Two Texas universities and their surrounding communities have issued warnings about potential exposure to measles after giving campus tours to at least one person who tested positive for the virus. Experts have been tracking the measles outbreak in Gaines County since late January.

A warning has been issued for three Texas cities after someone with measles visited them while contagious. The Texas Department of State Health Services (DHSH) shared the warning on Monday "so unvaccinated people may monitor themselves for symptoms and seek testing if symptoms occur.

The Hays County Health Department alerted residents about possible exposure to a person who tested positive for measles.

Measles exposures in Central Texas have been linked to visitors from Gaines County in West Texas, where a measles outbreak is reaching close to triple digits.

State health officials confirm an individual with the disease was in multiple high-traffic areas in and around San Antonio, New Braunfels and San Marcos during the Valentine's Day weekend.

The number of measles cases linked to an outbreak in West Texas has grown to 58, according to the Texas Department of State Health Services.
