Former US first lady Barbara Bush remains hospitalised in the Houston city of the US for treatment of a respiratory-related ailment Thursday, a family spokesperson said.
Mrs. Bush is "doing great and responding well" to treatment at Methodist Hospital in Houston, Texas state, reported Xinhua citing Bush family spokesperson Jim McGrath telling media Thursday.
McGrath said physicians may be exercising extra caution by keeping her at the hospital.
