Mexico's President Lopez Obrador tests positive for COVID-19, says symptoms are mild

MEXICO CITY -- Mexican President Andrés Manuel López Obrador said Sunday he has tested positive for COVID-19.

Lopez Obrador, 67, said he was receiving medical treatment and his symptoms are mild.

"As always, I am optimistic," he tweeted.

Lopez Obrador took office as president in December 2018.

He is among a number of world leaders who have contracted the virus during the pandemic. Most have since recovered. Among them: Boris Johnson of Great Britain, Emmanuel Macron of France, Jair Bolsonaro of Brazil, and former U.S. President Donald Trump.

Ambrose Mandvoul Diamini, the prime minister of Eswatini - the southern Africa nation also known as Swaziland - died in December 2020 about a month after a positive test for COVID-19.
