CDC publishes "Measles Outbreak—California, December 2014–February 2015" in a MMWR Early Release
On February 13, CDC published Measles Outbreak—California, December 2014–February 2015 in a MMWR Early Release. As of February 11, a total of 125 measles cases had been confirmed among U.S. residents in an ongoing measles outbreak linked to two Disney theme parks in Orange County, California. The entire text of the article is reprinted below (acknowledgements, references, and figure not included).
On January 5, 2015, the California Department of Public Health (CDPH) was notified about a suspected measles case. The patient was a hospitalized, unvaccinated child, aged 11 years, with rash onset on December 28. The only notable travel history during the exposure period was a visit to one of two adjacent Disney theme parks located in Orange County, California. On the same day, CDPH received reports of four additional suspected measles cases in California residents and two in Utah residents, all of whom reported visiting one or both Disney theme parks during December 17–20. By January 7, seven California measles cases had been confirmed, and CDPH issued a press release and an Epidemic Information Exchange (Epi-X) notification to other states regarding this outbreak. Measles transmission is ongoing.
As of February 11, a total of 125 measles cases with rash occurring during December 28, 2014–February 8, 2015, had been confirmed in U.S. residents connected with this outbreak. Of these, 110 patients were California residents. Thirty-nine (35%) of the California patients visited one or both of the two Disney theme parks during December 17–20, where they are thought to have been exposed to measles, 37 have an unknown exposure source (34%), and 34 (31%) are secondary cases. Among the 34 secondary cases, 26 were household or close contacts, and eight were exposed in a community setting. Five (5%) of the California patients reported being in one or both of the two Disney theme parks during their exposure period outside of December 17–20, but their source of infection is unknown. In addition, 15 cases linked to the two Disney theme parks have been reported in seven other states: Arizona (seven), Colorado (one), Nebraska (one), Oregon (one), Utah (three), and Washington (two), as well as linked cases reported in two neighboring countries, Mexico (one) and Canada (10).
Among the 110 California patients, 49 (45%) were unvaccinated; five (5%) had 1 dose of measles-containing vaccine, seven (6%) had 2 doses, one (1%) had 3 doses, 47 (43%) had unknown or undocumented vaccination status, and one (1%) had immunoglobulin G seropositivity documented, which indicates prior vaccination or measles infection at an undetermined time. Twelve of the unvaccinated patients were infants too young to be vaccinated. Among the 37 remaining vaccine-eligible patients, 28 (67%) were intentionally unvaccinated because of personal beliefs, and one was on an alternative plan for vaccination. Among the 28 intentionally unvaccinated patients, 18 were children (aged <18 years), and 10 were adults. Patients range in age from 6 weeks to 70 years; the median age is 22 years. Among the 84 patients with known hospitalization status, 17 (20%) were hospitalized.
The source of the initial Disney theme park exposure has not been identified. Specimens from 30 California patients were genotyped; all were measles genotype B3, which has caused a large outbreak recently in the Philippines, but has also been detected in at least 14 countries and at least six U.S. states in the last 6 months.
Annual attendance at Disney theme parks in California is estimated at 24 million, including many international visitors from countries where measles is endemic. The December holiday season coincides with the exposure period of interest. Since 2011, six confirmed measles cases have been reported to CDPH in persons whose notable exposure was to large theme parks that attract international tourists. International travel to countries where measles is endemic is a well-known risk factor for measles, and measles importations continue to occur in the United States; the number of measles cases reported to CDC is updated weekly at http://www.cdc.gov/measles/cases-outbreaks.html. However, U.S. residents also can be exposed to measles in the United States at venues with large numbers of international visitors, such as other tourist attractions and airports. This outbreak illustrates the continued importance of ensuring high measles vaccination coverage in the United States.
Experts provide valuable editorials and interviews during measles outbreak
As the measles outbreak continues in the United States, the media have been busy providing information (and some misinformation) about measles and vaccination rates and exemption policies. Fortunately, many vaccine advocates have answered the media's call and dedicated valuable time to answering questions and providing basic science-based information and opinions. The following is just a tiny sampling.
Voices for Vaccines provides resources for anyone who wants to promote vaccination
Voices for Vaccines has developed resources for parents and others looking to make a difference in countering anti-vaccine forces, especially during this time of intense interest in the subject due to the multi-state measles outbreak.
Organizations offer free educational materials about measles for healthcare professionals and patients
Please refer to the following information and resources as we all work together to help stop the spread of measles during this multi-state outbreak.
MEASLES RESOURCES FOR HEALTHCARE PROVIDERS
IAC Spotlight! Ten healthcare organizations join IAC's Influenza Vaccination Honor Roll for mandatory healthcare worker vaccination
IAC urges qualifying healthcare organizations to apply for its Influenza Vaccination Honor Roll. The honor roll recognizes hospitals, medical practices, professional organizations, health departments, and government entities that have taken a stand for patient safety by implementing mandatory influenza vaccination policies for healthcare personnel. More than 500 organizations are now enrolled.
Since January 20, when IAC Express last reported on the Influenza Vaccination Honor Roll, 10 healthcare organizations have been enrolled.
Newly added healthcare organizations, hospitals, and government agencies
Deadline for National Adult and Influenza Immunization Summit awards extended to March 1
The National Adult and Influenza Immunization Summit (NAIIS) has extended the deadline to submit nominations for the 2015 NAIIS Immunization Excellence Awards to March 1. The 2015 awards recognize individuals and organizations that made extraordinary contributions towards improving vaccination rates within their communities during 2014. The awards focus on individuals and organizations that exemplify the meaning of the “immunization neighborhood” (collaboration, coordination, and communication among immunization stakeholders dedicated to meeting the immunization needs of the patient and protecting the community from vaccine-preventable diseases). The "Adult Immunization Publication Award" has been added this year, making a total of six categories. Unless specifically indicated in the award description, the immunization activities should be broader than influenza activity. A National Winner and possibly an Honorable Mention recipient will be selected for each award category.

National Meningitis Association offers two PSAs that encourage parents to vaccinate their children against meningococcal disease
The National Meningitis Association (NMA) recently developed two new public service announcements (PSAs) that are available for other groups to share via their websites and social media outlets. Both PSAs follow the stories of NMA advocates who lost their children to meningococcal disease. There are two versions:
Influenza is spreading and serious; please keep vaccinating your patients
According to CDC, U.S. influenza activity is high across most of the country with flu illnesses, hospitalizations, and deaths elevated. Flu season will probably continue for several weeks. While the influenza vaccine may not work as well as usual against some H3N2 viruses, vaccination can still offer protection for some people, reduce hospitalizations and deaths, and will protect against other influenza viruses. Influenza vaccination is recommended for everyone six months of age and older. If you don't provide influenza vaccination in your clinic, please recommend vaccination to your patients and refer them to a clinic or pharmacy that provides vaccines or to the HealthMap Vaccine Finder to locate sites near their workplaces or homes that offer influenza vaccination services. Influenza antiviral drugs can treat influenza illness. CDC has issued guidance for clinicians on the use of antiviral treatment for the 2014–15 flu season. Early antiviral treatment works best.

ASK THE EXPERTS
Question of the Week
How does being born before 1957 confer immunity to measles?
People born before 1957 lived through several years of epidemic measles before the first measles vaccine was licensed in 1963. As a result, these people are very likely to have had measles disease. Surveys suggest that 95% to 98% of those born before 1957 are immune to measles (see www.cdc.gov/vaccines/vpd-vac/measles/faqs-dis-vac-risks.htm). Persons born before 1957 can be presumed to be immune. However, if serologic testing indicates that the person is not immune, at least 1 dose of MMR should be administered. Additional information is available at www.cdc.gov/mmwr/pdf/rr/rr6204.pdf.
