Public Health is investigating a measles infection in a Pierce County resident who spent time in King County druing the infectious period, before being diagnosed with measles. The source of the infection for this man is unknown but was presumably acquired in Pierce County or King County, as the patient reports no travel outside the state or country during his exposure period. The patient’s onset of rash was May 10, 2019. Secondary cases resulting from this case would be expected to occur between May 13 and June 1, 2019.
Measles cases continue to occur in the U.S. with over 839 individual cases of measles confirmed in 23 states this year (as of 5/10/19) and 29 cases of measles so far this year (as of 5/6/19) among residents of British Columbia, Canada. Currently the Centers for Disease Control and Prevention has travel notices posted for the following five countries due to ongoing measles outbreaks: Israel, Ukraine, Japan, Brazil and Philippines.
