The countdown has already started
The numbers are brutal. In just 20 days in January, Mexico added 1,153 new cases of measles. To give you an idea: in all of 2025 it took almost two months to reach that figure. Now the virus is in all 32 states, with more than 7,600 infections and 25 official deaths.
But here comes the good thing. Or the bad, depending on your level of cynicism.
PAHO’s clock is already ticking
A spokesperson for the Pan American Health Organization made it clear:
“In the case of Mexico, this threshold is met on February 1, 2026.”
It refers to the fatal period: if endemic transmission continues uninterrupted for 12 months or more, Mexico loses its certification as a measles-free country. A title that sounds nice but is, in reality, a health shield.
PAHO will decide in April if the spread has already been reestablished here. Spoiler alert: with these numbers, things look ugly.
And the official numbers are probably just the tip of the iceberg. Rodrigo Romero, from the Mexican Vaccinology Association, releases the fact that hurts:
“Medical literature estimates that for every death there are around a thousand infections.”
Translation: we could be talking about more than 17,000 real cases that never reached an office. People getting sick in silence, without registration.
The solution? The vaccine. It was always the vaccine. But the system showed its cracks just before the disaster: at the end of 2024, only 60% of children and adolescents had the complete second dose (the MMR MMR). The incomplete scheme is a flag salute for the virus.
There is no specific treatment. Just prevention. And that prevention came late and badly.
So get ready. In April we will know if Mexico officially lost a battle it had already won years ago. Collective amnesia about past campaigns and institutional complacency are taking their toll on us. And this bill is measured in lives.
