Paraguayan President Fernando Lugo has left his No. 2 in charge while he travels to Brazil for an emergency procedure to treat an infection. Dr. Lugo Eugenio Baez says surgeons will drain a buildup of fluids in Lugo's neck that was caused by a dental infection, AP reported. The 59-year-old president will be at Sao Paulo's Sirio Hospital, where he has also been undergoing treatment for non-Hodgkin's lymphoma. Hematologist Alfredo Boccia said Lugo is at high risk for infection because chemotherapy has lowered his white blood-cell count. Under the constitution, Vice President Federico Franco is running the country for the next five days.
