The claim
ファウチ氏が「マスクは10%の効果しかない」と発言した
Original review summary
Fauci did say that mask effectiveness at the population level was around 10%, but the review says this referred to limited real-world use, including improper wearing. He also said that properly fitted masks are much more effective, so the claim that he said masks have only 10% effectiveness is misleading.[S1]
