Molecular epidemiology of adenoviruses isolated from hospitalized children with severe lower acute respiratory infection in Santiago, Chile

Genome analysis was performed on 69 adenovirus isolates from pharyngeal secretions of young children hospitalized with severe lower acute respiratory disease in Santiago, Chile, between 1984 and 1986. As expected, most isolated strains belonged to subgenus B (68.1%). Among the isolates of 1984, Ad7c was the dominant genotype (12 out of 23). The majority of isolates of 1986 were of the recently described genomic variant 3f.
