Epidemic keratoconjunctivitis due to the novel hexon-chimeric-intermediate 22,37/H8 human adenovirus.

ABSTRACT: In a 2-month period in 2003, we encountered an outbreak of epidemic keratoconjunctivitis (EKC) in Japan. We detected 67 human adenoviruses (HAdVs) by PCR from eye swabs of patients with EKC at five eye clinics in different parts of Japan. Forty-one of the 67 HAdV DNAs from the swabs were identified as HAdV-37 by phylogenetic analysis using a partial hexon gene sequence. When the restriction patterns of these viral genomes were compared with that of the HAdV-37 prototype strain, one isolate showed a never-before-seen restriction pattern. Within 1 year, we encountered three more EKC cases caused by a genetically identical virus: two nosocomial infections at two different university hospitals and a sporadic infection at an eye clinic. We determined the nucleotide sequences of the full-length
