State health officials are becoming increasingly concerned as measles cases began rising across the United States. Nearby states, including Texas and New Mexico, were experiencing significant outbreaks, and with spring break travel fast approaching, the Colorado Department of Public Health and Environment (CDPHE) has issued an urgent reminder for all residents to ensure they were protected against this highly contagious disease.

Dr. Rachel Herlihy, the state’s epidemiologist, explained the seriousness of the situation. While measles had once been nearly eliminated in the U.S. through widespread vaccination efforts, the number of cases had begun to climb again, primarily due to lower vaccination rates. Measles is more than just a rash—it’s a serious illness that can lead to long-term health complications such as hearing loss, brain damage, and, in severe cases, death.

Measles spreads quickly and easily. It can remain in the air for hours and on surfaces for a long time, meaning people can contract it even if they weren’t directly in contact with someone infected. Health officials emphasized that anyone not vaccinated is at risk, and with spring break travel on the horizon, the potential for the disease to spread was high.

The best way to prevent measles is through the MMR vaccine, which protects against measles, mumps, and rubella. The MMR vaccine is highly effective, providing about 93% protection after one dose and 97% after two doses. Health authorities recommend that all children who aren’t immune receive two doses of the vaccine—one between 12 and 15 months and a second at 4 to 6 years of age.

Adults who are unsure of their vaccination history or were vaccinated before 1968 with an older version of the measles vaccine should also consult their healthcare provider about getting vaccinated. The MMR vaccine is available at no or low cost at doctors’ offices, community health centers, pharmacies, and public health clinics.

In addition to vaccination, CDPHE also encouraged residents to stay informed about measles outbreaks, especially if traveling. They recommended checking the CDC’s travel health webpages to keep up-to-date on measles activity in different parts of the country and abroad.

Measles symptoms typically appear 7 to 21 days after exposure and include a high fever, cough, runny nose, red eyes, and a rash that develops a few days after the other symptoms. Anyone who develops these symptoms should contact a healthcare provider immediately and avoid contact with others to prevent further spread.

By taking these precautions—getting vaccinated, staying informed, and recognizing symptoms—Coloradans could help protect themselves and their communities from the ongoing measles threat. Health officials stressed that vaccination was the key to preventing the further spread of the disease and ensuring the health and safety of all residents, especially as travel increases during the spring break.
