Novel Coronavirus is defined to be the cause of COVID-19, recently. It's known that COVID-19 goes with excessive immune reaction of human body in severe cases. The investigators hypothesize that quercetin, as a strong scavenger and anti-inflammatory agent, can be effective on both prophylaxis and treatment of COVID-19 cases. Therefore, the aim of this study to evaluate the possible role of quercetin on prophylaxis and treatment of COVID-19.
