Florida Rep. Mario Diaz-Balart and Utah Rep. Ben McAdams have become the first members of Congress to test positive for the coronavirus.

The pair announced their diagnoses separately on social media Wednesday night.

“I want everyone to know that I am feeling much better,” Diaz-Balart said in a statement. “However, it’s important that everyone take this seriously and follow CDC guidelines in order to avoid getting sick & mitigate the spread of this virus. We must continue to work together to emerge stronger as a country during these trying times.”

The South Florida Republican said he would not return to his district while infected because his wife, Tia, has pre-existing conditions that put her at a high risk.

McAdams, a Democrat, said he came down with mild, cold-like symptoms when he returned to his district Saturday from Washington, D.C. and started isolating himself on Sunday.

“My symptoms got worse and I developed a fever, a dry cough and labored breathing and I remained self-quarantined,” he said in a statement.

McAdams was tested Tuesday and received his results earlier Wednesday, he said, adding that he plans to work from home through his self-quarantine.

“I’m doing my part as all Americans are doing to contain the spread of the virus and mitigate the coronavirus outbreak,” he said.
