A measles case in a vaccinated Delta County child has local health officials worried the virus could be quietly circulating in western Colorado. The child, who is under 5, has no recent travel and no known link to other measles patients, yet showed up at local clinics last Wednesday with what turned out to be a confirmed infection. Now, Delta County is flagging two Delta Health facilities as possible exposure sites and asking anyone who passed through to keep a close eye on symptoms.
Where exposures may have happened
Local station KKCO reports the child may have been infectious at Delta Health Urgent Care (296 Stafford Lane) from 5:30 to 8:30 p.m. and at Delta Health Emergency Center (1501 E. 3rd St.) from 6:30 to 9:30 p.m. last Wednesday. KKCO also reports the child had received one dose of the MMR vaccine and had not traveled out of state.
Why public-health officials are concerned
Colorado Department of Public Health and Environment’s school immunization dashboard shows Delta County School District 50J had roughly 86.5% MMR coverage in 2024–25, well below the 95% level public health officials say helps prevent community spread, according to CDPHE. The two-dose MMR series is about 97% effective, and the Centers for Disease Control and Prevention notes that roughly three in every 100 people can still become infected after prolonged exposure. Vaccinated cases are typically milder and less likely to pass the virus to others, but they still keep epidemiologists on their toes.
What to do if you were at the clinics
Delta County and state officials urge anyone who may have been at those clinics during the listed times to watch for measles symptoms for 21 days and to call CDPHE at 720-653-3369 before seeking in-person care to avoid exposing others, KKCO reports. The station notes, in line with local health guidance, that unvaccinated contacts may be eligible for the MMR vaccine if it is given within 72 hours of exposure and that antibody treatment can help if administered within six days. People potentially exposed may develop symptoms through Wednesday, June 17.
State and national picture
Statewide data show Colorado had reported 23 measles cases across seven counties as of early June, according to CDPHE. Nationally, the CDC says the United States has topped roughly 1,900 confirmed infections so far this year. A CDPHE spokesperson told Denver7 that “getting vaccinated is the best way to protect yourself, your family, and your community.”
