Abstract

Haemagglutinin sequences of pandemic influenza A(H1N1) viruses circulating inItaly were examined, focusing on amino acid changes at position 222 because ofits suggested pathogenic relevance. Among 169 patients, the D222G substitutionwas detected in three of 52 (5.8%) severe cases and in one of 117 (0.9%) mildcases, whereas the D222E mutation was more frequent and evenly distributed inmild (31.6%) and severe cases (38.4%). A cluster of D222E viruses among schoolchildren confirms reported human-to-human transmission of viruses mutated atamino acid position 222.
