Argentine President Cristina Fernandez checked into a Buenos Aires hospital for treatment of an “infectious fever,” according to a statement issued by her office on Sunday.
The 61-year-old president entered the Sanatorio Otamendi clinic after feeling ill on Sunday afternoon, her office said.
“She decided to check herself in for observation and treatment,” said the statement, which was signed by her medical team.
The statement gave no details about the ailment besides describing it as an "infectious fever."
In mid-October, doctors told Fernandez to rest for 48 hours in order to recover from a sore throat.
The two-term president had brain surgery last year to remove a blood clot. Fernandez made no public statements for six weeks during that period, leading to concern over her condition.
