A nurse cares for a patient suspected of suffering from pneumonia at a hospital in the western Ukrainian city of Lviv, Tuesday, Nov. 3, 2009. Urging its citizens not to panic, Ukraine on Monday closed down all schools nationwide for a week to avoid the spread of swine flu and suggested that night clubs, cinemas and food markets in the west also shut down. The World Health Organization said Monday there was no evidence that Ukraine had a bad outbreak of swine flu but at the government's request it had sent a health team in to help the country cope.
