Former President George H.W. Bush is awake, alert and talking after he was admitted to intensive care earlier this week, a family spokesman said Tuesday.
Bush, 93, was admitted to the Houston Methodist Hospital Sunday morning after contracting an infection that spread to his blood, family spokesman Jim McGrath said, a day after a funeral was held for his wife, Barbara Bush.
According to McGrath, the 41st President has said he is determined to get healthy and get to Maine this summer. On Monday, McGrath said Bush was "responding to treatments and appears to be recovering."
According to a source close to the former Republican President, Bush was admitted to the hospital with an infection that led to sepsis, which can be life-threatening. He was in critical condition, the source said.
The source added that Bush's blood pressure kept dropping and a couple of times there was serious concern about whether he was going to come through, but that he had been stabilized.
But with Bush's age, his health and with this infection, this is very serious, the source explained.
Speaking at a ceremony to welcome French President Emmanuel Macron to the White House on Tuesday, President Donald Trump offered his prayers for Bush and his family, and wished the 41st President a "speedy recovery."
Bush revealed several years ago he suffers from a form of Parkinson's disease, which has left him unable to walk, so he gets around either in a wheelchair or a scooter.
The former President's hospitalization is especially upsetting for his family because it follows so closely on the death of his wife of 73 years last Tuesday. The family had been worried about how he would deal with her death and such an emotional week, according to the source.
"Right after a big loss -- certainly like he has had -- there is some data that shows that some people can develop problems with immunity and become more susceptible to infections," CNN chief medical correspondent Dr. Sanjay Gupta said. "Infections they otherwise would have been able to fight become more serious."
The day after his wife's death, the former President paid tribute to her in a statement.
"I always knew Barbara was the most beloved woman in the world, and in fact I used to tease her that I had a complex relationship about that fact. But the truth is the outpouring of love and friendship being directed at The Enforcer is lifting us all up," he said, using her nickname.
"We have faith she is in heaven, and we know that life will go on -- as she would have it. So cross the Bushes off your worry list."
