Revisiting COVID-19 Communication in Western Africa: A Health Literacy-based Approach to Health Communication.

Adherence to protective measures is a major component of COVID-19 epidemic control. COVID-19 health literacy is a major driver of this adherence, and the evaluation of health literacy levels is the basis for designing an effective communication strategy. We conducted a quantitative socio-anthropological study of the knowledge of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and perception of the prevention messages in Burkina Faso, Cabo Verde, Guinea-Bissau, Ivory Coast, and Sierra Leone. There are widespread erroneous ideas regarding the transmission of and the protection against COVID-19. The majority of people are unaware that asymptomatic individuals can transmit the virus. Knowledge of the risk factors for severe disease is not sufficient, and the majority of individuals fear contracting COVID-19 by visiting a health center. Our study also shows the achievements of communication campaigns on several aspects: almost everybody has heard of the virus and heard or read the messages on the protective measures and a large majority of people think that these measures are effective against COVID-19. Based on these results, we propose a communication strategy that will emphasize that asymptomatic individuals can transmit the virus, emphasize the risk factors, reassure individuals regarding the safety of frequenting health centers, and design specific messages targeting young populations.
