After a tough summit with South America's leaders, Colombian President Alvaro Uribe discovered he had come down with swine flu. Officials are contacting the other leaders who were at the summit, where Uribe was harshly criticized for agreeing to allow U.S. troops to use Colombian bases, to make sure they do not also have the virus. Uribe is the second president in Latin America to contract the disease. Oscar Arias, Costa Rica's leader, was quarantined after he announced he was ill in August, and has since recovered. Uribe's spokesman said he will continue to handle his duties as he recovers.
