CDC – Measles Cases and Outbreaks (as of 4-27-15)
2015 measles cases
 From January 1 to April 24, 2015, 166 people from 19 states in the U.S. and the District of
Columbia have been reported as having measles [AZ (7), CA (103), CO (1), DC (2), DE (1), FL (5),
GA (1), IL (15), MI (1), MN (1), NE (2), NJ (1), NY (3), NV (9), OK (1), PA (1), SD (2), TX (1), UT (2),
WA (7)]*. Most of the cases [117 (70%)] are considered to be part of a multi-state outbreak
linked to an amusement park in California.
o Most of these people were unvaccinated (about 5 out of 10) or did not know whether they
were vaccinated (about 4 out of 10). A minority of them were vaccinated (about 1 out of 10).
o Reasons for not receiving measles vaccine include philosophical or religious objections,
ineligible, missed opportunities for vaccination, and other.
o Cases have ranged from 6 weeks to 70 years.
o Some of them have been hospitalized.
o Of the 166 measles cases, 160 (96%) were import-associated.
o Fourteen of these people brought measles into the U.S. after getting infected in other
countries (Indonesia, Singapore/Indonesia, India, Dubai/India, Qatar, Azerbaijan, Pakistan,

o
Kyrgyzstan, Germany, and China respectively). Some of them spread measles to other people
in the U.S.
Measles genotypes identified to date include B3, D4, D8, D9, and H1.
*Preliminary data reported to CDC’s National Center for Immunization and Respiratory Diseases, updated weekly
on Mondays.

U.S. multi-state measles outbreak, December 2014—April 2015

The U.S. experienced a multi-state outbreak of measles linked to an amusement park in California.
o From December 28, 2014 to April 24, 2015, 147* people from 7 states in the U.S. [AZ (7), CA
(131), CO (1), NE (2), OR (1), UT (3), WA (2)] have been reported to CDC as having measles and
are considered to be part of this outbreak. Additional cases linked to this outbreak have been
reported in Mexico and Canada.
o The source of the outbreak has not been identified. However, it likely started from one or
more travelers who got measles overseas then visited the amusement park while infectious
and spread it to others.
o Analysis by CDC scientists shows that the measles virus type in this outbreak (B3) is identical
to the virus type that caused the large measles outbreak in the Philippines in 2014. This virus
type has also been identified within the past 6 months in 14 other countries. Additionally, at
least six other states in the U.S. have had measles cases with B3 virus type, not associated
with the current outbreak.
*Outbreak includes 30 cases reported in 2014
Measles Vaccination Recommendations

The best protection against measles is MMR vaccine. MMR vaccine provides long-lasting protection
against all strains of measles. Make sure you’re up to date on MMR and other vaccinations.
o Children should receive two doses of MMR vaccine–the first dose at 12 through 15 months of
age and the second dose 4 through 6 years of age. Giving the second dose of the vaccine earlier
is allowed at any time as long as it is at least 28 days after the first dose.
o Unless they have evidence of measles immunity, college and other students, health care
personnel, and international travelers need 2 appropriately spaced doses and other adults need
1 dose. Ask your health care provider if you have questions about whether you need MMR
vaccine.
o People who received two doses of MMR vaccine as children according to the U.S. vaccination
schedule do not ever need a booster dose.
The Recommended Immunization Schedules for Persons Aged 0 Through 18 Years – United States, 2015,
and the Recommended Adult Immunization Schedule – United States, 2015, have been published and
are available at the following link:

Guidance for Clinicians

Healthcare providers should be vigilant about measles—
o Ensure all patients are up to date on measles-mumps-rubella (MMR) vaccine.
o Consider measles in patients presenting with febrile rash illness and clinically compatible
measles symptoms (cough, coryza, and conjunctivitis), and ask patients about recent travel
internationally or to domestic venues frequented by international travelers, as well as a history
of measles exposures in their communities.
o Promptly isolate patients with suspected measles to avoid disease transmission and
immediately report the suspect measles case to the local health department and MDPH at 617983-6800. Cases diagnosed in Boston should be reported to the Boston Public Health
Commission at 617-534-5611.
o Obtain specimens for testing from patients with suspected measles, including viral specimens
(NP swab in viral transport media) for genotyping, which can help determine the source of the
virus.
o Contact the Massachusetts Department of Public Health with questions about submitting
specimens for testing at 617-983-6800.

During a measles outbreak health officials may recommend giving a dose of MMR vaccine in excess
of, or earlier than, what is recommended in the U.S. vaccination schedule, as an outbreak-control
measure:
o If many cases are occurring among infants younger than 12 months of age with an ongoing risk
for exposure (e.g., an outbreak in a childcare center), health officials may recommend giving
measles vaccine to infants as young as 6 months of age.
 Note that children vaccinated before their first birthday should be revaccinated when they
are 12 through 15 months old, and again when they are 4 through 6 years of age.
o If many cases are occurring among preschool-aged children, health officials might recommend
that a second dose of MMR vaccine be given to children ages 1 through 4 years.
o If many cases are occurring among adults with community-wide transmission, health officials
might recommend that adults who only have documentation of 1 dose of MMR vaccine be given
a second.
o State health departments have authority to provide revised vaccine recommendations during
measles outbreaks.

Measles Vaccination Recommendations for those who travel internationally
People traveling outside of the United States are at increased risk of exposure to measles and should
have evidence of measles immunity. This disease is quite common in many countries throughout the
world. The CDC recommends that travelers who are not immune to measles receive two doses of the
MMR vaccine for their own protection and to prevent importation of the measles virus into the United
States.
Before any international travel, infants 6 months through 11 months of age should have at least one
dose of MMR vaccine. Children 12 months of age or older should have two doses separated by at least
28 days. Adults should review their vaccination records to ensure they're up to date. The links below
provide valuable information to help travelers protect themselves and others from measles.

CDC Travelers’ Health
CDC Travel Advisory on Measles
The CDC “Health Information for International Travel” (commonly called the Yellow Book) serves as
a reference for those who advise international travelers about health risks.
Travelers’ Health has specific guidance for audiences that may be at higher risk for measles, such as
humanitarian aid workers, long-term travelers, and VFR travelers.

Massachusetts School Immunization Requirements for School Year 2014-2015*
The Massachusetts School Immunization Requirements for School 2014-2015 can be found at the
following link: http://www.mass.gov/eohhs/docs/dph/cdc/immunization/guidelines-ma-schoolrequirements.pdf
Massachusetts Immunization Exemptions
Massachusetts Immunization Exemptions and Vaccine Preventable Disease Exclusion During Disease
Outbreaks can be found at the following link:
http://www.mass.gov/eohhs/docs/dph/cdc/immunization/guidelines-vaccine-exclusions-school.pdf
Definition of Allowable Exemptions
There are two situations in which children who are not appropriately immunized may be admitted to
school:
1) A medical exemption is allowed if a physician submits documentation attesting that an
immunization is medically contraindicated; and
2) A religious exemption is allowed if a parent or guardian submits a written statement that
immunizations conflict with their sincere religious beliefs.
Philosophical exemptions are not allowed by law in Massachusetts, even if signed by a physician. Only
medical and religious exemptions are acceptable. These exemptions must be kept in the students’ files
at school (105 CMR 220.000 and M.G.L. c.76, ss. 15, 15C and 15D).
Exclusion During Disease Outbreaks
2015 Measles Update (as of 4-27-15)
Page 5
In situations when one or more cases of a vaccine-preventable or any other communicable disease are
present in a school, all susceptibles, including those with medical or religious exemptions, are subject
to exclusion as described in the Reportable Diseases and Isolation and Quarantine Requirements (105
CMR 300.000). The reporting and control of diseases identified as posing a risk to the public health is
prescribed by state regulation and law. The Isolation and Quarantine Requirements establish isolation
andquarantine requirements for cases of certain diseases and their contacts in certain high-risk
situations,including the school setting. The following table outlines several of the more common
childhood vaccine-preventable diseases identified in the requirements that may occur in schools and the
corresponding exclusion requirements.
Exclusion Guidelines for Select Vaccine-Preventable Diseases in a School Setting
Disease: Measles
Case and Symptomatic Contacts
Exclude student/staff through 4 days after onset of rash. (Count the day of rash onset as day zero.)
Asymptomatic Contacts
If one case: exclude susceptibles1 from work or classes from the 5th through the 21st day after their
exposure.
If multiple cases or continuous (two or more days) exposure: exclude susceptibles1
through the 21st day after rash onset in the last case.
These restrictions remain even if the contact received immune globulin (IG).
Definition of Susceptibles:
1 Measles - Susceptibles include all those born in or after 1957 without: 1) written documentation of 2
doses of measles-containing vaccine; or 2) laboratory evidence of immunity or laboratory confirmation
of disease. In an outbreak setting, all those with 0 or 1 dose may avoid exclusion if they promptly
receive a dose. Those born in the United States before 1957 are considered immune; however, this
should not be considered evidence of immunity for health sciences students and health care workers.*
*Health care workers and health sciences students should have 2 doses of MMR and varicella,
laboratory evidence of immunity or laboratory confirmation of disease.
