YISD Investigation into Hanks Tuberculosis Exposure Yields Two Positive Test Results

On Wednesday afternoon, the Department of Public Health (DPH) announced two individuals have tested positive for Tuberculosis (TB) infection in the recent investigation involving Hanks High School.

The department identified 140 individuals who may have been exposed to a person at the school who was diagnosed with active TB disease and a 138 individuals have been screened. Tests revealed two positive results.

The following is a chart describing the current investigation standings.

Persons Potentially Exposed 140
Tested To-Date 138
Test Rate 99%
Results Known 136
Number of Positive Results 2
Positivity Rate 1.5%

Public Health officials estimate a positivity rate for El Paso between 5% and 10%, and the actual rate of 1.5% is well below what is expected.

Those tested by DPH have been notified of their results and the two patients who tested positive for TB infection will be evaluated by a nurse specializing in TB. They will also receive X-rays to ensure the disease has not developed in their lungs. Those who tested negative for TB will be retested within the next 8 to 10 weeks as a precaution.

“While we wish there were no TB in El Paso, the fact is that the disease is part of our everyday life,” said Robert Resendes, Public Health Director. “We are pleased with this low number, and hope to see similar results in February when we retest these individuals.”

Last year, 43 cases of active TB were identified and treated in the greater El Paso region with 38 in 2015 and 44 in 2014. Every year, the department identifies and treats approximately 250 latent cases of the disease.

Dept. of Health: Tuberculosis Testing Yields Positive Results at Local Adult Day Care Center

The City of El Paso Department of Public Health (DPH) has received preliminary results of 199 individuals tested during an investigation of a possible Tuberculosis (TB) exposure at a local senior day care center.

A total of 199 people were tested using blood samples, with 65 of those tests coming back positive for TB infection.

None of the people tested showed signs or reported symptoms of having active TB and further testing will be conducted as part of the investigation process to determine their status.

“While this is a relatively high rate of positivity, we must also consider, among other factors, that any elderly population will likely have higher positivity rates due to prior exposure so a positive test could be unrelated to this particular exposure event,” said Robert Resendes, Public Health Director. “What we want the attendees and the community at large to know is that there is a systematic process in place to ensure everyone’s safety.”

The next step in the investigation will be providing test results to those who were tested at the day care facility. Those who tested positive will then require further workup including physical evaluations by DPH TB nurses as well as chest x-rays. For those with no insurance or means to pay, the Department will arrange for them to obtain their chest x-ray at no cost to them. It is expected that completion of the x-ray phase of the investigation will take about two weeks.


Tuberculosis is caused by a bacterium called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. Not everyone infected with TB bacteria becomes sick. As a result, two TB-related conditions exist: latent TB infection (LTBI) and TB disease.

If not treated properly, TB disease can be fatal. TB bacteria are spread through the air from one person to another. The TB bacteria are put into the air when a person with TB disease of the lungs or throat coughs, speaks, or sings. People nearby may breathe in these bacteria and become infected.

TB is NOT spread by

  • shaking someone’s hand
  • sharing food or drink
  • sharing toothbrushes
  • kissing
  • touching bed linens or toilet seats

When a person breathes in TB bacteria, the bacteria can settle in the lungs and begin to grow. From there, it can move through the blood to other parts of the body, such as the kidney, spine, and brain. TB disease in the lungs or throat can be infectious. This means that the bacteria can be spread to other people. TB in other parts of the body, such as the kidney or spine, is usually not infectious.

People with TB disease are most likely to spread it to people they spend time with every day. This includes family members, friends, and coworkers or schoolmates.

Three more test positive for TB at Horizon City school; Returning to class is ‘safe’

On Thursday morning, the City of El Paso’s Department of Public Health announced that they have identified three more people who have tested positive for Tuberculosis at Frank Macias Elementary in Horizon City.

“We want to make sure that parents, students, and staff realize that returning to school next week is safe, and that the Department of Public Health encourages everyone involved to get back to the important process of learning,” said Robert Resendes, Public Health Director.

The new positive test bring the total of those with TB to five at the elementary school.

According to officials, the re-testing took place last week and  “is a standard procedure and is conducted eight to ten weeks after the last possible exposure to an active case of TB.”  Department officials added that, “it is not unusual to find new positives during re-testing because enough time has passed for the bacteria to incubate and for the body to produce the necessary reaction to create a positive test result.”

Further testing for those who are negative a second time will not be necessary based on this investigation.

Officials with the department say, those who tested positive during the re-test will go through the same procedures as those who tested positive earlier on. They add, “After chest x-rays and/or sputum samples are reviewed, they will be offered medication to prevent the disease from becoming active if it is indicated.”

Results from those tests are not expected until late next week.
