Amélioration de la santé des populations en Afrique

n guided by the Human Resources for Health (HRH) Programme (2012-2019) and its successor, the National Strategy for Health Professions Development (NSHPD) (2020-2030). Rwanda has made significant progress in enhancing its skilled health workforce, with notable improvements in the health professional-to-population ratio over the past decade, attaining 13.4 doctors, nurses, midwives, pharmacists, and dentists per 10 000 people in 2022. Despite such progress, health workforce levels remain below national and global recommendations.

Lessons learned from recent public health events such as the COVID-19 pandemic, Ebola virus disease, Zika virus disease outbreaks, and other public health threats, including earthquakes and floods, have highlighted the need for countries to continuously develop, strengthen, and maintain capacities r
...
equired under the International Health Regulations (2005) (IHR (2005)).
Developing capacities for health security in a country requires the engagement of public and private entities across a broad range of sectors, including human and animal health, agriculture, environment, finance, security, emergency management, education, and transportation. The World Health Organization (WHO) is mandated through various resolutions, decisions, and reports of the World Health Assembly, and through the IHR (2005), to provide technical guidance and support to its Member States in developing, strengthening, and maintaining their health systems, including capacities required under the IHR (2005).
For countries to better prevent, prepare for, detect, notify, respond to, and recover from public health emergencies, they must build and maintain IHR core capacities and support the strengthening of health emergency prevention, preparedness, response, and resilience (HEPR) capacities. National Action Plans for Health Security (NAPHS), as capacity development plans, provide the tasks and resources needed to ensure adequate capacities are in place to prevent, detect, respond to, and recover from public health events in a sustainable manner. Investing in the resilience of these capacities within national health systems at national and local levels not only improves national health security but also helps safeguard economic, social, and political developments.

recommandations à l’intention des agents de santé
n October 2019, WHO convened the first meeting of the Buruli ulcer laboratory network (BU-LABNET) in Yaoundé, Cameroon, bringing together 11 laboratories from nine countries at the Pasteur Centre of Cameroon (CPC), the network’s Coordinating Centre. The network was formally established at th

is meeting (1) and its members were those present. The objective of BU LABNET is to improve diagnosis of Buruli ulcer based on polymerase chain reaction (PCR) using standardized testing protocols, involving external quality assurance programmes and sharing knowledge among member laboratories.

The aim of the meeting was to broaden the network’s initiatives. Preliminary work involved integrating laboratory testing for skin NTDs other than Buruli ulcer, such as cutaneous leishmaniasis, mycetoma, leprosy and yaws, while extending the network’s reach to encompass additional laboratories.

WHO Guidelines for the Treatment of Human African Trypanosomiasis. Web Annex B
HAT diagnosis relies on laboratory techniques because clinical signs and symptoms are unspecific. Serodiagnostic tests exist only for Tbg and are based on the detection of specific antibodies, thus they are not confirmatory of infection. With the current low disease prevalence, the positive predicti

ve value of serological tests is particularly low. Field-applicable tools include the card agglutination test for trypanosomiasis (CATT) used mainly in active screening by specialized mobile teams, and the rapid diagnostic tests that are more suitable for individual testing at point-of-care. Confirmation of Tbg infection requires microscopic examination of body fluids necessitating specific training. The best performing methods are laborious and reach 85–95% diagnostic sensitivity when performed by skilled personnel.

Having established the goal of eliminating transmission of gambiense human African trypanosomiasis (g-HAT) to humans, the HAT-e-TAG considered which elements should be developed to assess this goal.
Tsetse traps and targets (insecticide-impregnated screens) function by attracting the flies to a device that collects and/or kills them. Traps can be used for entomological surveillance, and also for control. Targets are simpler than traps, but are not used for surveillance. They are impregnated wit

ies/territories in the Eastern Mediterranean Region are enrolled in the global AMR
surveillance system, and 17 countries/territories reported data in 2024 (for the year 2023). The total number of isolates reported to the system increased sixfold between 2017 and 2022, but the proportion of blood isolates is relatively very low. Most of the data come from public sector laboratories or hospitals, although the private sector has increased its participation in some countries/territories recently. Three pathogens account for three quarters of all the reported pathogens – Escherichia coli
(26%), Klebsiella pneumoniae (23%), and Staphylococcus aureus (22%).
