Confirmed Human Bird Flu Infections

(Korea) These cases resulted from close, sustained contact with infected birds.

From Chosun.com:

Korea on Friday confirmed four infections with the deadly human strain of bird flu in the country.

The Korea Center for Disease Control and Prevention said the four tested positive for antibodies of the H5N1 strain of avian influenza but showed no symptoms of the disease, meaning their immune systems overcame the infection.

So, we've seen the bird flu spread from Asia to Europe to Africa. New cases surface in new places almost daily. And, sooner or later, we'll see humans infecting humans. (H/T: Robert Koehler)
