Erratum to “Resistance and virulence mutations in patients with persistent infection by pandemic 2009 A/H1N1 influenza” [J. Clin. Virol. 50 (2011) 114–118]

The authors regret that there is an error in the diagnosis of one of the cases described in the abstract section of the paper above. The atient included in the abstract as case 3 is described as an acute myeloid leukemia but the correct diagnosis is chronic lymphocytic eukemia as described in the main text (p. 116). The authors would like to apologise for any inconvenience this may have caused to the readers of the journal.
