Argentine President Alberto Fernandez said his antigen test for COVID-19 was positive on Saturday after developing a mild fever and slight headache.

Fernandez added on Twitter that he was in self-isolation as he's awaiting further confirmation from more conclusive testing.

The announcement came on the day of his 62nd birthday.

He was inoculated with theSputnikV coronavirus vaccine on January 1, a day after the country's health regulator approved the Russian-made vaccine for use among those aged 60 and older.
