Mexico’s president, Andrés Manuel López Obrador said Sunday that he had contracted the coronavirus and was undergoing “medical treatment” for what he described as mild symptoms.
Mr. López Obrador, writing on Twitter, said he would continue to carry out his official duties, including holding a call with President Vladimir V. Putin of Russia that is set for Monday.
“As always, I am optimistic,” he said.
The Mexican leader has consistently downplayed the pandemic, questioning the value of wearing masks and refusing to put one on himself in most public appearances.
On Friday, he posted a photo of himself indoors, again without a mask, conducting a call with President Biden. He was surrounded by Marcelo Ebrard, the foreign minister, Martha Bárcena, Mexico’s departing ambassador to the United States, and Alfonso Romo, a former top aide — none of whom were wearing masks. On Saturday, the president met with local business leaders in Monterrey.
The news comes as Mexico confronts its worst moment since the pandemic began, as deaths and infections hit horrific new highs. On Thursday, Mexico confirmed 1,803 new coronavirus deaths, surging past the previous record of more than 1,500 set days earlier. The country’s hospitals are overrun.
