RFK Jr.’s attempt to argue that there has not been continuous transmission of measles in the U.S. for a year seems to hinge on Utah.
Recall that the index case in Utah refused to speak to the health department, so the truth is that we will never know if they had a connection to TX.

Measles elimination is an aspirational goal. It is not a bond rating. If the US loses its measles elimination status it will be public confirmation that we're is on the wrong track to protect Americans. But so is the fact that 3 people have died in the deadliest measles outbreak in 25 years. 1/
