The Korea Center for Disease Control and Prevention (KCDC) confirmed Korea’s first human avian influenza infection without symptoms in an announcement yesterday.
According to the KCDC, the cases were confirmed after it carried out an antibody test on the blood serum of 318 soldiers and workers who took part in a poultry cull from December 2003 to March 2004. Four tested positive for H5N1 avian influenza virus.
Last November, the KCDC sent the serum samples to the U.S. Centers for Disease Control for a close examination and received the results back just recently.
