Someone who attended the Conservative Political Action Conference (CPAC) last week in National Harbor, Maryland, has been diagnosed with the coronavirus, and the state's governor says anyone who attended may be at risk.

The New Jersey health department notified Maryland officials of the case on Saturday, Maryland Gov. Larry Hogan said in a statement Saturday evening.

Anyone who "attended or worked at the conference may be at some risk for acquiring COVID-19," the statement said.

Sen. Ted Cruz, R-Texas, and Rep. Paul Gosar, R-Ariz., both self-quarantined after having contact with the patient at CPAC.

President Donald Trump and Vice President Mike Pence attended CPAC but "there is no indication" they "met with or were in close proximity to the attendee," a White House spokeswoman said in a statement.

"The President’s physician and United States Secret Service have been working closely with White House Staff and various agencies to ensure every precaution is taken to keep the First Family and the entire White House Complex safe and healthy," the White House said.

The Maryland governor's office said they had been in contact with the White House.

Anyone who went to CPAC should be aware of any flu or cold symptoms they have, Hogan said.

“Due to the scale of this conference, we are urging attendees who are experiencing flu-like symptoms to immediately reach out to their health care provider," he said in a statement.

Trump addressed the right-wing conference on Feb. 29 for the fourth straight year. The event was held Feb. 26-29 at the Gaylord National Resort & Convention Center.

The coronavirus patient was in Maryland Feb. 27 to March 1.

Information was not immediately released on anywhere else the patient may have gone or how they traveled to Maryland.

"Maryland residents who have questions about this information are encouraged to contact 2-1-1 to talk to a helpline representative," the governor's office said.

The Maryland Department of Health went to the Gaylord National Resort & Convention Center to hold an educational talk for employees.
