Recombinant nontypeable genotype II human noroviruses in the Americas.

Tohma K, Lepore CJ, Degiuseppe JI, Stupka JA, Saito M, Mayta H, Zimic M, Ford-Siltz LA, Gilman RH, Parra GI


We report multiple nontypeable genotype II noroviruses circulating in South America; nucleotides differed by >25% from those of other genotypes. These viruses have been circulating in the Americas for approximately 20 years and show recombination with other genotypes. Clues to norovirus natural history can guide development of treatment and prevention plans.
