VANCOUVER, Wash. – Clark County Health Officials have confirmed another case of the measles, but the number of confirmed cases remains at 53 after another previously confirmed case was proven to be a benign vaccine rash.
The county says there are also two new suspected cases.
The confirmed case that was proven to be a vaccine rash was in a child between 1 and 10 years old. The unimmunized child had received one does of the measles-mumps-rubella vaccine and developed a rash. Medical officials say this happens to about 5 percent of previously unvaccinated people.
Initial lab results in this case tested positive for measles. During testing at a specialized, out-of-state laboratory, doctors determined the child was experiencing a vaccine rash. People who experience mild vaccine-associated rashes cannot transmit it to other people.
Since the child has been removed from the list of confirmed cases, Clark County has also removed four exposure locations: St. Paul Christian Daycare (Jan. 23), The Vancouver Clinic Salmon Creek (Jan. 23), Vancouver Women, Infant and Children office (Jan. 23) and Tower Mall public areas (Jan. 23).
Currently, there are 38 confirmed cases in children between the ages of 1 and 10. There are 13 cases in children between the ages of 11 and 18. There is one case in an adult between ages 19 and 29 and one case in an adult between ages 30 and 39.
Officials say 47 of the confirmed cases occurred in people who were not immunized. Five cases have their immunization status unverified and one person had one dose of the MMR vaccine.
