With the absence of immunological, pharmacological or any other known medical interventions, the change in norms, behaviour and attitude of the public remains the only possible way that may be considered for prevention and suppression of COVID-19. This disease, which has morphed into a global pandemic, has mobilized outrageous outpouring action worldwide. Despite international and local media attention coupled with overwhelming new facts replete with misinformation and disinformation on COVID-19 from many channels; including interpersonal and social media, efforts to scale up control measures have yielded mixed results. The government and Kenyan media have reported several cases in which the public and leaders flouted these measures thus putting themselves at risk of contracting or spreading the virus. The overarching question is: does fear-arousing communication really matter in behaviour change particularly during a global pandemic of the magnitude of COVID-19? This qualitative study therefore examined the effects of COVID-19 messages on health behaviour change among residents living in the Municipality of Busia, one of the towns that have recorded the highest incidences of confirmed COVID-19 cases as informed by the Extended Parallel Process and Health Belief behavioural change models. Focus group discussions and in-depth interviews were carried out to establish threat and coping appraisal as a result of COVID-19 messages received from different sources. The study employed a risk behaviour diagnosis assessment that focused on two components of health risk messages, that is, threat and recommended response that addresses efficacy issues. This study found out that despite universal knowledge of COVID-19 and prevention methods, perceived threat especially perceived vulnerability to the virus was low due to misinformation, disinformation and disjointed communication.
