This week, the Colorado Health Department issued a warning about possible measles exposure in metro Denver in late December. In my opinion, Denver parents shouldn’t worry too much.

The biggest risk is to infants who have not received the MMR (measles, mumps, and rubella) vaccine because they may not have the protective antibody. For everyone else, children and adults, the best defense against measles is the vaccination.

When given according to protocol, the vaccination is up to 95 percent effective in children aged 12 months old, up to 98 percent at 15 months old, and up to 99 percent (with 2 doses of vaccine) at one year old and a second dose at 4-6 years old.

Typical signs of measles include a fever on day one (which may increase in intensity step-wise to maximum fever at Day 4), coughing, inflamed, red eyes with drainage, and profuse runny nose. A pink-to-red-color rash will start on Day 4 at the peak of the fever. The rash begins on the neck and face and will spread down to the torso on Day 2 and to the legs around Day 3. (The rash on the face will remain.)

If you think you may be in the area where the exposure was documented, keep children at home, away from crowded areas and schools. Measles is a respiratory illness that is spread by coughing and sneezing and could affect infants who are too young to be vaccinated (those under one year of age), adults with weakened immune systems and those who haven’t been immunized.
