Former United States President, George Herbert Walker Bush has been hospitalized in Houston for a blood infection, two days after attending the funeral of his wife, Barbara.

According to Jim McGrath, a spokesman for the family, the 93-year-old Bush was admitted to Houston Methodist Hospital on Sunday morning after an infection spread to his blood, adding that he was responding to treatment and appears to be recovering.

Bush uses a wheelchair and an electric scooter for mobility after developing Parkinson’s disease and has needed hospital treatment several times in recent years for respiratory problems.

Born on June 12, 1924 in Milton, Massachusetts, Bush who served as the United States President from 1989 to 1993 had a year ago spent two weeks on the treatment of pneumonia and chronic bronchitis.

He was also hospitalized in 2015 in Maine after falling at home and breaking a bone in his neck while in December 2014, he was  hospitalized for about a week for shortness of breath.
