Reviving the US CDC

According to The Washington Post, Deborah Birx, the head of the US COVID-19 Task Force and a former director of the CDC's Global HIV/AIDS Division, cast doubt on the CDC's COVID-19 mortality and case data by reportedly saying: “There is nothing from the CDC that I can trust”. This is an unhelpful statement, but also a shocking indictment of an agency that was once regarded as the gold standard for global disease detection and control. How did an agency that was the first point of contact for many national health authorities facing a public health threat become so ill-prepared to protect the public's health?
