Former President George Herbert Walker Bush remains in the hospital for an eleventh straight day with no set timetable to go home.
Jim McGrath, spokesman for the former President, says he is still suffering with a painful cough brought on by bronchitis early November.
The 88-year-old Bush was admitted to The Methodist Hospital in the Texas Medical Center on the day after Thanksgiving, but before that, he spent nearly two weeks in the hospital for bronchitis treatment.
McGrath says former President Bush '41' shows signs of improvement, but doctors are taking every precaution to prevent pneumonia.
"He's being given antibiotics. A lot of it is intravenous medication. And he's doing his breathing exercises to keep those lungs functioning properly," McGrath told FOX 26 News on Monday morning. "There are a number of issues and precautions that they are taking to overcome I think the last remaining hurdle which is the cough."
McGrath says former President Bush has been dealing with Parkinson's disease for the past two and a half years, but that is not complicating his current health problems.
Former President Bush is officially listed in stable condition. Doctors say his illness has never been considered life-threatening.
The former President is also spending time reading well-wishes sent via text, e-mail, Facebook and Twitter.
Houstonians are also tweeting their well wishes to the former President. @tasha76mtz sent this tweet: #foxforlife Many Prayers to our 41st President and to his family. Many well wishes for a quick recovery.
