I've expressed skepticism about the avian flu gloom and doomers (not recently, admittedly) but I have to say this is arrant bullshit. 50 more doesn't make it closer to humanizing?

There is no need to be overly concerned, the World Health Organization (WHO) announced, explaining the increase in human cases of bird flu in Turkey does not increase the risk of contagion.

There is no change in terms of the possibility of humans becoming infected with the bird flu virus, said Klaus Stohr, a WHO official, in an interview with NDR radio station.

Mr. Stohr, working as a coordinator in the WHO's influenza program, told the increase in reports of human cases of bird flu is linked directly to the lack of necessary precautions being taken, adding that a total of 50 Turkish people may have been infected with the bird flu virus.

How do outbreaks of avian influenza spread within a country?

Within a country, the disease spreads easily from farm to farm. Large amounts of virus are secreted in bird droppings, contaminating dust and soil. Airborne virus can spread the disease from bird to bird, causing infection when the virus is inhaled. Contaminated equipment, vehicles, feed, cages or clothing – especially shoes – can carry the virus from farm to farm. The virus can also be carried on the feet and bodies of animals, such as rodents, which act as “mechanical vectors” for spreading the disease. Limited evidence suggests that flies can also act as mechanical vectors.

Droppings from infected wild birds can introduce the virus into both commercial and backyard poultry flocks. The risk that infection will be transmitted from wild birds to domestic poultry is greatest where domestic birds roam freely, share a water supply with wild birds, or use a water supply that might become contaminated by droppings from infected wild-bird carriers.

So called “wet” markets, where live birds are sold under crowded and sometimes unsanitary conditions, can be another source of spread.

How does the disease spread from one country to another?

The disease can spread from country to country through international trade in live poultry. Migratory birds, including wild waterfowl, sea birds, and shore birds, can carry the virus for long distances and have, in the past, been implicated in the international spread of highly pathogenic avian influenza. Migratory waterfowl – most notably wild ducks – are the natural reservoir of bird flu viruses, and these birds are also the most resistant to infection. They can carry the virus over great distances, and excrete it in their droppings, yet develop only mild and short-lived illness.

Domestic ducks, however, are susceptible to lethal infections, as are turkeys, geese, and several other species raised on commercial or backyard farms.
