The CDC has been a disaster during this entire epidemic. Their whole reason for existence is to help prevent disease outbreaks like this, and, if they do occur, help mitigate the damage and keep the public informed on safety precautions to take. First, they screwed up testing early on by claiming they had it covered when it turned out their tests were faulty and they only had a fraction of what was actually needed. Then they spent weeks informing the public that no one needed to wear masks because they did nothing to prevent you from getting the virus. Now they have done a 180 and are telling people to wear masks whenever you are out in public. States are actually REQUIRING people to wear masks now. Either they were lying about the effectiveness of masks the whole time (likely) or they were ignorant of it. The CDC has probably done more damage their reputation than anyone throughout this whole crises. Telling people not to wear masks has to be one of the biggest blunders we've ever had from a government agency. Every doctor and nurse in the country knows how important masks are to prevent the spread of disease, yet the CDC had no idea?
Their models could still be accurate, but my god they've lose a lot of credibility.
