Washington, D.C., 10 November 2025 (PAHO) –The Pan American Health Organization (PAHO) announced today that the Region of the Americas has lost its verification as free from endemic measles transmission.

The decision follows the conclusion of the PAHO Measles, Rubella, and Congenital Rubella Syndrome Elimination Regional Monitoring and Re-Verification Commission, which met in Mexico City from 4 to 7 November 2025 to review the epidemiological situation across the region. The Director of PAHO, Dr. Jarbas Barbosa, received and agreed with the Commission’s report indicating that endemic transmission of measles has been reestablished in Canada, where the virus has circulated for at least 12 months.

As a result, the Americas, which was the first region in the world to eliminate measles twice, has now lost its measles-free status. All other countries continue to maintain their measles elimination status.

“This loss represents a setback—but it is also reversible,” said Dr. Barbosa, “Until measles is eliminated worldwide, our Region will continue to face the risk of reintroduction and spread of the virus among unvaccinated or under-vaccinated populations. However, as we have demonstrated before,…

MP officer raided, Rs 7.6 crore assets found
State anti-corruption investigators launched coordinated operations targeting an official named Sharma after confidential tips pointed to illicit wealth acquisition. Searches conducted across three locations revealed that his holdings exceeded his known income sources by approximately 560 percent. Authorities anticipate the total value of the accumulated wealth could climb further as scrutiny of seized financial and property records continues.

Alzheimer’s may start shrinking two brain regions years before memory loss
Researchers at Johns Hopkins University found that tissue loss begins in the entorhinal cortex and amygdala up to a decade before clinical symptoms appear. These changes are driven by an abnormal accumulation of tau protein and precede deterioration in the hippocampus. Recognizing these initial structural shifts could allow clinicians to diagnose patients earlier and intervene before widespread neurological damage takes hold.

Health advocates warn that decades of progress against the virus could unravel as effective antiretroviral treatments lead a new generation to treat infection as a manageable condition rather than a severe threat. Despite the unprecedented availability of preventative measures like PrEP and PEP, economic strain and uneven service access hinder youth uptake. Without sustained intervention, medical experts caution that regional infection rates could quickly rebound.
