Assessment of adherence to public health measures and their impact on the COVID-19 outbreak in Benin Republic, West Africa

Introduction: following the global COVID-19 outbreak, the government of Benin implemented preventive measures to stall viral transmission. We sought to evaluate adherence of the Beninese people to these preventive measures, in order to identify predictors of poor adherence and adapt the national response to COVID-19. Methods: two consecutive online surveys were conducted between May and August 2020. Four hundred and sixty two and 507 adult participants aged 18 years and above responded to the first and second survey respectively, with 70% being males Results: more than 98% of respondents reported wearing face masks. A five-point adherence score was constituted by scoring observance to key preventive measures (mask use, physical distancing, hand hygiene, coughing hygiene and avoiding to touch one ' s face). We observed that the mean adherence scores were fairly stable over time, respectively 4.08 and 4.03 during the first and second survey (p=0.439). Increasing age (aOR=1.043, 95% CI: 1.026 -1.061; p<0.001) and obtaining COVID-19 information from official sources (aOR=1.628, 95% CI: 1.275 -2.081; p<0.001) were significantly associated with higher adherence scores in a multivariable model. Conclusion: these findings suggest that a wide dissemination of adequate information about COVID-19 would increase adherence, and that targeted efforts should be directed towards increasing the compliance to preventive measures among the younger age groups
