Former US president George HW Bush is in a hospital recovering from a mild case of pneumonia, his office said.
The 41st president "was admitted to Houston Methodist Hospital on Friday for observation due to a persistent cough that prevented him from getting proper rest," the office said in a statement released by Bush spokesman Jim McGrath.
Doctors later determined that the 92-year-old had a mild case of pneumonia, "which was treated and has been resolved," the statement said.
"President Bush is in very good spirits and is being held for further observation while he regains his strength."
Mr Bush spent two weeks in January in the same hospital where he was treated for bacterial pneumonia.
He served as US commander-in-chief from 1989 to 1993, and is the oldest of the five living former US presidents.
He is father to former president George W. Bush and former Florida governor Jeb Bush, who was a contender in the 2016 Republican presidential primaries.
