Recency assays use one or more biomarkers to identify whether HIV infection in a person is recent (usually within a year or less) or longstanding. Recency assays have been used to estimate incidence in representative cross-sectional surveys and in epidemiological studies to better understand the pat...terns and distributions of new and longstanding HIV infections.
This technical guidance outlines best practices regarding the appropriate use of HIV recency assays for surveillance purposes and updates 2011 technical guidance from the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) on the use of HIV recency assays.

The indicators and questions in this document are designed for use by national AIDS programmes and partners to assess the state of a country’s HIV and AIDS response, and to measure progress towards achieving national HIV targets. Countries are encouraged to integrate these indicators and questions... into their ongoing monitoring efforts and to report comprehensive national data through the Global AIDS Monitoring (GAM) process. In this way they will contribute to improving understanding of the global response to the HIV epidemic, including progress that has been made towards achieving the commitments and global targets set out in the new United Nations Political Declaration on HIV and AIDS: Ending Inequalities and Getting on Track to End AIDS by 2030, adopted in June 2021, and the linked Sustainable Development Goals.

Since 1996, trachoma has been targeted for elimination as a public health problem worldwide. The active trachoma criterion for national elimination as a public health problem is a TF1–9 < 5%, sustained for at least two years in the absence of antibiotic mass drug administration (MDA), in each form...erly endemic EU. Using A, F and E, health ministries and their partners have made considerable progress towards achieving this criterion in formerly endemic EUs worldwide. In 2002, an estimated 1517 million people lived in EUs in which EU-wide implementation of the A, F and E components of SAFE were thought to be needed for the purposes of global elimination of trachoma as a public health problem; by June 2021, that number had fallen to 136.2 million, a 91% reduction. Approximately 85% of the 136.2 million people living in EUs needing A, F and E in June 2021 were in WHO’s African Region.

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.

This new guidance aims to support programme implementers, coordinators and others in humanitarian settings in their actions to counter suicide and self-harm in humanitarian contexts and to save lives.
A qualitative assessment of knowledge gaps about female genital schistosomiasis among communities living in Schistosoma haematobium endemic districts of Zanzibar and Northwestern Tanzania.
PloS Neglected Tropical Diseases September 30, 2021 https://doi.org/10.1371/journal.pntd.0009789
Schistosoma... haematobium causes urogenital schistosomiasis and is widely distributed in Tanzania. In girls and women, the parasite can cause Female Genital Schistosomiasis (FGS), a gynecological manifestation of schistosomiasis that is highly neglected and overlooked by public health professionals and policy makers. This study explored community members’ knowledge, attitudes and perceptions (KAP) on and health seeking behavior for FGS.

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.

The Indigenous tribe called the Wiwa lives retracted in the Sierra Nevada de Santa Marta, Colombia. Little is known about their health status and whether the health care system in place covers their needs.
Despite the significant role of vector control in national leishmaniasis control programmes, the programmatic community perceives vector control as the weakest component of leishmaniasis control strategies in terms of resources, scientific evidence of the usefulness of interventions and capacity for... quality-assured implementation. Therefore, the main objective of this manual is to provide practical tools, techniques and procedures to strengthen sand fly control and surveillance in order to improve implementation of leishmaniasis control programmes. The manual provides a rationale for programme managers in different geographical regions on the types of vector control interventions to be used in different epidemiological and environmental settings and also how to measure their impact.

Not long ago, on the occasion of the 100th anniversary of the discovery of Chagas disease, several campaigns denounced the scant progress has been made in diffrent spheres- medical, scientific and politcal- but major challanges still remain. This is an appropriate time to celebrate what has been ach...ieved and to take the next step.

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).

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 be a...dded 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.

After five consecutive below-average rains, the humanitarian crisis in the Horn of Africa is expanding and deepening.
Combined with insecurity and macroeconomic volatility, the impact of the drought on food and nutrition security has been devastating. Across Ethiopia, Kenya and Somalia, an estima...ted 22 million people are now acutely food insecure because of the drought. The malnutrition situation is also critical. Some 5.1 million children across drought-affected areas of the three countries are acutely malnourished in 2023, with dire implications for their health, growth and survival. Concerningly, the upcoming March-May 2023 rains are also forecast to be below-average. Should these rains fail, and humanitarian assistance not be delivered at scale, food insecurity will continue to deteriorate.
Regardless of how the 2023 rains perform, extremely high humanitarian needs will persist through 2023 while a full recovery from a drought of this magnitude will take years. To address the devastating drought-induced hunger and malnutrition across the region, WFP is pursuing an integrated dual track approach; meeting immediate life-saving food and nutritional needs while simultaneously building resilience to extreme climate variability.

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.
