Yes. To date (14-11-08) there have been 245 human deaths due to Bird flu (H5N1)
Swine flu was first discovered in people working with pigs. Flu is a disease that is transmitted in various forms among people, pigs, and birds. Sometimes bird flu is transmitted to pigs, and sometime pig flu is transmitted to people. What actually happens is that a pig has pig flu and catches bird flu. A chromosome from the bird flu gets mixed with the pig flu and changes it to a different type of flu. Then a person with human flu catches pig flu. A chromosome with pig and perhaps bird flu mixes with the human flu. The flu is mainly human flu but contains pig and bird flu chromosomes. It got the name swine flu because people working with pigs caught it first. Because it has the pig and bird chromosomes, people with resistance to human flu, have less resistance to swine flu.
At times the chickens are dangerous to humans. They can give you bird flu. Bird flu can be lethal.
Humans and birds can die from avian "bird" flu. Up to 60% of humans who get avian flu can die.
Yes, some strains are highly contagious in humans, such as the H1N1/09 pandemic Swine Flu. Others, like the Avian (bird) flu, are not easily transmitted from person to person. Transmission of the bird flu from human to human is extremely rare.
Because it is.
it is harmful...affects human health!
None. It has not been in the US so far.
See the related questions for information about the symptoms of bird flu. It has serious effects both on poultry and birds, but especially on humans. 50 - 60 % of the humans who have caught bird (Avian) flu have died from the disease. It does not spread easily from human to human, but the mortality rate is severe. Birds, especially water fowl and poultry, must be isolated or killed if they get this flu, which can drastically impact commercial poultry farmers and economies where these operations are major employers in the community.
No. it is very rare for a human to get bird flu and only in extream cases will this result in death.
To date it has been rare for bird flu to make people sick. However the virus can evolve and when a human infection happens, there is always a strong chance that the virus will mutate and we will get human to human infection. For this reason, if bird flu is suspected in a population of domestic birds these are all destroyed.
The bird flu pandemic has happened 4 times in recorded human history. It has occurred in 1918, 1957 as the Asian flu, 1968 in Hong Kong, and in 2009 as the swine flu.
