Two health care workers at the Orlando, Fla. hospital treating a confirmed Middle East Respiratory Sydrome patient are showing symptoms associated with the virus.

Dr. P. Phillips Hospital, where the MERS patient is being treated, confirmed to TIME that two health workers are experiencing flu-like symptoms. One has been hospitalized, while the other is currently isolated at their home, and is being monitored. Neither has yet been diagnosed with MERS, the hospital said.

A total of 20 health care workers at Dr. P. Phillips Hospital are now undergoing testing for MERS after being exposed to the patient, the hospital confirmed to TIME. The virus is not a severe risk to the general public, but human transmission appears to happen among people who interact with those who are infected, typically in a health care setting.

Like the first patient in Indiana, the new patient lives in Saudi Arabia and is a health care worker there. The patient flew from Jeddah to London, and then to Boston, before traveling to Atlanta and finally Orlando to visit family. The patient started feeling ill during the flight from Jeddah to London, and had symptoms like fever, chills and a slight cough. The patient visited the emergency room at an Orange County hospital, and was isolated.

MERS is a respiratory virus that is in the same family as the common cold and Severe Acute Respiratory Syndrome (SARS). The disease appeared two years ago in Saudi Arabia, and to date, there are over 500 total cases, and over 100 deaths. The Center for Disease Control and Prevention (CDC) says the risk to Americans is extremely low, and there are currently no travel restrictions in place.

White House press secretary Jay Carney said earlier today that President Obama has been briefed on the two cases of MERS in the U.S, and that the White House is “watching this very closely.”

The MERS patient is Florida is said to be in stable condition, and the first patient in Indiana has already been discharged from the hospital.
