Former US President George H.W. Bush has been admitted to a Houston hospital after contracting an infection that spread to his blood, a family spokesman says.
Bush, 93, was admitted to Houston Methodist Hospital on Sunday, a day after a funeral was held for his wife, Barbara Bush, spokesman Jim McGrath said on Monday.
"He is responding to treatments and appears to be recovering," McGrath said in a statement.
Bush, the country's oldest living ex-president, served a single term in the Oval Office from 1989 through 1993.
He is the father of former Republican President George W. Bush, who served two terms from 2001 through 2009, and former Florida Governor Jeb Bush, who unsuccessfully sought the 2016 Republican nomination for president.
Former US first lady Barbara Bush, the only American woman to see her husband and son both sworn in as president, died last Tuesday at the age of 92.
Barbara Bush's longtime friend, Susan Baker, the wife of former Secretary of State James Baker, described her in a eulogy at her funeral on Saturday as a "tough but loving enforcer" whose 73-year marriage to her husband was a real-life fairy tale.
