The Pima County Health Department is advising area hospitals and medical providers that the required two incubation period from the last confirmed measles case has passed effectively ending the measles outbreak which began in mid-February. While the initial case count for Pima County was 22, upon retrospective analysis by the Centers for Disease Control, the Arizona Department of Health Services and the Health Department, the final case count was 13 laboratory confirmed and 4 probable measles cases.

The outbreak started with a visit to the Old Pueblo by a traveler from Switzerland and ended five months later with thousands of residents receiving MMR (measles, mumps, rubella) vaccinations, hundreds of case investigations conducted by Health Department staff, and a public health emergency declaration by Pima County.

The following information is provided to give a brief overview of the activities conducted during the outbreak:

"While I am comfortable in saying Pima County's measles outbreak is over, it is important to stress the need for all health care providers to remain vigilant with regard to measles," stated Michelle McDonald, M.D., Chief Medical Officer for the Pima County Health Department. "With confirmed cases still being diagnosed all over the world, we cannot afford to let our guard down concerning this highly contagious disease."
