Former President George HW Bush was readmitted to the hospital on Tuesday with a 'mild case' of pneumonia, his spokesperson said.
Bush, 92, received treatment at Methodist Hospital in Houston but is now said to be doing fine, according to KHOU.
'He is already well on the path to recovery and going home,' the spokesperson, Jim McGrath, said.
In March, Bush seemed to have fully recovered from the bout of pneumonia that kept him in the hospital for two weeks earlier this year as he and his wife Barbara picked up an award for their service to the Jewish community.
In January, Bush came home from the hospital, where he spent some time in the ICU and needed a breathing tube for a couple of days.
His wife, 91-year-old Barbara, kept him company after being hospitalized for five days and receiving treatment for bronchitis.
The illnesses kept the couple from attending the presidential inauguration on January 20, with their son George W Bush announcing that he and his wife Laura would represent them instead.
Before the inauguration, the elder Bush sent a letter to Donald Trump saying that his doctor had told him that going to the event would put him 'six feet under'.
The elder Bush and his wife, who were married 72 years ago on January 6, 1945, have had the longest marriage of any presidential couple in American history.
Their family kept giving supportive updates throughout their hospitalization.
A spokesman told the DailyMail.com after Bush was released from the hospital that his son and fellow former president was happy to know his father was back home.
'43 is just thrilled that 41 is home and well,' the younger Bush's spokesman Freddy Ford said, calling George Bushes by their numbers in the order of US presidents.
