Amid the Centers for Disease Control and Prevention's (CDC) updated mask guidance and new information coming to light about the origins of COVID-19, experts and Americans alike are questioning the credibility of those calling the shots throughout the pandemic — including the high-profile Dr. Anthony Fauci. "The agency [CDC] has lost all credibility," Dr. Marty Makary, Fox News medical contributor and professor of health policy and management at Johns Hopkins University School of Public Health, said. "They have been consistently delinquent, misrepresenting COVID risk levels. The public sees through the CDC’s flawed guidance on schools, travel and summer camps that use the guise of science. That’s why 52% of Americans no longer trust the CDC."
