Former president George HW Bush was being treated for a blood infection on Monday, hours after laying his wife Barbara to rest, his office said.
A statement stressed that Mr Bush, 93, was responding to treatment. He was admitted to Houston Methodist Hospital early Sunday, just a day after bidding a final farewell to his wife of 73 years during her funeral. Barbara Bush had died on Tuesday.
The 41st president greeted and shook hands with numerous attendees during the invitation-only funeral attended by four former presidents, including himself and his son George W Bush.
“President Bush was admitted to Houston Methodist Hospital yesterday morning after contracting an infection that spread to his blood,” a statement read.
“He is responding to treatments and appears to be recovering. We will issue additional updates as events warrant.”
Mr Bush, who suffers from Parkinson’s disease and is wheelchair-bound as a result, has been repeatedly hospitalised for pneumonia. His is a less-common version of Parkinson’s that only affects the lower body.
He is the oldest of the five living former US presidents, having served as commander-in-chief from 1989 to 1993.
Mr Bush is father to former president George W Bush (2001-2009) and former Florida governor Jeb Bush, who was a contender in the 2016 Republican presidential primaries.
