WILLIAMSON COUNTY, Texas (KXAN) -- A second case of measles was confirmed in Williamson County on Tuesday.
The case involved an unvaccinated adult resident from Leander, the Williamson County and Cities Health District (WCCHD) said in a press release.
According to officials, the individual is no longer in their infectious period and was not present in the Williamson County area while they were contagious.
WCCHD, the Texas Department of State Health Services (DSHS), along with local health authorities said it will directly notify individuals who may have been exposed, the release added.
All three agencies are actively working together to assess any potential contacts as part of the ongoing public health investigation.
"Vaccination is one of the most powerful tools we have to prevent the spread of measles and protect our community, " said Dr. Amanda Norwood, WCCHD Medical Director. Norwood added "two doses of the MMR vaccine offer safe, strong, long-lasting protection."
On May 22, KXAN reported Williamson County's first measles case was a school-age child from Leander. Liberty Hill Independent School District had sent a letter to parents informing them that the case involved a "school-aged child who attended Bar W Elementary School," KXAN reported.
Other counties in Texas have reported cases, including Hays County. According to the Texas Department of State Health Services, two cases have been reported in Travis County.
More than 720 cases have been confirmed, with cases primarily in the outbreak area in West Texas since late January, DSHS said.
If you think you've been exposed, or if you begin to show symptoms, WCCHD advised to contact your healthcare provider before going to a clinic or hospital, to help reduce the risk of exposing others.
