations Sustainable Development Goals (UN/SDG) aims at ending the e...pidemics of NTDs by 2030 [3]. Mother-to-child (congenital/connatal) transmission is currently the main mode of transmission of T. cruzi over blood transfusions and organ transplantations in vector-free areas within and outside Latin America (LA). Based on recent demonstrations that congenital transmission can be prevented [4–7], WHO has shifted its objective, in 2018, from control to elimination of congenital CD (cCD).

This sourcebook aims to detail why health needs to be part of urban and territorial planning and how to make this happen. It brings together two vital elements we need to build habitable cities on a habitable planet: 1) Processes to guide the development of human settlements – in this document ref...erred to as “urban and territorial planning (UTP)”; and 2) concern for human health, well-being and health equity at all levels – from local to global, and from human to planetary health.
This sourcebook identifies a comprehensive selection of existing resources and tools to support the incorporation of health into UTP, including advocacy frameworks, entry points and guidance, as well as tools and illustrative case studies. It does not provide prescriptions for specific scenarios – these should be determined by context, people and available resources.

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.

Chagas disease, also known as American trypanosomiasis, is a neglected tropical disease transmitted by triatomine insects, first identified in 1909. Chagas disease affects approximately 6–7 million peop...le globally and is highly prevalent in Latin America where most cases are reported. However, there is increasing evidence that Chagas disease is now an important public health issue outside the “classical” endemic countries due to population migration. Our understanding of Chagas disease, including its pathologies and factors relating to progression, remains to date limited, and is also challenged by lack of diagnosis and highly effective treatment. This systematic review aims to describe studies with Chagas patients receiving antiparasitic treatment. Databases were searched for relevant studies published after 1997, and the results of these searches were screened.

Notable progress has also been made on other key health indicators such as reducing maternal, infant and child deaths and malnutrition, increasing immunization coverage, eliminating infectious diseases such as polio and reducing the incidence of malaria, tuberculosis and diarrhoeal diseases.
But ...despite such substantial progress, the country now faces new and emerging new challenges such as the rising burden of noncommunicable diseases, increased risks associated with disasters, environmental threats and health emergencies during disease outbreaks including the COVID-19 pandemic that is a serious public health threat to Bangladesh. To establish a resilience system for future potential pandemics, the national capacity for emergency preparedness and early response to health emergencies needs to be bolstered considerably.

A key component of elimination is to reduce the number
of unmanaged trachomatous trichiasis cases to less than
1 per 1,000 population in affected areas. This will require
not only a large increase in the number of surgeries
performed, but also improvements in the quality of surgery
and in the e...fficiency of surgery provision programs. It also
will require that we make special efforts to reach out to
women and the most marginalized populations, who are
disproportionally affected by trichiasis (TT).

Countries, partners, and donors are committed to
the global elimination of blinding trachoma by 2020.
Achieving this public health milestone requires more
than funding; it requires health personnel with the
right mix of skills, and well supported and managed
health systems. Mass drug administra...tion (MDA)
with Zithromax®, the Pfizer, Inc. donated antibiotic,
is a key component of the SAFE strategy, endorsed
by the World Health Organization. There is growing
recognition that improving all aspects of MDA, from
planning to training, recording to reporting, and
receipt of drug to distribution (the supply chain), will
be necessary if MDA programmes are going to reduce
the community burden of Chlamydia trachomatis, and
eliminate trachoma as a cause of blindness by 2020.
