The 67-year-old leader appears on a video message from the National Palace to address concerns about his condition.

Mexican President Andres Manuel Lopez Obrador said he was confident he had weathered the worst of his coronavirus infections when he reappeared in a video message to the nation.

“I still have COVID, but the doctors are already telling me that the critical phase is over,” said the 67-year-old head of the National Palace, where he has his office and official residence.

“Now I present myself to you so that there are no rumors,” he added in the video posted on social media on Friday.

“I’m fine, although I still need to rest,” he said in a calm voice.

In a suit, tie and coat – but without a face mask – you can see him walking through the National Palace for about 13 minutes and talking.

Lopez Obrador said that while in isolation he continues to work specifically on efforts to secure more vaccines for Mexico, which has one of the world’s highest death tolls from COVID-19 at more than 156,000.

The country launched a mass vaccination program on December 24, but like many other nations, it is struggling to get enough doses.

Lopez Obrador said Mexico is expected to receive six million doses from various manufacturers in February and 12 million in March if it hopes to have given all older adults a first shot.

History of heart problems

The left-wing populist, who has a history of heart problems and high blood pressure, announced on Sunday that he was undergoing treatment for COVID-19 but had mild symptoms.

He is joining other world leaders who have contracted the virus, including former US President Donald Trump, Brazilian President Jair Bolsonaro, British Prime Minister Boris Johnson and French President Emmanuel Macron.

The Ministry of Health reported Wednesday that Lopez Obrador had brief episodes of low-grade fever and mild headache.

Critics accused him of downplaying the risks of the virus at the beginning of the crisis and of being slow to impose a lockdown.

Both new coronavirus infections and deaths have set daily records this month and overwhelmed hospitals, especially in Mexico City, which has been on high alert since mid-December.
