RESUMEN

Introduction: in response to the SARS-CoV-2 pandemic that reached Senegal in March 2020, the country has put in place several strategies to contain its spread. The purpose of this study was to describe the epidemiology and the strategies adopted. Méthods: we conducted a descriptive cross-sectional study of confirmed cases of COVID-19 using RT-PCR test in Senegal from March 2, 2020 to September 30, 2021. Data were collected through a literature review and analyzed with R and QGIS software. Proportions and means with standard deviation were calculated. Results: Senegal has recorded a total of 73,782 confirmed cases and 1,859 deaths from SARS-CoV-2. The temporal evolution was marked by three epidemic waves. The epidemic was concentrated in high-density areas such as Dakar (48,656 cases or 66%), in men (sex-ratio 1:13) and in the age group 25-34 years (16.527 cases or 22.4%). The average age of patients was 43 ± 18 years; the national cumulative incidence was 428 per 100,000 population and the overall case fatality rate was 2.5% (1,859/73,782). Some strategies have been implemented, including staff training, restrictive measures, home-based case management and vaccination. Nine point two percent (840,154/9,128,453) of the target population received 2 doses of vaccine. Conclusion: the epidemic was spread more widely within some population groups. We recommend strengthening preventive measures in high-density cities and mobilizing community networks to encourage immunization.

RESUMEN

INTRODUCTION: after a pilot phase, Senegal is the first country in West Africa to introduce cervical cancer vaccine into its Expanded Program on Immunization. Despite the gratuity and availability of the vaccination, coverage was low. The purpose of this study was to identify factors associated with HPV vaccination coverage in girls . METHODS: we conducted a case-control analytical study from 4th to 20th January 2020 in Dakar. The study population consisted of parents or guardians of girls aged 9 to 10. We performed cluster sampling, direct structured interviews and a literature review. Socio-demographic features, parents/guardians' knowledges and information about vaccination procedure were collected using a standardized questionnaire. Logistic regression was used to estimate the odds ratio. RESULTS: during this study, 510 cases and 510 controls and 1020 parents/guardians were interviewed. Significant factors associated with vaccination of girls were: parents/guardians' education (OR=1,97; [1,81-2,25]), knowledge of the disease (OR=3,05; [2,75-4,53], high household income (OR=1,21; [1,13-1,85]), fear of side effects (OR=0,35;[ 0,27-0,44]), reception of messages via internet/social networks (OR=0,54; [0,41-0,92]) and vaccination schedules for the community (OR= 2,12 [1,59-2,64]). CONCLUSION: vaccination of girls can be improved by strengthening parents' knowledge through appropriate channels and a better organization of health services.

RESUMEN

According to the World Health Organization, multidrug-resistant tuberculosis (MDR-TB) represents a major obstacle towards successful TB treatment and control. In Dakar, MDR-TB management began in 2010 with the strengthening of diagnostic resources. The objective of this study was to identify the factors associated with multidrug-resistant tuberculosis in Dakar between 2010 and 2016. We conducted a case-control study from January 10 to February 28, 2017 in tuberculosis centers in Dakar. of 169 cases and 507 controls. We used logistic regression with Epi-info version 7.2.1. to estimate the odds ratios of association. Factors significantly associated with MDR-TB were: residing in a periurban area (ORa=1.8; 95% CI (1.5-4.9); p=0.024), presence of MDR-TB in the entourage of patient (ORa=7.0; 95% CI (6.1-9.5); p=0.002), previous treatment failure (ORa=29.5; 95% CI (27.3-30.1); p=0.000), treatment not directly observed by a health care provider (ORa=4.3; 95% CI (4.1-7,2); p=0.000) and irregularity of treatment (ORa=1.7; 95% CI (0.5-5.4); p=0.037). Focusing interventions on population at-risk will prevent MDR-TB.
