El Paso, Texas, is experiencing its first measles outbreak in more than two decades, reports ABC affiliate KVIA.
In the past two weeks, El Paso health officials have confirmed five measles cases affecting two adults and three toddlers.
While the city has high immunization rates, officials are still making a major push to vaccinate kids before the new school year starts, according to KFOX 14 News.
"After going 25 years in El Paso without any cases, having one is one too many," Robert Resendes, the city's public heath director, told KVIA.
Nationwide, the CDC has confirmed 1,148 measles cases this year as of July 18 — the largest number of cases since 1992.
