Factors Associated with Community Awareness on COVID-19 in a Developing Country: Implications for Optimal Risk Communication

Purpose: New COVID-19 variants pose great challenges in protecting the success of vaccination programs. Awareness of community becomes an important component to prevent the spread of COVID-19. This study aims to analyze people's awareness of COVID-19 and identify the implications for optimal risk communication in Vietnam. Study Methods and Materials: A total of 341 individuals participated in an online cross-sectional study. Community awareness on COVID-19 was examined by using a structured questionnaire. Multivariable Tobit regression was used to examine associated factors with community awareness. Results: Our results indicated high levels of awareness of local COVID-19 situation, transmission risks, and preventive behavioral practices during the first week of social isolation. Higher awareness of local pandemic situation was associated with female respondents (Coef.: 6.19; 95% CI: 0.51; 11.87) and larger family sizes of above 5 people (Coef.: 9.00; -1.00; 19.00). Respondents between 35-44 years old were shown to be less aware of preventive behavioral practices than other age groups, including the group of participants above 44 years old (Coef.: -0.34; 95% CI: -0.67; -0.02). Lastly, participants who were "fairly satisfied" with information resources had awareness levels of preventive behavioral practices lower than that of "unsatisfied" respondents (Coef.: -0.45; 95% CI: 0.74; -0.16). Conclusion: This study offers crucial insights into the pandemic awareness of citizens and risk communication effectiveness during COVID-19 in Vietnam. The study findings shall serve the development of policies and interventions aimed at empowering individuals in the local and global fight against coronavirus.
