Coronavirus Disease 2019 (COVID-19) is a new respiratory disease caused by the Severe Acute Respiratory Coronavirus 2 (SARS-CoV-2) which has recently become a pandemic. Gender has a significant influence related to the recovery of COVID-19. Men are prone to longer COVID-19 recovery duration than women since the Coronavirus could linger in the testicles. In addition, older age group is one of independent predictors of delayed COVID-19 recovery. This study aims to determine whether age, gender, and interaction of both affect the duration of COVID-19 recovery. To do this study, a scientific research based on secondary data was conducted by using the Two-way Analysis of Variance (ANOVA) Test. The result shows that age affects the duration of COVID-19 recovery duration with the longest time to be recovered is patients in 26-45 years age category. While, gender and interaction of both factors give no effect for it.
