Interventions Behaviour change communication delivered at the community level in a quasi-experimental manner through small-scale community meetings and home visits. Outcome variables and methods The outcomes of interest were before–after mean and per cent changes in KAP scores. Data were collected from HHs and HMs before and after the intervention and difference-in-differences (DID) analysis technique was applied. Results We found statistically significant (pConclusion Scientifically valid information disseminated at the community level using the health cell approach could bring positive changes in KAP related to COVID-19.
