With every reversal of Covid-19 guidance, the CDC is losing the battle for public trust
The coronavirus pandemic lays bare how scientific research can be used as a political tool. Over the past few days, the US Centers for Disease Control (CDC) revised and then re-revised its guidance on whether the novel coronavirus can be spread by airborne transmission. On Sept. 18, the agency updated language on its website to state that the virus can spread across distances further than six feet via airborne transmission, especially in poorly ventilated indoor areas.
