Perception des acteurs de l'approche « Une Seule Santé ¼ de la sécurité sanitaire mondiale au Bénin.

INTRODUCTION: The perception of human resources is essential for their commitment in strengthening health security. The study assessed the perception of the “one health” approach stakeholders on global health security in Benin. METHODS: The study was qualitative, cross-sectional and quantitative. Non-probability sampling method with purposive choice were used to select 55 actors from health, veterinary and environmental sectors, and from community. Individual interviews and three focus groups were used to collect data; The content analysis was used to perform thematic groupings. RESULTS: Respondents had a good knowledge of threats (73%), events (59%) and information mechanisms (68%). The health security environment was characterized by the absence of an integrated mechanism for information sharing, episodic and unbalanced collaboration, a difference between the level of organization of the sectors with health sector perceived as better organized by 92% of respondents. The environment is presented as the sector requiring major reinforcements. Community involvement was also episodic. The sectors were dependent on the partners. The community was not involved in setting priorities and lacked commitment to health security. The regulatory component is insufficient, and no law enshrines the international health regulations as a reference. For 60% of respondents, health security was a reality in Benin and 21% were satisfied with it. Respondents had a good perception of health security and its challenges in Benin. CONCLUSION: The strengthening of legislation and collaboration is necessary for the improvement of global health security in Benin.

Évaluation des capacités de détection des menaces infectieuses aux points d'entrée au Bénin.

BACKGROUND: The International Health Regulation requires countries to establish measures at border entry points to prevent the spread of infectious threats across borders. OBJECTIVE: This study assessed the capacity for the detection of infectious threats to global health security at entry points in Benin in 2021. METHODS: This cross-sectional and descriptive study was conducted at 17 borders. Collection techniques included individual interview, observation, and document exploitation. Each entry point capacity was rated good if the entry point met at least 80 % of input criteria and 80 % of process criteria and 80 % of output criteria. The overall detection capacity was rated good if at least 80% of entry points had good capacity. Otherwise, the capacity was deemed insufficient. RESULTS: The capacity for the detection of infectious threats at entry points in Benin was insufficient. There was no entry point (0.0%) that reach 80% of inputs criteria. 11.8% of them reached 80% of process criteria and 5.9% reached 80% of output criteria. There was no entry point with good detection capacity. The travelers’ screening was not systematic. Only 19.4% of human travelers, 12.8% of food loads and 0.1% of animals were screened the day before the survey. Two alerts among human travelers, four among animals and one food safety alerts were detected. Health teams were present in all designated entry points, but they were only focused on Covid-19. CONCLUSION: Strengthening the detection system and extending it to other threats is necessary to improve the detection capacity at entry points.

Évaluation des capacités du système de laboratoires biologiques pour la détection des menaces infectieuses au Bénin.

Background : International Health Regulations require countries to establish laboratory systems for rapid and safe confirmation of public health emergencies.Objective : This study assessed the capacity of the National Laboratory System for the detection of infectious threats to global health security in Benin.Method : The study was descriptive, cross-sectional, and evaluative. The targets were laboratories performing the confirmation of infectious threats. The sampling method was non-probabilistic with the reasoned choice of 74 laboratories. Four collection tools were used. The World Health Organization’s laboratory assessment tool for health facilities was used to assess the national public health laboratory. The assessment was based on the capacities of peripheric laboratories and of the national reference laboratory. The capacity was rated good if at least 80% of peripheric laboratories met at least 80% of the criteria and if the national public health laboratory had an average indicator of at least 80%. Otherwise, the capacity was rated insufficient.Results : The national laboratory system capacity was insufficient. Only 54% of peripheric laboratories had good capacity. The national reference laboratory had an average indicator of 71%. In this reference laboratory, specimen collection and transport, laboratory testing performance, consumables and reagents, and public health functions had the best scores, above 80%. Biorisk management, organization and management, and documents had the lowest scores. In peripheric laboratories, the testing performance was the only domain with good capacity.Conclusion : To ensure effective Global Health Security in Benin, a National Laboratory System capacity improvement strategic plan need to be developed and implemented.

Main challenges of the detection in the context of global health security: systematic review of Joint External Evaluation (JEE) reports.

Introduction: since 2016, Joint External Evaluation (JEE) missions have been organized in various countries. This systematic review of the JEE reports is intended to identify the main challenges (MC) of detection in WHO regions. Methods: we accessed JEE reports on the WHO website. Challenge was defined as a variable of the indicators of detection where there was a need of improvement. MC was a challenge common to at least one-third of countries in each region and globally. For consistency, we assessed challenges reported under "Areas which need strengthening/challenges" in reports. Results: we analyzed 96 JEE reports. African Region (91.7%), Eastern Mediterranean Region (80.9%) and South East Asia Region (72.7%) had the highest rates of JEE completion. The MC were 24 in European Region, 26 in Mediterranean Region, 30 in Western Pacific Region, 33 in South East Asia Region and 34 in African Region. 24 MCs were identified at global level. National laboratory system and Real time surveillance had the highest number of MC. Eleven MCs were common to all WHO regions and global level. These include insufficient capacity for core test confirmation, insufficient specimen referral system, weak quality management system, issues in laboratories licensing and accreditation, weak data management, weak electronic reporting system, absence /weak mechanism of information exchange between International Health Regulation and animal health focal points, insufficient health professional specialists, the need of workforce strategy, the need of field epidemiology and insufficient workforce retention capacity. Conclusion: the MCs identified should be addressed through a global approach.

Epidemiological characteristics of a protracted and widespread measles outbreak in the Democratic Republic of Congo, 2018 - 2020.

Introduction: measles is a highly contagious viral disease. Since 2011, the Democratic Republic of Congo (DR Congo) has had the first dose measles vaccination coverage of less than 80% according to the World Health Organization - United Nations International Children's Emergency Fund (WHO-UNICEF) coverage estimates, and measles mass vaccination coverage of less than the required coverage level of 95% by survey. Starting in August 2018, the country experienced an increase in measles case reports which continued through to early 2020. Epidemiological aspects of the outbreak are described in this article. Methods: we analysed aggregate weekly passive surveillance data from the DR Congo for the years 2018 - 2020 to understand the trends of occurrence of suspected measles cases. We also analysed the measles case-based surveillance database to understand the epidemiological characteristics of confirmed cases of measles and rubella during the same period of time. Results: a total of 458,156 suspected measles cases and 8,127 deaths were reported between 1st January 2018 and 31st December 2020, with the majority of cases and deaths reported in 2019. Only 2.9% of these cases were reported through the case-based surveillance system, with 31,639 cases being confirmed as measles by the laboratory, by epidemiological linkage and on clinical compatibility. Children less than 5 years of age were most affected with a cumulative incidence of 960 cases per 1,000,000 inhabitants. Only 41% of the confirmed cases were vaccinated. Maindombe and Tshopo provinces had the highest cumulative incidence levels. There was a distinct geographic progression of the outbreak between provinces during the course of the three years. A total of 1760 lab confirmed rubella cases were confirmed in various provinces among the cases investigated with blood specimens, 93% of whom were less than 15 years of age. Conclusion: the recent gaps in vaccination coverage, the age pattern of confirmed cases and the lack of vaccination history in the majority of cases is suggestive of failure to vaccinate as the likely cause of this large and protracted outbreak. Efforts to improve vaccination coverage and the measles surveillance system are needed in order to prevent the occurrence of future outbreaks and to avert measles-related deaths.

Assessment of the Biosafety and Biosecurity in the Reference Veterinary Laboratory of Parakou in Benin.

Optimal biosafety and biosecurity are major requirements of global health security. This study assessed the biorisk management in the reference veterinary laboratory of Parakou (Benin). The study was cross-sectional, descriptive, and evaluative. The non-probability sampling method with the reasoned choice was used. The Food and Agriculture Organization laboratory mapping tool-safety was used to collect information from the laboratory team. Group discussion, working environment observation, and document exploitation were the data collection techniques. The biorisk management was rated good if the average indicator of the laboratory reached at least 80%. Otherwise, the biorisk management was rated insufficient. The overall laboratory biosafety and biosecurity score was insufficient (42.4%). Per area, the scores were 26.7% for engineering, 33.3% for administration, 53.8% for personal protective equipment, and 62.3% for the operational. There was no area or category score that reached 80%. Containment, waste disposal, and personal protective equipment disposal were the best performing categories with a score above 60%. The laboratory has no biosafety and accident prevention program. Its premises require renovation. The standard operating procedures for biosafety are not yet finalized, and the training mechanism is not optimal. Therefore, strong advocacy and implementation of a biorisk management improvement plan appear as urgent corrective actions which are required to help the reference veterinary laboratory of Parakou in its task to protect the livestock and, ultimately, the people of Benin from dangerous diseases and emerging pathogens.

Challenges related to resources mobilization for measles outbreak response: Madagascar experience during the 2018-2019 measles outbreak.

INTRODUCTION: on October 4th, 2018, a measles outbreak was declared in Madagascar. This study describes challenges related to resources mobilization for the outbreak response. METHODS: data were collected using minutes of coordination committee meetings, activities reports, operational action plans and situation reports. RESULTS: the total cost of the outbreak response was estimated to US$ 11,281,381. Operational cost was the leading cost driver (42.45%) followed by vaccine cost (33.74%). Cases management, epidemiological surveillance, communication and social mobilization and routine immunization strengthening represented 23.81% of the total cost. The main funder of the outbreak response was the measles and rubella initiative. CONCLUSION: good coordination, open dialogue, good use of financial resources and accountability of government and partners have enabled to gain the confidence of national and international donors.

Madagascar 2018-2019 measles outbreak response: main strategic areas.

INTRODUCTION: on October 4th, 2018, a measles outbreak was declared in Madagascar. This study describes the outbreak response in terms of coordination, case management, vaccination response and epidemiological surveillance. METHODS: data were collected using a line list and vaccination tally sheet. Serum samples were collected within 30 days of rash onset for laboratory testing; confirmation was made by detection of measles immunoglobulin M antibody. RESULTS: from September 2018 to May 2019, a total of 146,277 measles cases were reported which included 1394 (1%) laboratory-confirmed cases and 144,883 (99%) epidemiological link-confirmed cases. The outbreak affected equally males (72,917 cases; 49.85%) and females (73,233 cases; 50.06%). The sex was not specified for 127 (0.09%) cases. Case fatality rate and attack rate were high among children less than 5 years. Responses interventions include effective coordination, free of charge case management, reactive vaccination, strengthened real-time surveillance, communication and community engagement and the revitalization of the routine immunization. Reactive vaccination was implemented in different phases. A total of 7,265,990 children aged from 6 months to 9 years were vaccinated. Post campaign survey coverage was 95%, 96% and 97% for phase 1, 2, 3 respectively. CONCLUSION: elimination of measles will be challenging in Madagascar because of low routine immunization coverage and the absence of a second dose of measles vaccine in the routine immunization schedule.

Measles outbreak in 2018-2019, Madagascar: epidemiology and public health implications.

INTRODUCTION: In October 4th, 2018, a measles outbreak was declared in Madagascar. This study describes the epidemiology of the outbreak and determines public health implications for measles elimination in Madagascar. METHODS: Data have been collected using line list developed for the outbreak. Serum samples were collected within 30 days of rash onset for laboratory testing; confirmation was made by detection of measles immunoglobulin M (IgM) antibody. RESULTS: A total of 2,930 samples were analysed in the laboratory among which 1,086 (37%) were laboratory confirmed. Measles cases age ranged from a minimum of 1 month to a maximum of 88 years. The median and the mean were 7 years and 9 years respectively. Children between 1 to 9 years accounted for 50.6% of measles cases. Attack rate (39,014 per 1,000,000 inhabitants) and case fatality rate (1.2%) were highest among children aged 9-11 months. A total of 67.2% cases were unvaccinated. As of March 14th, 2019, all the 22 regions and 105 (92%) health districts out of 114 were affected by the measles outbreak in Madagascar. CONCLUSION: Measles outbreak in Madagascar showed that the country is not on the track to achieve the goal of measles elimination by 2020.
