From a correspondent:
about TRANSSIBERIEN
I never believe this hypothesis !
i know very well russian trains
sure, it’s many, many very poor great mothers which travel with bucket of eggs or chicken from their vllages to the next town
but not sufficient !
for me, transiberian appears one day in the russian press agencys; after the departure of migrating birds !
it was a new reason to distract from poultry industry
if really transsiberian, why not bird flu in Moscow or Vladivostok 
)))))))
why, after Ural, direct to the south -without transsiberian -? to Volga and Don ?
in Russia, very few roads, very few trains
I’m fast sure that the poultry industry don’t take train, but trucks which travel through all the country with the virus !
and in russia, no sense of hygiene
