Denver Health paramedics moved a patient to the Denver Health Medical Center on Monday morning to be monitored for the Ebola virus.

The patient, whose name has not been released, recently returned from an area in West Africa affected by the virus. Previously, the patient was being monitored outside of the hospital in compliance with Centers for Disease Control and U.S. Homeland Security protocols for travelers coming from affected regions. The patient is now in isolation at the hospital.

“The person being monitored for Ebola symptoms (is) considered low risk,” according to the Colorado Department of Public Health and Environment (CDPHE). “We’re exercising extreme caution.”

Initially, the hospital was going to test the patient for the Ebola virus. However, the CDPHE has since decided that the current symptoms presented do not warrant testing at this time. The patient is considered to be very low-risk and will be monitored as a precaution.

“We are taking all the necessary precautions to protect both our patients and staff, even though the infection with the virus is not confirmed,” said Dr. Connie Price, Denver Health’s chief of infectious diseases, according to USA Today. “We have staff trained specifically to assist with patients who may have contracted the Ebola virus.”

The ambulance used to transport the patient to Denver Health has been taken out of service until the observation is complete.

Symptoms of the Ebola virus are similar to the flu in the beginning and can appear anytime from two to 21 days after exposure to the virus. These symptoms include fever, headache, muscle pain, vomiting, and unexplained bruising or bleeding.

While often deadly, it’s important to note that the virus is very difficult to catch. The Centers for Disease Control note that the virus cannot be spread by air, water, or food in general. Infection occurs only if the person has come into contact with an infected patient’s bodily fluids.
