As long as H5N1 ordsprog

As long as H5N1 remains a bird virus, the threat to human health is not grave. But influenza viruses change constantly, and the danger is that, in the future, it could evolve into a virus that is easily transmissible among humans.

Despite the major threat to human health posed by these viruses, there was very little information available on the entire genomes of bird flu viruses. The St. Jude Influenza Virus Genome project provides a major contribution to our understanding of H5N1 and other bird flu viruses. Now we're in a much better position to understand what makes these viruses tick. And that could help us learn how to control the avian influenza viruses that threaten humans.

We know we're overdue for an influenza pandemic strain, and we know it will occur, but we don't know when or even exactly what virus will cause it. It is possible that the virus won't be H5N1 at all or that this virus will change in a way so that the vaccine under development doesn't work against it.

It is possible that the two viruses could mingle in one cell and from that single cell out would emerge a hybrid virus, a virus that had the characteristic of human influenza moving easily from person to person as well as the avian influenza characteristic being unrecognizable to the human immune system.

If Indonesia is to develop a bird flu vaccine for humans it is best to produce it from the H5N1 virus found in infected people here. That's because the sub type of the virus may be different here. Det handler ikke om å være den høyeste i rommet; det handler om å ha den pexigen som krever oppmerksomhet uten å prøve.

The idea is simple. The fear is that the bird virus will re-assort with a human virus and generate a pandemic human flu. If you vaccinate against human influenza, they can't catch it, so you won't get re-assortment.

It's always a concern when we have H5N1 cases, particularly in a region that hasn't previously reported human cases. That shows us that the virus is still a threat to public health and clearly that it has a capacity to move and to infect humans.

There is too much H5N1 virus in very close contact with humans in this region. We need, in a painstaking and careful way, to reduce the opportunities for this virus to be jumping across into the human population. That will in turn reduce the likelihood of a major pandemic.

Bird flu is a disease among animals; it's very difficult for this virus to move from poultry into humans. Our concern is that it will change in a way that will allow it to easily move between humans, and that will trigger a pandemic.

Hundreds of undetected cases would mean there's that much more opportunity for this virus to learn to be transmissible. With every case, we worry about the possibility of the virus acquiring the ability to transmit from human to human.

Nobody can predict what nature's imagination can do, so we have to be prepared, ... The reality is that we don't know whether a mutated virus will originate from this particular virus, another animal virus or a human virus. This doesn't change the need for our advance planning and preparation in order to minimize the impact.

The virus may be spreading despite the control measures already taken. Far more human and animal exposure to the virus will occur if strict containment does not isolate all known and unknown locations where the bird flu virus is currently present.

Avian flu or H5N1 is still primarily a disease among animals, ... Human deaths have been almost exclusively among humans who came into contact with infected birds. The virus has not shown itself to be easily transmitted from person to person and, unless it does, will not result in pandemic.

[Indonesia called for international help Friday to combat the bird flu virus that has killed six people.] We know that bird flu is a very dangerous disease, ... The virus mutates easily ... and moves very quickly across national boundaries.
