The Outbreak
HAT 1 Task 3
A. Analyze the selected communicable disease outbreak by doing the following:
Describe the communicable disease outbreak.
Avian Influenza, also known as the Bird Flu, is an influenza A virus caused by avian, which means bird. These viruses occur naturally in some birds. Wild birds in all areas of the world get the viral infections in their intestines, but do not usually become ill from them. The avian influenza is quite contagious among birds and can even kill domesticated species such as chickens, turkeys, and ducks. These birds become infected when exposed to secretions or feces from infected birds or from coming into contact with surfaces that those infected birds have come into contact with (cdc.gov). Birds, just like people, get the flu. Most bird flu viruses can only infect other birds. However, bird flu can pose health risks to people. The first case of a bird flu virus infecting a person directly, H5N1, was in Hong Kong in 1997. Since then, the bird flu virus has spread to birds in countries in Asia, Africa and Europe. Human infection is very rare, but the virus that causes the infection in birds might change, or mutate, to more easily infect humans. This could lead to a pandemic. During an outbreak of bird flu, people who have had contact with infected birds can become sick. It may also be possible to catch the bird flu by eating poultry that is not well cooked or through contact with a person who has it. Once infected with the Bird Flu symptoms occur approximately two to eight days after exposure. Infected people experience typical flu – like symptoms including fever, cough, sore throat, and muscle aches. This can progress to pneumonia and even respiratory failure. The Bird Flu can cause a very aggressive form of pneumonia, called ARDS, that is often fatal. The risk to humans from this disease is typically low. However, several subtypes of the avian influenza infection have been reported in humans since
