Influenza virus is very hard to treat, because of its very high mutation rate. That's why public-health measures like prompt slaughter of exposed fowl and swine are so vital.
There are no magic bullets against this virus at this time. Which is not the same thing as saying no way to fight the virus.

No magic bullet. More like a bandaid.
The clinical utility of this agent (and zanamavir) has never been compared with amantadine and rimantidine in a head-to-head trial AFAIK, but in practice the older drugs are much more potent.
In the rare human cases of H5N1 disease, death is fairly rapid, thus, it would be surprising if basically weak drugs had any effect at all.
Tamiflu must be administered within the first 24 hours of onset.

I wonder how fast the onset of severe symptoms are with bird flu. Do you go straight into check-into-the-hospital sick or do you start with a headache and a tingle in your throat that takes a day to manifest itself into something worse?
Well, that's nice to know.
When it not only won't help the patient, but when it will have an increased likelihood of selecting (sorry, "intelligently designing") resistance in future generations of the virus. You'd think doctors, even in Asia, would know this ... But Noooooooo! Follow the instructions, guys ... Please!
Not as easy as it sounds. H5N1 sneaks up pretty quickly, and the first symptoms seem like the flu, or even a bad case of the common cold.
Many people don't come into the hospital for such things, and so when they do, it's progressed to a severe stage and Tamiflu may no longer be effective. Also, this strain of avian flu seems to be entering patients, and they are asymptomatic until it's too late to do anything.
Everyone [who has any] will be taking Tamiflu at the first symptom they think is a flu symptom.
Why would anyone have Tamiflu if it has not been prescribed by a doctor?
I read here that several FReepers already had doses of something [I thought it was Tamiflu] socked away, just in case. It's been over a week, so I don't recall the thread.
Well, if they want to waste their medicine in a panicked state, then they may not have it when it counts. Their loss.
Thanks for posting the article.

If I recall correctly, Tamiflu is effective against some strains of the H5N1 virus--China, never a very reliable reporter, insists that it is effective in the Chinese strains. That may be because Chinese farmers were routinely using amantadine (again, if I remember correctly) to prevent avian flu in their flocks.
The VN strain has been shown to be more resistant to Tamiflu, although anyone who has survived has been treated with it. Some authorities say the dose should be doubled to be effective, but I have a concern that the side effects may be more severe.
Amantadine is a very potent drug with severe side effects used to treat Parkinson's. At one time I thought it would be very useful. I no longer think so.
On the other hand, in the worst case scenario, who wouldn't try everything possible for hope?
However, the 75mg dose is almost certainly too low, and five days is not enough.
If I ever get infected with H5N1, I plan to take 150 mg Tamiflu BID together with 100 mg rimantidine BID for possible synergy.
