Crowded children's hospital

Children with their parents wait their turn to receive treatment for influenza at Sohwa Children’s Hospital in Seogye-dong, Yongsan-gu, Seoul, Monday. As the flu has reached epidemic levels in the United States with over 100 deaths in 47 states, other nations are on alert with concerns over the spread of the disease. The Korea Center for Disease Control and Prevention said the H3N2 influenza in the U.S. is more virulent and deadlier than the milder H1N1 spreading in Korea. / Yonhap
