Health officials across Texas remain on high alert after a deadly measles outbreak in the South Plains region.

The state health department said one child has died and 146 people have been diagnosed with the illness. A majority of those infected are unvaccinated children.

Dr. Donna Persaud, medical director for homeless outreach medical services at Parkland Hospital in Dallas, said they have seen a steady decline in vaccinations in recent years.

"The vaccine rate amongst kindergartners has decreased throughout the 2000s, and part of that has been the inclusion and addition of nonmedical exemptions," Persaud explained. "They've fallen to rates where outbreaks are likely."

She pointed out the vaccine rate among kindergartners is less than 95 percent. Among the victims, 70 are between the ages of 5 and 17.

Most of the current patients live within a Mennonite community but cases are also being diagnosed in other parts of the state. Measles is an airborne illness and highly contagious. Persaud emphasized the medical community is concerned.

"All the clinics and health care entities, we're about to convene a special committee," Persaud noted. "We're looking at putting up signs, posters and looking at the CDC recommendations. These are now the questions: What about adults? Should I get another vaccine? Should I get a booster?"

Persaud stressed if you have had the measles, if you were born in or before 1957, or if you have proof of receiving two vaccines, you are immune. She added some measles vaccines in the '60s were not effective, and anyone born during that decade should check with their doctor.
