Not the first time CDC would be wrong. EDIT: why downvote facts? Recent example on a hot topic: "CDC reverses itself and says guidelines it posted on coronavirus airborne transmission were wrong" https://www.washingtonpost.com/nation/2020/09/21/cdc-covid-a...
Being wrong is the essence of science. By contrast, lyme disease is (1) more than 40 years old, (2) not contagious, and (3) has no political headwinds. There is little reason to distrust CDC on this.
Seems rather naive to presume they had to pass new laws because Lyme has no political headwinds. It has plenty of controversy around it, for better or worse.
