Knowledge about warning signs and symptoms of COVID-19 in the population of Lima, Peru

Introduction: COVID-19 is a highly infectious disease which may cause great mortality among people with comorbidities. It is thus considered to be a global public health problem. Objective: Evaluate the level of knowledge about warning signs and symptoms of COVID-19 in the population of Lima, Peru. Methods: A cross-sectional descriptive study was conducted. In compliance with the selection criteria, a sample of 307 patients was obtained through a virtual survey applied in the city of Lima from 15 June to 8 July 2020. The tool was validated by expert judgment and Kr-20 (0.71). Bivariate analysis was based on the chi-square test, and the Kruskal-Wallis and Mann-Whitney U statistical tests were used for differences in knowledge means, in view of their non-parametric distribution (Kolmogorov-Smirnov: p < 0.05). A confidence interval of 95 percent and a value of p < 0.05 were considered to be statistically significant. Results: Mean age of participants was 37.5 ± 13.5 years. Prevalence of poor knowledge was 48.2 percent. The warning sign most commonly identified by the population was dyspnea. Of the population surveyed, 55 percent knew of at least one warning sign. The symptoms most frequently recognized by the population were loss of taste, fever, headache and a sore throat. Women were better than men identifying warning signs (p < 0.05). People with an independent job and secondary education had difficulty identifying COVID-19 warning signs (p < 0.05). Conclusion: Nearly half of the population studied had poor knowledge about the warning signs and symptoms of COVID-19. Dyspnea was the warning sign most commonly identified by the population(AU)
