Birds carry avian, or bird flu in their intestines. Wild migratory birds are not affected, but domestic birds get very sick, and many die. Bird flu spreads among people through airborne particles that enter the mouth or nose. People cannot get it from eating infected birds. Only a few people have been infected to date: uncommon cases of poultry workers who breathed in dust from dried bird feces; or a mutated version of the virus spreading from an infected worker to other family members. Unfortunately symptoms of bird flu resemble those of conventional flu, sore throat, cough, fever, and muscle aches. People with bird flu also may develop life-threatening complications, viral pneumonia, acute respiratory distress. Because the infection is rare, people have not built up immunity, and up to 60% of those infected, die. This along with the ability of the virus to quickly mutate, have led scientists to keep a very close watch on all known cases wherever in the world they appear.
