The positive development came three days after the 41st president of the US was hospitalized at Houston Methodist Hospital on Sunday when the infection spread to his blood, his office had said. Bush, wife of former president George H.W. Bush and mother of former president George W. Bush, died at her home in Houston on April 17 at the age of 92.
Bush, 93, is expected to continue his recovery from the room for several more days.
Former President George H.W. Bush was moved out of intensive care and into a regular patient room at a Houston hospital on Wednesday as he recovers from an infection that required his hospitalization a day after his wife's funeral, a family spokesman said.
McGrath wouldn't elaborate Monday night on the specifics of Bush's condition, saying additional updates would be issued "as events warrant".
"I think Dad got sick on goal so that he could be with her", Jeb Bush said.
The program for services is seen as former first lady Barbara Bush lies in repose at St. Martin's Episcopal Church Friday, April 20, 2018, in Houston, prior to the public visitation.
According to McGrath, the 41st President has said he is determined to get healthy and get to ME this summer. His doctors "are very pleased with his progress", the statement said.
The elder Bush was hospitalized for 16 days in January 2017 for pneumonia.
Bacterial infections are treated with antibiotics, he said, while viral infections require other treatments.
The prognosis for such a case would depend on a number of factors, including heart rate, blood pressure and oxygenation, Reuben said. Born June 12, 1924, in Milton, Massachusetts, Bush also served as a congressman, Central Intelligence Agency director and Ronald Reagan's vice president.
Cronin had previously learned President H.W. Bush has an affinity for fun socks and sent him a box of the colorful socks.
