For 75 years, every time any U.S. state has requested epidemiologic assistance (an “Epi-Aid”), CDC sent disease detectives. Now, Wisconsin has asked for help to address newly discovered lead poisoning in Milwaukee. But all CDC experts in lead poisoning were just fired, along with so many others who have spent their working lives dedicated to protecting Americans. As far as I know, this would be the first time the CDC every has not responded to a formal request for assistance from a state.
