President George Bush was hospitalized in Houston on Sunday after contracting an infection that spread to his blood, his office said on Monday.

Mr. Bush, 93, was “responding to treatments and appears to be recovering,” said Jim McGrath, his spokesman.

His hospitalization at Houston Methodist Hospital came one day after the funeral for his wife, Barbara Bush, who died on Tuesday in her bedroom with the former president at her side. He was photographed at the funeral in a wheelchair with his son George W. and Laura Bush; Bill and Hillary Clinton; Barack and Michelle Obama; and Melania Trump.
