Why Is This Important?

Measles is a highly contagious viral disease that can be particularly serious in infants and adults. Although measles usually lasts only one to two weeks, it can cause serious complications such as pneumonia, ear infections, and encephalitis (inflammation of the brain). In very young or malnourished patients, blindness can occur. Measles is a common and often fatal disease in developing countries. The World Health Organization (WHO) reports that even though a safe and cost-effective vaccine is available, in 2017, there were 110,000 measles deaths globally, mostly among children under the age of five. Before the measles vaccine was introduced in 1963, more than a half million cases of measles were reported annually in the United States. Due to intensive efforts to vaccinate preschool aged children, reported cases of measles have declined rapidly over time. The United States has established the goal of eliminating the transmission of endemic measles strains.

How Are We Doing?

In 1996, the Utah childhood immunization rate was the lowest in the country. Since that time, the immunization rate in Utah has improved. The recent low rates of measles infection in Utah can be attributed both to improved immunization rates, as well as the natural cycle of the disease. However, despite higher immunization rates in Utah than in previous years, there is still more work to be done in this regard. For example, in 2011, Utah experienced an outbreak of measles with 13 cases reported. Measles was introduced into Utah through foreign travel by an unvaccinated adolescent. Two of the 13 cases were known to be vaccinated, and the remaining 11 were either unvaccinated, partially vaccinated, or documentation was not found. Two more measles outbreaks were subsequently identified in 2014 (3 cases) and 2017 (3 cases) in Utah; the majority of cases in these outbreaks were unvaccinated. No measles cases were reported in Utah in 2018 or 2019. In 2019, the Utah MMR vaccination rate among children aged 24 months was 90.5%, compared to 89.9% for the U.S. In the U.S., 17 measles outbreaks were reported in 2018 resulting in 372 cases. Three outbreaks in New York State, New York City, and New Jersey, respectively, contributed to most of the cases. Cases in those states occurred primarily among unvaccinated people in Orthodox Jewish communities. These outbreaks were associated with travelers who brought measles back from Israel, where a large outbreak was occurring. There were 375 measles to the U.S. in 2018. In 2019, 1,282 cases of measles were confirmed in 31 states in the U.S.

How Do We Compare With the U.S.?

Measles prevalence was virtually non-existent in both Utah and the U.S. during 2006-2010. After the 2011 measles outbreak, the case count in Utah decreased to one case in 2012 and zero cases in 2013. In December of 2014, Utah experienced an outbreak of measles in which three cases were identified and associated with a national outbreak out of Orange County, California. Due to the 2014 measles outbreak, the rate of measles in Utah was 0.10 cases per 100,000 persons, compared to the U.S. rate of 0.21 cases per 100,000 persons in 2014; the U.S. rate reflects the impact of other outbreaks in the U.S. during that time. In February 2017, Utah experienced another outbreak of measles in which three cases were identified. The index case was appropriately immunized for age but had traveled to an area where measles is endemic without receiving a second MMR dose as recommended by the CDC. Upon returning to Utah, the index case had extensive contacts during the infectious period related to church gatherings, family events, and multiple medical visits. Two unvaccinated contacts of the index case were subsequently confirmed as measles cases. Measles cases in Utah decreased from 0.10 cases per 100,000 population in 2014 to 0.0 cases per 100,000 in 2016. As a result of an outbreak in 2017, the rate of measles in Utah was 0.10 per 100,000 population in 2017. In 2018 and 2019, the rate of measles in Utah was 0.0 per 100,000 population. There was a decrease in measles cases reported in the U.S. from 667 (0.21 cases per 100,000 population) in 2014 to 120 (0.04 cases per 100,000 population) in 2017. In 2018, there were 375 cases reported (0.11 per 100,000 population) in the U.S. In 2019, there were 1,282 cases of measles (0.39 per 100,000 population) in the U.S.

What Is Being Done?

Travelers to foreign endemic countries frequently import the highly contagious measles virus into the U.S. Each imported measles case could start an outbreak, especially if under-vaccinated groups are exposed. Surveillance and prompt investigation of cases and contacts are critical to halt the spread of disease. Surveillance data are used to characterize persons, groups, or areas in which additional efforts are required to reduce disease incidence. Childhood immunization is the most effective weapon against measles infection. UDOH Immunization Program staff work with parents, physicians, and local health departments to provide immunization histories for all children under age two and remind parents when vaccinations are due. Since 1996, the Utah immunization rate has improved. Staff from the UDOH Bureau of Epidemiology conduct ongoing statewide surveillance of measles cases. Per Communicable Disease Rule R386-702-3, health care providers and laboratories are required to report suspected cases of measles immediately by telephone to the Bureau of Epidemiology or the local health department. When measles is reported the Bureau of Epidemiology assists local health departments with the investigation of cases and implementation of control measures to prevent further cases. Control measures were implemented by public health during the 2014 and 2017 measles outbreaks, limiting the spread of the disease. The control methods used for these responses resulted in the post-exposure treatment of over 200 persons, over 800 MMR containing vaccines administered by the local health departments, and the voluntary quarantine of 443 susceptible community members. Public health officials continue to conduct ongoing surveillance for measles cases in Utah.

Available Services

Public health clinics and private provider offices offer vaccines to adults, adolescents, and children in their communities. For general information about immunizations please call the State Immunization Program at 1-800-275-0659 or visit us at our web site: [https://www.immunize.utah.gov]

Health Status Outcomes

Complications from measles occur most frequently in children under 5 years of age and adults over 20 years of age. In very young or malnourished patients, blindness can occur.
