Late yesterday Russian language media began talking about an outbreak of avian flu at a large poultry production facility near Moscow. This morning we have two official reports confirming the outbreak, along with some less-than-official media reports suggesting some number of exposed workers have been hospitalized with `flu-like' symptoms.
This being flu season, the finding of some workers with flu symptoms is hardly unexpected, and they may be completely unrelated to the outbreak. But when there has been history of exposure to infected birds, all cases must be checked out.
First stop, a report from Russia's Federal Service for Veterinary and Phytosanitary Surveillance (Rosselkhoznadzor).

This statement from the Russian Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing (Rospotrebnadzor) for the Moscow Region, deals more with the prevention of human infection with the virus:
Federal Service for Supervision of Consumer Rights Protection and Human Welfare in the Moscow region informs about the registration of epizootic outbreak of influenza in birds FGBU SGC "Change" Sergiev Posad municipal district of Moscow region since the beginning of March this year.
Specialists of Rospotrebnadzor in the Moscow region organized complex of anti-epidemic and preventive measures aimed at preventing the spread of infection among humans, including organized homestead detours and daily medical observation of contact persons, carried out explanatory work with the population on the rules of the content of poultry, distributed leaflets about prevention avian influenza; established control over implementation of agricultural products (poultry, poultry eggs) and the destruction of all dead birds.
When the Administration of the Sergiev Posad municipal district created operational headquarters for the elimination of the arisen fire.
In connection with the above, the Office of Rospotrebnadzor in the Moscow region recommends the following preventive measures:

Symptoms of bird flu in humans.
The incubation period of avian influenza may be longer than the normal seasonal flu and lasts an average of 5 days (from 2 to 8 days, maybe even up to 17 days).
The disease begins acutely with chills, fever up to 38 ° C and above, muscle and headaches, pain in the throat. Chance of watery stools, repeated vomiting. Condition is rapidly deteriorating. After 2-3 days appears cough, often mixed with blood, shortness of breath. Then it may be difficulty in breathing. Perhaps the liver, kidneys and brain.At the first signs of the disease an urgent need to consult a doctor for diagnosis and appointment of adequate and timely treatment, as the late start of treatment inevitably leads to the development of complications.
While I've yet to locate an official statement, Russian media also reports as many as 14 people have been hospitalized or placed in quarantine due to possible exposure and/or symptoms.
Although human infection is possible - even with H5N8 - all of this may prove nothing more than the prudent exercise of an abundance of caution.
This from the Interfax News Agency:
