Algerian President Abdelmadjid Tebboune has left the country for treatment in Germany, less than a month after his return.
He was being treated for Covid-19 for two months until 29 December when he returned home.
The 75-year-old president will be treated for a foot problem related to the coronavirus infection, the Reuters news agency reports.
The president's two-month absence had fuelled speculation over his ability to finish his first term.
"It is hard to be far from one's country," Mr Tebboune was quoted as saying upon his return.
He had contracted the coronavirus in October when some of his close staff tested positive.
