🧵1/N New study published in @jama.com on re-emergence of vaccine-eliminated infectious diseases under declining vaccination in the US. We model long-term risk and conditions for return to endemicity for measles, rubella, polio, & diphtheria. Collab w/ @Mathewkiang.com jamanetwork.com/journals/jam...

As expected, Canada has lost its measles-free status because of the long-running outbreak there. With it goes the #measles elimination status of the entire zone of the Americas, the only division of the #WHO to ever have achieved measles elimination. www.statnews.com/2025/11/10/m...
Canada loses measles elimination status — as does the entire Americas region
Canada has formally lost its measles elimination status, the country’s public health agency announced, triggering the loss of that status throughout all of the Americas.

The thing about outbreaks of infectious diseases is that you can only hide them for so long. Time literally is containment.
And the whistle always blows once people start to die ( in this instance babies). This is why we have public health surveillance and reporting.

Louisiana officials waited months to warn public of whooping cough outbreak
After a whooping cough outbreak killed two infants, Louisiana health officials waited months to officially alert physicians or do public outreach. That's not the typical public health response.
