The World Health Organization was cited as saying yesterday that a strain of avian flu that is resistant to the antiviral drug oseltamivir has been isolated from two family members in Egypt.
The story says that the development is potentially dangerous because oseltamivir, commonly sold under the name Tamiflu, is the chief weapon against the flu strain, H5N1, which many worry could mutate into a strain that could set off a worldwide pandemic.
The health organization emphasized that it was too early to tell whether the resistant strain had developed independently in the two patients, who were both under treatment with the drug, or whether they had picked it up from birds or from each other. The resistant strain did not spread to anyone else, including a third family member who also had avian flu.
