    No. 1 bar-headed goose (Anser indicus) Erhel lake, Huvsgel province
    No. 3 whooper swan (Cygnus cygnus) Erhel lake, Huvsgel province H5
    No. 4 whooper swan (Cygnus cygnus) Erhel lake, Huvsgel province H5

    The above descriptions of the first samples reported to OIE from
    Mongolia show that H5 is being detected in dead birds at a remote
    lake. Media reports indicate that one of the whooper cranes has
    tested positive for H5N1 and there is little doubt that H5 from dead
    waterfowl at the lake will be H5N1 postive. The H5N1 will be
    closely related to the H5N1 from Qinghai Lake or Chany Lake.

    The above data suggest H5N1 wild bird flu is migrating to the east
    and south in Asia, while a separate wave is migrating west into
    Europe (see map). As the temperature in the north begins to fall,
    more birds will migrate out of nature reserves at Chany Lake and
    Qinghai Lake.

    H5N1 in bar headed geese, which can migrate 1000 miles in a day, is
    another indication that H5N1 can be transported far and wide by
    migratory birds. The H5N1 in the whooper swans adds to the list of
    wild bird species carrying H5N1.

    Media reports indicated that a relative small percentage of the
    birds at Erthel Lake were dead. Thus, it is likely that
    asymptomatic birds will carry the wild bird version of H5N1 into
    areas that are endemic for H5N1. This will create an environment
    for additional dual infections and recombination, which will offer
    new challenges.
