Annual trends of adenovirus type 8 (Ad8) genome types in Hiroshima. The distribution of Ad8 genome types in Hiroshima on a yearly basis. Ad8A (A) and Ad8B (B) were co-circulating from 1983 to 1988. Ad8E (E) was co-circulating with Ad8A and Ad8B from 1984 to 1988 and circulated as a single genome type from 1989 to 1995. A new genome type Ad8I (I) was isolated from the outbreak of epidemic keratoconjunctivitis in 1995. All 66 cases from the outbreak were Ad8I. Ad8I was subsequently recovered from sporadic cases in 1996 and 1997.
