Since 2000, concerted efforts by national programmes, supported by public–private partnerships, nongovernmental organizations, donors and academia under the auspices and coordination of the World Health Organization (WHO), have produced important achievements in the control of human African trypan...osomiasis (HAT). As a consequence, the disease was targeted for elimination as a public health problem by 2020. The Sixty-sixth World Health Assembly endorsed this goal in resolution WHA66.12 on neglected tropical diseases, adopted in 2013.
National sleeping sickness control programmes (NSSCPs) are core to progressing control of the disease and in adapting to the different epidemiological situations. The involvement of different partners, as well as the support and trust of long-term donors, has been crucial for the achievements.

Human African trypanosomiasis (HAT) has been an alarming global public health issue. The disease affects mainly poor and marginalized people in low-resource settings and is caused by two subspecies of haemoflagellate parasite, Trypanosoma brucei and transmitted by tsetse flies. Progress made in HAT ...control during the past decade has prompted increasing global dialogue on its elimination and eradication. The disease is targeted by the World Health Organization (WHO) for elimination as a public health problem by 2020 and to terminate its transmission globally by 2030, along-side other Neglected Tropical Diseases (NTD). Several methods have been used to control tsetse flies and the disease transmitted by them. Old and new tools to control the disease are available with constraints.
Currently, there are no vaccines available. Efforts towards intervention to control the disease over the past decade have seen considerable progress and remarkable success with incidence dropping progressively, reversing the upward trend of reported cases. This gives credence in a real progress in its elimination. This study reviews various control measures, progress and a highlight of control issues, vector and parasite barriers that may have been hindering progress towards its elimination.

Chromoblastomycosis (CBM), represents one of the primary implantation mycoses caused by melanized fungi widely found in nature. It is characterized as a Neglected Tropical Disease (NTD) and mainly affects populations living in poverty with significant morbidity, including stigma and discrimination.
The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

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.

The desired impact of the OH JPA is a world better able to prevent, predict, detect and
respond to health threats and improve the health of humans, animals, plants and the
environment while contributing to sustainable development. The OH JPA aims to work
towards this vision in the following way:
...
• Provide a framework for action and propose a set of activities the four organizations
can offer together to advance and sustainably scale up One Health.
• Provide upstream policy and legislative advice and technical assistance, to help
set national targets and priorities across the sectors for the development and
implementation of One Health legislation, initiatives and programmes.
• Take stock of existing cross-sectoral global and regional initiatives around One
Health, identify and advise on synergies and overlaps, and support coordination.
• Mobilize and make better use of resources across sectors, disciplines and
stakeholders.
• The OH JPA is guided by a theory of change and makes use of One Health principles
to strengthen collaboration, communication, capacity building and coordination

Rabies has an enormous impact on both agriculture and conservation biology, but its greatest burden is undeniably on public health. As such, routine methods for rapid risk assessment after human exposures to rabies as well as applications for laboratory-based surveillance, production of biologicals ...and management of this infectious disease are critical. Given its mandate to improve human health and control disease among its Member States, WHO has led the production of this fifth edition of Laboratory techniques in rabies.

Chagas disease is currently endemic and also predicted to be at increased transmission risk under future climate change scenarios. Similarly, an expansion of areas in the United States at increased risk for Chagas disease transmission is also expected over the next several decades under climate chan...ge scenarios. Of particular interest is the predicted northern shift of triatomine species to central regions of the United States with historically unsuitable climates for T. cruzi vectors. The weight of evidence regarding the influences climate change may pose on T. cruzi vector species distributions demonstrates the sensitivity of Chagas disease transmission to future climate variability. In order to advance forecasts for the impact climate change may have on Chagas disease transmission in the Americas, it is imperative to
further develop, utilize, and perhaps combine predictive species distribution modeling approaches that integrate accurate, long term data on climate variables, vector species distributions, Chagas disease incidence, as well as other socio-ecological variables.

It is impossible to address the many complex needs of respiratory virus surveillance with a single surveillance system. Multiple systems, investigations and studies must each be fit-for-purpose to specific priority surveillance objectives, and only together can they provide essential information to ...policy-makers. In essence, each surveillance approach fit together as “tiles in a mosaic” that provides a complete picture of respiratory viruses and the impact of associated illnesses and interventions at the country level. This mosaic framework demonstrates how surveillance approaches may be implemented as coordinated and collaborative systems, well-matched to specific priority objectives.

The Event-based Surveillance Framework is intended to be used by authorities and agencies responsible for
surveillance and response. This framework serves as an outline to guide stakeholders interested in implementing
event-based surveillance (EBS) using a multisectoral, One Health approach. To ...that end, the document is arranged
in interlinked chapters and annexes that can be modified and adapted, as needed, by users.
This is a revised version of the original “Framework for Event-based Surveillance” that was published in 2018. This
framework does not replace any other available EBS materials, but rather builds on existing relevant or related
documents and serves as a practical guide for the implementation of EBS in Africa. This framework is aligned with
the third edition of the WHO Joint External Evaluation for the following indicators: strengthened early warning
surveillance systems that are able to detect events of significance for public health and health security (Indicator
D2.1); improved communication and collaboration across sectors and between National, intermediate and local
public health response levels of authority regarding surveillance of events of public health significance (Indicator
D2.2); and improved national and intermediate-level capacity to analyse data (Indicator D2.3). As countries begin
to implement and demonstrate EBS functionality they will ensure an increase in JEE scores and progress towards
meeting the requirements outlined in the IHR3F
Additionally, in African Union Member States that have adopted the Integrated Disease Surveillance and
Response (IDSR) strategy, this document is a complement to and can enhance the implementation of IDSR,
especially for the 3rd edition (2019) that includes components related to EBS.

As a high-burden neglected tropical disease, soil-transmitted helminth (STH) infections remain a major problem in the world, especially among children under five years of age. Since young children are at high risk of being infected, STH infection can have a long-term negative impact on their life, i...ncluding impaired growth and development. Stunting, a form of malnutrition in young children, has been long assumed as one of the risk factors in acquiring the STH infections. However, the studies on STH infection in children under five with stunting have been lacking, resulting in poor identification of the risk. Accordingly, we collected and reviewed existing related research articles to provide an overview of STH infection in a susceptible population of stunted children under five years of age in terms of prevalence and risk factors. There were 17 studies included in this review related to infection with Ascaris lumbricoides, Trichuris trichiura, hookworm, and Strongyloides stercoralis from various countries. The prevalence of STH infection in stunted children ranged from 12.5% to 56.5%. Increased inflammatory markers and intestinal microbiota dysbiosis might have increased the intensity of STH infection in stunted children that caused impairment in the immune system. While the age from 2 to 5 years along with poor hygiene and sanitation has shown to be the most common risk factors of STH infections in stunted children; currently there are no studies that show direct results of stunting as a risk factor for STH infection. While stunting itself may affect the pathogenesis of STH infection, further research on stunting as a risk factor for STH infection is encouraged.
