Texas Governor Greg Abbott announced Saturday that he had tested negative for the coronavirus four days after testing positive. He said he would remain in quarantine at the recommendation of the doctors.

In a video posted on Twitter, Mr. Abbott, 63, attributes vaccines to protecting him from serious illness.

“I was told that my infection was short and mild because of the vaccination I received,” he said.

He added that his wife, Cecilia Abbott, continues to test negative.

Mr. Abbott, who had no symptoms of his infection and started treatment with monoclonal antibodies after his positive result, is a vocal opponent of the mask and vaccine regulation. In the days before he announced his test result, the governor attended several public events without a mask, including a crowded political gathering at a Republican club in Collin County, a hotly contested area of ​​the fast-growing suburbs north of Dallas.

In Saturday’s video, Mr Abbott said he would continue to work from the governor’s mansion and plan to focus on opening facilities across the state where coronavirus patients can receive monoclonal antibody treatments. Texas health officials hope such centers can prevent patients from becoming seriously ill and reduce pressure on overwhelmed hospitals across the state as infections reach levels not seen since January.
