Logical! Unlike yourself.
Measles has been virtually wiped out. An outbreak is a rarity due to the vaccine.

Investigation and Results
After receiving notification of the first case on April 10, MDH and the Hennepin County Human Services and Public Health Department began an investigation. The Council of State and Territorial Epidemiologists and CDC case definition* was used to identify confirmed cases of measles in Minnesota (
1). A health alert was issued April 12, which notified health care providers of the two measles cases in Hennepin County and provided recommendations concerning laboratory testing for measles and strategies to minimize transmission in health care settings. Emphasis was placed on recommendations for all children aged ≥12 months to receive a first dose of MMR. Providers identified patients with suspected measles based on clinical findings and reported suspected cases to MDH. Testing with rRT-PCR was performed at MDH on nasopharyngeal or throat swabs and urine specimens. Among persons testing positive by rRT-PCR who had received vaccine ≤21 days before the test, genotyping was performed to distinguish wild-type measles virus (genotype B3 virus) from the vaccine virus (genotype A virus). Patients (or their parents or guardians) with confirmed measles were interviewed by local public health officials to confirm symptoms, onset date, and exposure history for the 21 days before rash onset and identify contacts during their infectious period (4 days before through 4 days after rash onset). Contacts were defined as persons who had any contact with patients during their infectious period.
Among the 65 confirmed cases, the median patient age was 21 months (range = 3 months–49 years). Patients were residents of Hennepin, Ramsey, LeSueur, and Crow Wing counties. During April 10–May 31, confirmed measles patients were identified in five schools, 12 child care centers, three health care facilities, and numerous households; an estimated 8,250 persons were potentially exposed to measles in these settings.
Rash onset dates ranged from March 30–May 27, 2017. Sixty-two (95%) cases were identified in unvaccinated persons, including 50 (77%) in children aged ≥12 months (i.e., age-eligible for MMR vaccination). U.S.-born children of Somali descent (Somali children) accounted for 55 (85%) of the cases. Among the three patients with a history of measles vaccination, all had received 2 MMR doses before illness onset. As of May 31, 20 (31%) patients had been hospitalized, primarily for treatment of dehydration or pneumonia; no deaths had been reported"
