It is not licit to deny communion on the tongue due to H1N1

The Congregation for Divine Worship and the Discipline of the Sacraments responded to a lay Catholic in Britain, in a diocese in which communion on the tongue had been restricted due to concerns related to the Influenza A virus, subtype H1N1 ("Swine flu") epidemic.

It does not make any scientific sense, either, as it is better when there is just one hand involved (that of the Priest). It would seem that it would be safer to have just one man distributing Holy Communion (the Priest), no "Extraordinary ministers" of any kind, and to have all faithful receive Communion in the traditional way.
