Currently approved therapies for COVID‐19 are mostly limited by their low availability, high costs or the requirement of parenteral administration by trained medical personnel in an in‐hospital setting. Quercetin is a cheap and easily accessible therapeutic option for COVID‐19 patients. However, it has not been evaluated in a systematic review until now. We aimed to conduct a meta‐analysis to assess the effect of quercetin on clinical outcomes in COVID‐19 patients. Various databases including PubMed, the Cochrane Library and Embase were searched from inception until 5 October 2022 and results from six randomized controlled trials (RCTs) were pooled using a random‐effects model. All analyses were conducted using RevMan 5.4 with odds ratio (OR) as the effect measure. Quercetin decreased the risk of intensive care unit admission (OR = 0.31; 95% confidence interval (CI) 0.10–0.99) and the incidence of hospitalisation (OR = 0.25; 95% CI 0.10–0.62) but did not decrease the risk of all‐cause mortality and the rate of no recovery. Quercetin may be of benefit in COVID‐19 patients, especially if administered in its phytosome formulation which greatly enhances its bioavailability but large‐scale RCTs are needed to confirm these findings.

Natural disasters, including droughts, earthquakes, landslides, and floods, cause human mortality, property destruction, and social and economic turmoil. More than 33 million people in Pakistan have been impacted by floods due to the recent heavy rains. Many public hospitals, water treatment plants, and educational institutions have also been damaged or destroyed. Water and vector-borne diseases may have spread more widely due to the floods. A rapid health emergency response must be initiated to treat the injured, stocking healthcare facilities with vital supplies and back up mobile health teams in the impacted areas.
