Overview

• 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.
