Abstract

Introduction: Guinea experienced two pertussis epidemics in two health Regions of the country between 2022 and 2023. The first occurred in two health districts in the Labe region and the second in the Lola health district in Nzerekore. The aim of the study was to compare the two responses and determine the epidemiological, clinical, and evolutionary characteristics of pertussis cases in concerned children, and to identify the risk factors for the commencement of the disease. We conducted a descriptive and comparative cross-sectional study of the response to the two pertussis epidemics from 03 to 16 January 2023 in the prefectures of Lelouma and Mali and from 15 to 25 April 2023 in the prefecture of Lola. Our study population was children suspected of having pertussis living in these localities. Results: A total of 146 suspected cases of pertussis were recorded out of 5,831 inhabitants of the affected localities (the overall attack rate was 34 cases per 1,000 inhabitants), with one case of death. During the first epidemic, we recorded 83 cases of Pertussis cough in Linsan Saran and 13 cases in Dougountouny. The median age was 4 years and 54% were boys. The epidemic began on 21 November 2022 in Linsan Saran and cases then appeared intermittently until 20 January 2023. The second epidemic recorded 50 cases, of which 5 were confirmed and one death was reported in the village of Gbee. The epidemic began on 18 March 2023 and ended on 25 April 2023. The lessons learnt from the first epidemic enabled the health authorities to bring the second epidemic under control quickly, and to prevent any further outbreaks and prevent it from spreading to other localities in the health district. In terms of financial resources deployed to contain the two epidemics, out of a total of GNF 261,256,448, 62.78% was used for the second epidemic, compared with 37.22% for the first. Conclusion: Our study shows that during both epidemics, the disease affected children with a median age of 4 and 3 years respectively. The risk factors for the occurrence of pertussis were low vaccination coverage among children with the disease, a history of contact with cases and promiscuity. The two epidemics were studied using the surveillance system set up by the Ministry of Health and implemented by the health district management teams.
