Cleveland, Ohio (CNN) -- Former President Jimmy Carter left a hospital in Cleveland, Ohio, on Thursday afternoon after spending two days recovering from a gastric viral infection.
He will resume his schedule with a meeting this week in Washington, a statement from the Carter Center and MetroHealth Medical Center said.
Carter thanked his medical team for "attentive and comprehensive care" and expressed appreciation to all those who wished him well.
Carter, who turns 86 on Friday, suffered stomach distress Tuesday during a flight to Cleveland, where he had planned to sign copies of his new book, "White House Diary."
He canceled that event as well as others scheduled in Washington after he was rushed to the hospital and doctors recommended that he remain under observation.
He and former first lady Rosalynn Carter are known as fitness buffs who maintain active lifestyles.
Carter recently returned from a trip to North Korea, where he secured the freedom of U.S. citizen Mahli Gomes.
During a September 20 appearance on CNN's "Larry King Live," Carter said he planned to stay busy.
"I'll stay involved in the Carter Center as long as I'm physically and mentally able," he said. "I'm still a professor at Emory University. This is my 29th year as a professor. And I'll still write a book every now and then."
