Les progrès remarquables réalisés dans la lutte contre la forme à T. b. gambiense reposent sur le dépistage et le traitement curatif, une stratégie qui interrompt la transmission en réduisant le réservoir de parasites chez l’être humain. Parfois, cette
approche a été combinée avec des... activités de lutte antivectorielle. L’objet de ces lignes directrices est donc de la plus haute importance pour la poursuite des progrès en vue de l’élimination de la THA.

Treatment of second-stage gambiense human African trypanosomiasis relied on toxicarsenic-based derivatives for over 50 years. The availability and subsequent use of eflornithine,initially in monotherapy and more recently in combination with nifurtimox (NECT), has drasticallyimproved the pro...gnosis of treated patients. However, NECT logistic and nursing requirementsremain obstacles to its deployment and use in peripheral health structures in rural sub-SaharanAfrica. Two oral compounds, fexinidazole and SCYX-7158, are currently in clinical development.The main scope of this article is to discuss the potential impact of new oral therapies to improvediagnosis-treatment algorithms and patients’access to treatment, and to contribute to reach theobjectives of the recently launched gambiense humanAfrican trypanosomiasis elimination program

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.

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.

To eliminate lymphatic filariasis (LF) by 2020, the World Health Organization (WHO) has launched a campaign against the disease. Since the launch in 2000, significant progress has been made to achieve this ambitious goal. In this article we review the progress and status of the LF programme in Afric...a through the WHO neglected
tropical diseases preventive chemotherapy databank, the Expanded Special Project for Elimination of Neglected Tropical Diseases (ESPEN) portal and other publications. In the African Region there are 35 countries endemic for LF. The Gambia was reclassified as not requiring preventive chemotherapy in 2015, while Togo and Malawi eliminated LF as a public health problem in 2017 and 2020, respectively. Cameroon discontinued mass drug administration (MDA) and transitioned to post-MDA surveillance to validate elimination. The trajectory of coverage continues to accelerate; treatment coverage increased from 0.1% in 2000 to 62.1% in 2018. Geographical coverage has also significantly increased, from 62.7% in 2015 to 78.5% in 2018. In 2019, 23 of 31 countries requiring MDA achieved 100% geographic coverage. Although much remains to be done, morbidity management and disability prevention services have steadily increased in recent years. Vector control interventions conducted by other programmes, particularly malaria vector control, have had a profound effect in stopping transmission in some endemic countries in the region. In conclusion, significant progress has been made in the LF programme
in the region while we identify the key remaining challenges in achieving an Africa free of LF.

Background: The human helminth infections include ascariasis, trichuriasis, hookworm infections, schistosomiasis, lymphatic filariasis (LF) and onchocerciasis. It is estimated that almost 2 billion people worldwide are infected with helminths. Whilst the WHO treatment guidelines for helminth infecti...ons are mostly aimed at controlling morbidity, there has been a recent shift with some countries moving towards goals of disease elimination through mass drug administration, especially for LF and onchocerciasis. However, as prevalence is driven lower, treating entire populations may no longer be the most efficient or cost-effective strategy. Instead, it may be beneficial to identify individuals or demographic groups who are persistently infected, often termed as being “predisposed” to infection, and target treatment at them.
Methods: The authors searched Embase, MEDLINE, Global Health, and Web of Science for all English language, humanbased papers investigating predisposition to helminth infections published up to October 31st, 2017. The varying definitions used to describe predisposition, and the statistical tests used to determine its presence, are summarised. Evidence for predisposition is presented, stratified by helminth species, and risk factors for predisposition to infection are identified and discussed.
Results: In total, 43 papers were identified, summarising results from 34 different studies in 23 countries. Consistent evidence of predisposition to infection with certain species of human helminth was identified. Children were regularly found to experience greater predisposition to Ascaris lumbricoides, Schistosoma mansoni and S. haematobium than adults. Females were found to be more predisposed to A. lumbricoides infection than were males. Household clustering of infection was identified for A. lumbricoides, T. trichiura and S. japonicum. Ascaris lumbricoides and T. trichiura also showed evidence of familial predisposition. Whilst strong evidence for predisposition to hookworm infection was identified, findings with regards to which groups were affected were considerably more varied than for other helminth species.
Conclusion: This review has found consistent evidence of predisposition to heavy (and light) infection for certain human helminth species. However, further research is needed to identify reasons for the reported differences between demographic groups. Molecular epidemiological methods associated with whole genome sequencing to determine ‘who infects whom’ may shed more light on the factors generating predisposition.

Human African trypanosomiasis (HAT), also called sleeping sickness, is a parasitic infection that almost invariably progresses to death, unless treatment is provided. HAT caused devastating epidemics during the 20th century. Thanks to sustained and coordinated efforts during the past 15 years the nu...mber of reported cases has fallen to a historic low. Fewer than 3,000 cases were reported in 2015, and the disease is targeted for elimination by the World Health Organization. Despite recent success, HAT still poses a heavy burden on the rural communities where this highly focal disease occurs, most notably in Central Africa. Since patients are also reported from non-endemic countries outside Africa, HAT should be considered in differential diagnosis for all travellers, tourists, migrants and expatriates who have visited or lived in endemic areas. In the absence of a vaccine, disease control relies on case detection and treatment, and vector control. Available drugs are sub-optimal, but ongoing clinical trials give hope for safer and simpler treatments.

South Sudan has a high burden – among the highest in sub-Saharan Africa – of neglected tropical diseases (NTDs). This adversely affects the health and social and economic well-being of people in the country. The prevention, control and eventual elim...ination of many NTDs depend heavily on improved access to water, sanitation and hygiene (WASH) and, once there is access, on sound sanitation and hygiene practices. This is especially the case in NTD endemic communities.

Neglected tropical diseases (NTDs) are targeted for global control or elimination. Recognising that the populations most in need of medici...nes to target NTDs are those least able to support and sustain them financially, the pharmaceutical industry created mechanisms for donating medicines and expertise to affected countries through partnerships with the WHO, development agencies, non-governmental organisations and philanthropic donors. In the last 30 y, companies have established programmes to donate 17 different medicines to overcome the burden of NTDs.

Neglected tropical diseases (NTDs) is an umbrella term for a diverse group of debilitating infections that represent the most common afflictions for 2.7 billion people living on less than US$2 per day. Major efforts have recently re-focused attention on NTDs, including structured advocacy by the Bil...l and Melinda Gates Foundation, technical and political support by WHO and large-scale drug donation programs by pharmaceutical companies. An analysis of the Official Development Assistance (ODA) for NTDs in 2009 showed that Development Assistance Committee members and multilateral donors had largely ignored funding NTD control projects. This study reviews the changes since 2009 and finds an increased engagement by pharmaceutical manufacturers through drug donation programs substantially increased by the ‘London Declaration’ in 2012, a focused effort of 77 public and private partners on control or elimination of the 10 most common NTDs, but no increase in ODA for NTDs between 2008 and 2012. The allocation of ODA still does not reflect the respective importance of these diseases.

Africa CDC Institute of Pathogen Genomics (IPG) was launched in November 2019 and operates under the Division of Laboratory Systems and Networks.
IPG coordinate the implementation of molecular diagnostics, pathogen genomics and bioinformatics in National Public Health Institutions (NPHIs) and/or Re...fe-
-rence Laboratories (NRLs) across Africa.
Africa CDC and APHF are coordinating a continental initiative to maximize the benefits of molecular approaches and pathogen genomics for more effective
outbreak preparedness, prevention, response, and for the control and elimination of endemic diseases in Africa. One of Africa CDC’s flagship initiative is the Africa
Pathogen Genomics Initiative (Africa PGI), a partnership that aims to strengthen laboratory systems and enhance genomic surveillance by equipping the continent’s
public health institutions with the tools, training, and data infrastructure.
About the Project
In 2023, 166 outbreaks and public health events were reported in Africa. This calls for a resilient laboratory systems for timely detection and reporting of current and future outbreaks. This project aims to scale up molecular diagnostic and genomic sequencing-based detection and characterization of outbreaks.
Africa CDC is working with Member States to develop guidance, diagnostic algorithm, training and capacity building to enable outbreak detection, and reporting to inform public health response.

The Global Leprosy Strategy 2021–2030 “Towards zero leprosy” was developed through a broad consultative process with all major stakeholders during 2019 and 2020. Valuable inputs were provided by national leprosy programme managers, technical agencies, public health and leprosy experts, funding... agencies and persons or members of communities directly affected by leprosy.
The Strategy aims to contribute to achieving the Sustainable Development Goals. It is structured along four pillars:
(i) implement integrated, country-owned zero leprosy road maps in all endemic countries;
(ii) scale up leprosy prevention alongside integrated active case detection;
(iii) manage leprosy and its complications and prevent new disability; and
(iv) combat stigma and ensure human rights are respected. Interruption of transmission and elimination of disease are at the core of the Strategy.
