This is the first case of measles reported in Williamson County this year.
AUSTIN, Texas — Williamson County health officials have confirmed the county’s first measles case of 2025.
A school-aged child in Leander has tested positive for measles, Williamson County officials announced Thursday. According to the Williamson County and Cities Health District, the child is currently recovering at home in isolation.
Officials say they don’t know the child’s vaccination status because their family has chosen to not share those details. Because the child’s vaccination status is unclear, health officials say it limits their ability to fully assess potential exposure risks or the source of the infection.
Officials say the child has been contagious since May 15 and may continue to be contagious through May 24. During this period, officials say there is a potential for exposure to others in the community.
“We respect the privacy of families while emphasizing that timely communication is critical protecting the health of our Williamson County community,” Dr. Amanda Norwood, the Medical Director and Health Authority for the Williamson County and Cities Health District, said in a news release Thursday. “We strongly urge our neighbors in Williamson County to stay alert and take extra precautions at this time. It’s critical to recognize the early signs of measles and act quickly to protect your family and those around you.”
As of May 20, there have been 722 confirmed cases of measles in Texas, largely stemming from an outbreak that began in West Texas earlier this year.
