Second Measles Case of 2025 Confirmed in Denver Infant Following Travel to Mexico

Health officials warn potential exposure at Denver Health ER and urge unvaccinated individuals to monitor for symptoms over the next 21 days.

Colorado health authorities have confirmed a second measles case this year, involving an unvaccinated infant from Denver who recently traveled to Chihuahua, Mexico, an area experiencing an outbreak.
The infant visited Denver Health’s emergency department on Sunday, potentially exposing others to the virus between 10:30 a.m. and 4:30 p.m.
Officials advise individuals who were at the ER during that timeframe to monitor for symptoms until April 27 and avoid public gatherings if unvaccinated.
This case is not linked to the earlier Pueblo case in an unvaccinated adult, despite both individuals having traveled to Mexico.
The resurgence of measles in Colorado is part of a broader nationwide outbreak, with over 600 cases reported this year, many tied to declining vaccination rates and an outbreak in Texas.
