TDR (Tropical Disease Research) Annual Report 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.

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).

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.

Promoting health and preventing disease is a critical component of the effort required to achieve Universal Health Coverage (UHC). to date, efforts to achieve UHC have focused mostly on strengthening health systems and their capacities to provide curative care. However, experience from the COVID-19 ...pandemic has reaffirmed the need for resilient health systems, emphasizing primary health care, including preventive and promotive health and well-being.
Emerging from the eye of the storm as the global health lead agency during the pandemic, WHO is equipped with the required insights and actions for a holistic approach to “building back fairer and better” after COVID-19.
The Healthier Populations (UHP) Cluster in the African Region is designed to support Pillar 3 of WHO’s 13th Global Programme of Work (GPW13) which aims to make 1 billion people healthier by reducing health inequities, preventing diseases and injuries, addressing health determinants, and promoting partnerships for collaborative actions amongst all stakeholders.

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.

Vector-borne diseases are responsible for 17% of the global burden of communicable diseases and more than 500 000 deaths annually. The ambitious global targets for the control of vector-borne diseases come in the context of the (re-)emergence of diseases, increasing resistances to insecticides and u...ncertainty related to the financing of global vector control efforts. The United Nations 2030 Agenda with its related Sustainable Development Goals (SDGs), the New Urban Agenda adopted at the United Nations Conference on Housing and Sustainable Urban Development (Habitat III)
in Quito in 2016 and WHO’s Global vector control response 2017–2030 (WHO, 2017a) emphasize the value of elevating multisectoral actions and strategies that extend beyond the health sector to the core of integrated vector control.
This policy brief underlines the important role housing conditions have in the transmission of vector-borne diseases and showcases interventions and policies the housing sector can contribute to effective, integrated and intersectoral vector-borne diseases management.

The 2023 Country Presence Report provides an overview of what WHO does in countries to advance towards the SDGs and implement GPW13, how we do it, with whom we work, and what is needed to overcome challenges for achieving results and impact in countries.
This publication describes the first WHO public-benefit Target Product Profiles (TPPs) for snakebite antivenoms. It focuses on antivenoms for treatment of snakebite envenoming in sub-Saharan Africa. Four TPPs are described in the document:
Broad spectrum Pan-African polyvalent antivenoms: products ...that are intended for widespread utility throughout sub-Saharan Africa for treatment of envenoming irrespective of the species of snake causing a bite. Monovalent antivenoms for specific use cases: for products for a single species (or genus) of snake (e.g., boomslangs or carpet viper antivenoms).
Syndromic Pan-African polyvalent antivenoms for neurotoxic envenoming: products that are intended for treatment of envenoming by species whose venoms are neurotoxic. Syndromic Pan-African polyvalent antivenoms for non-neurotoxic envenoming: products for snakebite envenoming where the effects are largely haemorrhagic, necrotic or procoagulant.

The Africa Centres for Disease Control and Prevention (Africa CDC) Biosafety and Biosecurity Initiative was launched by the Africa CDC in April 2019 with the aim of strengthening the African Union (AU) Member States’ biosafety and biosecurity systems and enabling them to comply with national and i...nternational requirements for biosafety and biosecurity including the International Health Regulations (IHR) (2005), the Biological Weapons Convention (BWC), and United Nations Security Council Resolution (UNSCR) 1540 and the multi-country Global Health Security Agenda (GHSA). The World Health Organization (WHO) Joint External Evaluation (JEE) and the Global Health Security Index report confirmed the known capacity gaps in biosafety and biosecurity among Africa Union Member (AU).
The regional consultations by Africa CDC conducted between 2019-2021 highlighted the deficiency or limited availability of standardized and regionally recognized training programs in the continent, limiting biosafety and biosecurity capacity building efforts in the region. In response, Africa CDC working with AU Member States developed a home grown, implementable and accessible professional training and certification program that is both recognized and endorsed by AU Member States. The Regional Training and Certification Program for Biosafety and Biosecurity Professionals, for African Biosafety and Biosecurity Professionals (RTCP-BBP) has four (4) areas of specialization, namely
Selection, Installation, Maintenance and Certification of Biological Safety Cabinets
Biorisk Management
Design and Maintenance of Facilities Handling High Risk Pathogens (Biocontainment Engineering)
Biological Waste management
