...good news: you can never be complacent about a virus as fond of mutating as influenza is. We're always just a few random genetic shifts away from a possible pandemic. Researchers at the Centers for Disease Control and Prevention (CDC) last year documented for the first time that one of the many viral components that make up a common flu strain, known as H1--which also happens to be a descendant of the same virus that fueled the pandemic of 1918--was resistant to the popular antiviral drug oseltamivir, a.k.a. Tamiflu. In the flu season--October...
That means that other medications, like zanamivir, a.k.a. Relenza, or prescribing oseltamivir in combination with other drugs is still an option. But the spread of a resistant strain raises the specter of a pandemic--brought on by a flu virus that is highly contagious and invulnerable to nearly all our medical efforts...
...strains circulating in the 2007-08 season were resistant to the most popular antiflu remedy, oseltamivir, or Tamiflu. They warned that the prevalence of these strains would probably continue to increase, and indeed, early data from the current season suggest they have. Influenza is composed of three subtypes of virus, and last year 12% of one of those subtypes, known as H1, were resistant to oseltamivir. This year almost all of the H1 contingent, 98%, are resistant. (Read "Getting Closer to a Flu Supervaccine...
...need to be even more aware of how they treat the flu. "Treating flu is complicated, and we are worried that there will be some confusion among clinicians about what antiviral drugs to use," says Fry. Most do not have the time or ability to test each patient's virus to determine whether it is a resistant strain, so the CDC recommends that physicians stay updated on the predominant strains circulating in their communities. If the Tamiflu-resistant variety is common, they should prescribe either Relenza or the combination of Tamiflu and Flumadine instead...
...Rosekrans was the only other player to earn a point. “We struggled a bit,” Green said. “We had a couple of key players sick.” Freshman Camille Jania was unable to play because of a stomach virus, similar to that which had sidelined captain Laura Peterzan the previous day. Rosekrans stepped up to play in the No. 3 position, which Jania usually occupies. Rosekrans took advantage of her opportunity, defeating Joanna Dobrowolska 4-6, 6-1, 6-3. In other singles action, Harvard’s top player...
