American Society for Microbiology, STAT1-dependent innate immunity to a Norwalk-like virus. Pediatr Infect Dis J ; 23 10 Suppl: In summary, we have demonstrated that, in developing countries like Chile, HuCVs represent an important cause of acute sporadic gastroenteritis and that appropriate primers designed for local circulating strains significantly improve detection rates.
