The U.S. Centers for Disease Control and Prevention (CDC) is looking into a possible breach of protocol, which may be the reason behind the infection of a second Ebola patient in Dallas, reports revealed Sunday.

In a press conference held on the same day, the agency confirmed another Ebola infection in Texas. The CDC explained that they are currently investigating a possible breach in protocol while Thomas Duncan, the first U.S. Ebola patient, was being treated.

According to CDC director Thomas Frieden, the second Ebola patient who tested positive of Ebola, had been a medical worker helping in the treatment of Duncan at the Texas Health Presbyterian Hospital in Dallas.

Frieden explained that the infected worker may have not followed the proper procedure intended for the removal of contaminated protective gear, citing that "enhanced training" may be needed for the incident to not happen again.

"We will undertake a complete investigation of how this may have occurred. That's so important, so we can understand it better, and intervene to prevent this from happening in the future," he declared emphasizing that the set up Ebola "protocols work."

After interviewing the patient, who had not been named as of the moment, the CDC explained that she was not able to identify when the breach of protocol occurred.

Reports indicate that the second Ebola patient experienced symptoms, such as a low fever, on Friday evening when she drove herself to the same hospital she worked for.

Within one and a half hour after her arrival at the medical facility, she was immediately put into isolation.

Come Saturday evening, her preliminary Ebola test returned positive.

Reports revealed that the infected nurse had been self-monitoring-taking her temperature two times a day-after she had been assigned to assist in the treatment of the first Ebola patient in the U.S. who had died last week.
