CNN host Michael Smerconish confronted Dr. Anthony Fauci on Saturday over a recent study that questioned the efficacy of face masks during the COVID-19 pandemic.
What about the study?
In January, the Cochrane institute released a new systematic review studying the impacts of "physical interventions" to slow the spread of respiratory viruses. The study concluded that wearing masks "probably makes little or no difference to the outcome" on flu-like or COVID-like illness or laboratory-confirmed flu or COVID-19 compared to not wearing masks.
Oxford epidemiologist Tom Jefferson, the study's first author, said after the study was published, "There is just no evidence that [masks] make any difference."
