The conference for disease detectives hadn’t been held in person for several years because of the pandemic.

@jeffjarvis I'm just glad it's over.
@jeffjarvis The CDC lost a *lot* of credibility during this pandemic. At this point it's hard for me to consider advice from them as much more than medically-themed propaganda.
@jeffjarvis I've continued mask use, albeit on a more calculated basis, until recently when started using one more. They also help a lot with the smog.
