Mexican President Andrés Manuel López Obrador has announced he has tested positive for Covid-19.
The 67-year-old said on Twitter that his symptoms were mild and that he was optimistic following the diagnosis.
The development comes as Mexico grapples with an upsurge in infections, with deaths close to one hundred and fifty thousand.
Mr López Obrador says he will continue working from home, including speaking to President Vladimir Putin about acquiring a Russian-made vaccine.
The Mexican president has earlier said he would try and acquire 12 million doses of the Russian-made vaccine if it proved effective.
