Measles might be present in Clark County.

Clark County Public Health is investigating a potential case of measles in a child. The child’s gender and exact age was not disclosed, but Dr. Rachel Wood, a health officer for Lewis and Thurston counties, said the child has displayed measles’ symptoms such as a fever and rash.

The child, who is no older than 10, is up to date on their immunizations, and is believed to have been exposed to an individual from Multnomah County, Ore., who was later confirmed to have measles.

Measles can linger in the air for a couple hours, even after the person with the virus has left.

People who visited three businesses in late June may have been exposed to measles, according to a press release from Clark County Public Health: J.C. Penney, 19005 S.E. Mill Plain Blvd., Vancouver (from 2 to 5 p.m. June 27); Ross Dress for Less, 4708 N.E. Thurston Way, Vancouver (noon to 3 p.m. June 28); Svitoch, 4804 N.E. Thurston Way, Vancouver (noon to 3 p.m. June 28).

“If people were in those locations during those dates and times and think they’ve been exposed to measles or have symptoms, they need to call their health care providers,” said Wood, who was filling in for Clark County Health Officer Dr. Alan Melnick.
