After the first US Ebola-confirmed patient, Thomas Duncan, died, is another Ebola suspect taken to the hospital.

Dallas' second patient is Sgt. Michael Monnig, and he had been in the room where Duncan stayed. According to Christian Post, Monnig exhibited symptoms of the virus, prompting his transport from the Frisco CareNow clinic to the Texas Health Presbyterian Hospital in Dallas.

Apparently, Monnig and two other health officials, Zachary Thompson and Christopher Perkins, got into Duncan's apartment without wearing protective equipment. This could be a possible transmission route as they reportedly entered prior to decontamination.

The City of Frisco announced, "At 12:32 p.m. today, October 8, Frisco dispatch received a call from CareNow, 301 Main Street, regarding a patient exhibiting signs and symptoms of Ebola."

The call was responded to by Frisco Fire Department's Hazardous Materials (HAZMAT) and Rescue Units, including ambulances. The firefighters-paramedics were underwent decontamination procedures by the staff in Texas Health Presbyterian Hospital after the response. This process is in accordance to the guidelines of Centers for Disease Control and Prevention.

CBS News specifies that Monnig complained of "stomach issues." Health officials informed that none of his family members showed signs and reported symptoms.

Dallas County Sheriff's Association President Christopher Dyer said via WFAA, "He's doing exactly basically what we told him to do: If at any time you don't feel well, go seek some medical attention."

"I'm being told that he's not exhibiting classic signs of the Ebola virus. It's just a matter that he doesn't feel well, and because he had contact with Mr. Duncan's apartment, they're taking every precaution," Dyer added.

The outlet wrote that it would take 48 hours before Monnig's results are out. By that time, it will be known whether or not he tests positive for the Ebola virus.

Frisco Mayor Maher Maso said that there is a minimal risk of having a new Ebola case. This could probably be the case as Monnig exhibited only a "few" clinical manifestations at par with CDC's guidelines. Maso added, "Public safety is our top priority."

As for the Duncan, according to BBC, he acquired the virus in his homeland, Liberia. He then underwent treatment by an experimental drug but to no avail. US President Barack Obama expressed his condolence saying, "Our thoughts today are with his family."

Duncan was diagnosed positive with the virus on Sept. 30. He was pronounced dead at 7:51 a.m. on Wednesday.
