Measles Rates Increase in the United States
The Centers for Disease Control and Prevention (CDC) reports that cases of measles in the United States have increased. The Centers for Disease Control and Prevention (CDC) reports that between January 1 and February 14, 2019, 127 individual cases of measles have been confirmed in 10 states. The states that have reported cases to CDC are California, Colorado, Connecticut, Georgia, Illinois, Kentucky, New York, Oregon, Texas, and Washington. This is the greatest number of reported cases in a calendar year since 2000, when measles elimination (i.e., the absence of continuous disease transmission for 12 months or more in a specific geographic area) was documented in the United States.
Approximately 9 of 10 susceptible persons with close contact with a measles patient will develop measles.
Approximately 30% of patients who have measles develop one or more complications.
More than 95% of individuals who receive a single dose of MMR will develop immunity to all 3 viruses (measles, mumps, and rubella).
Keeping immunization rates high is the best way to prevent more outbreaks. Measles vaccination is 95%-98% effective after one dose, and 99% effective after two doses. You can make sure you are protected one of three ways:
Measles vaccine is included in the MMR (measles, mumps, rubella) and MMRV (measles, mumps, rubella, varicella) vaccines. The first dose of this vaccine is routinely given at 12 months of age, with a second dose at 4 – 6 years of age. If it has not already been done, the second dose is often given when the child starts kindergarten. It is one of the required immunizations for school in North Dakota. Therefore, unless your child is behind on the immunization schedule or you have declined to immunize your child, children in school are generally protected.
Adults born in 1957 or after:
To be certain they are protected, adults in this age group should have a record of vaccination. Some early vaccinations may have contained only the measles vaccine, and may not have been the MMR combination. Those attending college or other secondary educational institutions, persons who work in medical facilities, and international travelers should receive two doses of MMR. Measles vaccination is 95%-98% effective after one dose. Adults who have had only one dose may choose to have a second dose.
Adults born before 1957:
In general, adults born before 1957 are likely to have had or been exposed to measles during childhood and so are typically assumed to be immune. During an outbreak, these adults may want to get the MMR vaccine to ensure that they are protected. Those attending college or other secondary educational institutions, persons who work in medical facilities, and international travelers should receive two doses of MMR.
