Assessment of knowledge, perception, preventive practices and effects of COVID-19 among Nigerians: a cross-sectional study

Introduction: the coronavirus disease 2019 (COVID-19) has become a disease of global public health concern. The current cumulative cases in Nigeria are high. The effective control of the pandemic is dependent on knowledge, attitude and willingness of people to adapt their life to the new reality. The purpose of this study is to determine the knowledge, perception, preventive practice, and effect of COVID-19 on the respondents. Methods: we conducted a cross sectional, online survey-based study (Google form) from May 25th, 2020 to June 25th, 2020. The survey questionnaire consisted of demographic characteristics, 13 items on knowledge, 6 items on preventive practices, 13 items on perception. Descriptive statistics, t-test, one-way ANOVA and bivariate logistic regression were carried out. Results: the correct overall knowledge was 98.03% with average score of 11.7 +/- 1.0 (9-13). Knowledge scores were comparable in all demographics except marital status. Most of the participants practiced preventive procedures such as wearing face mask (95.1%), use of alcohol based hand sanitizer (78.9%), avoidance of worship centers (62.4%) and regular hand washing. There were several perceptions ranging from rumors to unfounded scientific claims. Gender, level of education, monthly income and Christian denomination were predictors of use of hand sanitizer while age, level of education, monthly income, Christian denomination and region were predictors of attendance of worship centers during lockdown. Conclusion: the results of this study suggest government should gain trust of citizens to translate knowledge to practice and full compliance of regulations.
