Concerns

Normally the avian bird flu viruses do not affect humans but since 1997 (when the first case of avian bird flu among humans appeared in Hong Kong), this kind of flu has infected and killed several humans in the South East Asian countries. While WHO does not recommend avoiding travels to these countries, it does advice staying away from live animal markets and poultry farms. This is because the droppings of infected birds generally carry large quantities of the virus.

1. What is bird flu Avian influenza, or bird flu, is a contagious disease that affects chickens, ducks, turkeys, and other birds. Bird flu was first detected over 100 years ago and nowadays comes in a variety of about 20 strains. Most recently, outbreaks of the viral disease have been caused by the H5N1 strain, which is a particularly deadly strain of the virus. 2. Can I be infected with bird flu The H5N1 strain of the flu, also called the Asian bird flu because it recently was detected in Asia, has a small risk level for human beings because it cannot be transmitted from one human being to another. A human being can only be infected from direct contact with a sick animal. It is possible that this could change and that the strain could evolve into a virus that can be transferred from one human to another. But this is not the case now.

Avian bird flu on the other hand is a form of flu that was originally believed to infect birds only, but turned up among humans in Hong Kong in 1997. Avian bird flu can affect humans, but only when they come in close contact with live infected birds and manage to inhale the virus. fever, malaise, sore throats and coughs.
Laptop Computers Jan 31, 2005 (AXcess News) Washington - The latest spate of deaths from bird flu in Vietnam is raising fears that the disease is re-emerging after last year's outbreak in 10 Asian countries. This time, however, there is a new, more ominous concern: A recent medical study reports the first case of bird flu transmission among humans.A report in The New England Journal of Medicine documents a probable case of person-to-person transmission of the avian flu virus in Thailand. Previous cases were traced to contact with infected poultry. In this instance, investigators from the Thai Health Ministry and the U.S. Centers for Disease Control say an 11-year-old girl died after exposure to a sick chicken, but her mother and aunt, who had no such bird exposure, also became ill, suggesting that human transmission occurred. The mother also died.The president of the vaccine division of the big U.S. pharmaceutical company Merck, Adel Mahmoud, says the new report is a sign of the virus' potential to trigger a global flu outbreak. "That is just a very, very serious warning sign that viruses are recombining, moving from avian to animals to humans and then being transmitted within the human population," he said.
3. Is there a treatment for bird flu Professionals currently researching the Avian bird flu claim that rimantidine and amantidine, two cheap and popular flu drugs, have no power over the bird flu, but Relenza and Tamiflu, two other flu drugs, can indeed effectively treat the viral disease. 4. Is there a risk of a bird flu epidemic Experts in this area suggest that rapid and extensive culling and quarantining of potentially infected animals is the best way to prevent an epidemic. Another option is vaccination of birds against the bird flu virus.
Laptop Computer Continuing spread of bird flu between people is the worst fear of public health experts. The World Health Organization's representative in Hanoi, Hans Troedsson, says this would mean that the virus has genetically altered to a form much more easily transmitted. "The major concern we have is, of course, that the virus will change or alter, but we have no indication of that yet," he said. "The other concern we have would be a dramatic increase in the number of cases even if the virus has not changed, because that would put a lot of additional pressure on the existing health care services."
This is the first case of a flock of German farm poultry contracting bird flu, the wire service reports, although several cases of the virus were found in wild birds in Germany this year. Health officials remain alert to the possibility that the avian flu virus could mutate and cause it to be transmitted from human to human. Although the World Health Organization puts the number of human deaths from avian flu at 190, none of them is ascribed to contagion between humans, the AP reports.

Notebooks the virus has not mutated and is still completely avian. Yet in a New England Journal of Medicine commentary, University of Michigan School of Public Health professor Arnold Monto expresses concern that mutation is only a matter of time. He writes that, given the continued outbreaks of this disease in Asia, the question is when such changes will happen.
