We have submitted and published the above paper in Infection and Chemotherapy in 2003. Another paper with a condensed but almost same content as the above paper was submitted to and published in an English journal (Acute Hemorrhagic Conjunctivitis Caused by Coxsackievirus A24 Variant, South Korea, 2002. Emerg Infect Dis 2003). Our original intent was to introduce the study to all readers because the two journals seemed to cover different spectrum of readers. However, we did not follow the necessary steps for secondary publication. So we are asking the permission of the Editor to retract the above paper. We hereby regret to have to retract the paper.
