Colombian President Alvaro Uribe has the swine flu.
Social Protection Minister Diego Palacio says the 57-year-old Uribe is not considered a high-risk patient and his case is "developing satisfactorily". He is being treated at the presidential residence.
Palacio said on Sunday that Uribe began feeling ill on Friday, the same day as a summit of South American leaders in Bariloche, Argentina that he attended. He was confirmed to have the swine flu on Saturday.
Colombian officials are contacting leaders and officials who may have had contact with Uribe during the summit.
Colombia has reported 621 confirmed cases of the swine flu with 29 deaths, according to the social protection ministry.
