If You Know of a Baby Treated in an El Paso, Texas, Hospital, You Should Click Here

EL PASO, Texas (TheBlaze/AP) -- Five babies have tested positive for tuberculosis in West Texas after a nurse assistant at an El Paso hospital exposed hundreds of infants to the disease between September 2013 and last month.

The El Paso Department of Public Health says in a statement that none of the children have active TB, the deadly and contagious form of the illness. All five will be treated.

The department also says it is expanding the list of children who may have been exposed by 96, bringing the total to about 850.

The facility, Providence Memorial Hospital, welcomed Centers for Disease Control and Prevention officials on Monday who are dealing with the issue, according to KFOX-TV.

Hospital officials have said they "should have done more" when the employee's symptoms were revealed during her annual screening in July. She was tested in August and put on leave.

Further testing of all the babies is ongoing.

“If you receive a letter, please contact 211 and make an appointment, it’s very important," El Paso Mayor Oscar Leeser told the news station.
