Denver Child Under 1 Year Old Contracts Measles After Visit to Mexico, Confirms Colorado Health Department

A baby under 1 year old in Denver has become the second confirmed case of measles in Colorado in 2025, according to the Colorado Department of Public Health and Environment. The baby, who had recently traveled to an area in Mexico where there is an ongoing measles outbreak, is unvaccinated due to being too young to receive the vaccine. Those who visited Denver Health Emergency Department on Bannock Street on April 6 between 10:30 a.m. and 4:30 p.m. may have been exposed to measles and are advised to monitor for symptoms and avoid public gatherings. The first case in Colorado was an unvaccinated adult from Pueblo who had also recently traveled to Mexico, although the specific location in Mexico is not known. This highlights the importance of vaccination to prevent the spread of infectious diseases. The CDPHE is urging anyone who may have been exposed to measles to take precautions and seek medical advice if they develop symptoms. Measles can be a serious illness, especially in young children, and it is crucial to take preventive measures to protect public health.
