Five babies in El Paso, Texas have tested positive for tuberculosis.

Providence Memorial Hospital has identified more than 850 infants and 43 health care workers who were potentially exposed between September 2013 and August 2014. The cases emerged after a nurse came to work with a case of TB.

The nurse worked with infants in the nursery and in the postpartum unit at the hospital, according to reports.

Health officials said the five babies who tested positive do not have active cases of TB. Four received the Bacillus Calmette-Guerin vaccine for TB that may be generating false positive test results, they said.

Still, all five will be given TB treatment.

Patient exposed to Ebola held in isolation

Also in Texas, the Texas Health Presbyterian Hospital of Dallas has a patient in isolation because of potential exposure to the Ebola virus.

Dallas County's Health and Human Services director says the patient had been in an area where the Ebola virus exists. They would not say where the patient traveled.

The hospital said it is following all Centers for Disease Control and Prevention and Texas Department of Health recommendations. The CDC was anticipating preliminary test results Tuesday.

Aspirin may cut prostate cancer risk

New research on aspirin suggests it could lower some men's risk of developing prostate cancer.

A study looked at more than 6,300 men, half of whom never used aspirin or other anti-inflammatory medication. Researchers found that anti-inflammatory use reduced the overall risk for prostate cancer by 13 percent and risk of high-grade prostate cancer by 17 percent.

Investigators say more research is needed to better understand the cause and effect relationship. But they believe that aspirin's ability to reduce inflammation may have something to do with it.

Inflammation in the body has been shown to be a factor in the development of some cancers and heart issues. Some doctors have already been recommending a small daily dose of aspirin to reduce the risk of a heart attack.
