Health officials worry that a global outbreak could occur if a bird flu virus mutates into a form that transmits more easily from person to person. Researchers are working on vaccines to help protect people from bird flu.

Signs and symptoms of bird flu may begin within two to seven days of infection, depending on the type. In most cases, they resemble those of conventional influenza, including:. Some people also experience nausea, vomiting or diarrhea.

And in a few cases, a mild eye infection conjunctivitis is the only indication of the disease. See your doctor immediately if you develop a fever, cough and body aches and have recently traveled to a part of the world where bird flu occurs. Be sure to let your doctor know if you visited any farms or open-air markets. Bird flu occurs naturally in wild waterfowl and can spread into domestic poultry, such as chickens, turkeys, ducks and geese.

The disease is transmitted via contact with an infected bird's feces, or secretions from its nose, mouth or eyes. Open-air markets, where eggs and birds are sold in crowded and unsanitary conditions, are hotbeds of infection and can spread the disease into the wider community. Undercooked poultry meat or eggs from infected birds can transmit bird flu. Poultry meat is safe to eat if it's been cooked to an internal temperature of F 74 C.

Eggs should be cooked until the yolks and whites are firm. The greatest risk factor for bird flu seems to be contact with sick birds or with surfaces contaminated by their feathers, saliva or droppings. AI viruses are also What is chronic wasting disease? Chronic wasting disease CWD is a fatal, neurological illness occurring in North American cervids members of the deer family , including white-tailed deer, mule deer, elk, and moose.
