Former US president George HW Bush seems to be recovering after he was hospitalised with blood infection on Sunday hours after his wife Barbara was laid to rest, a spokesman Jim McGrath said without elaborating. The president wants to get well soon so he can go home, McGrath added. Bush has been suffering from respiratory ailments since 2012. Early last year, he spent 16 days in hospital for treatment of pneumonia. In April the same year, he spent two weeks in hospital for treatment of pneumonia and chronic bronchitis. Bush, 94, is also suffering from a form of Parkinson’s disease which makes him more vulnerable to pneumonia and other infections. When Barbara Bush was in hospital for the last time, Bush too had been hospitalised for a different reason — he wanted to be near his wife, according to his son Jeb Bush. Bush and Barbara were married for 73 years, the longest presidential marriage in US history.
