...that flu vaccines diminish the spread of the disease in general by cutting down on the spread of specific strains. This even extends to the vaccinations of animals that are the primary carriers of the infectious viruses. In addition, the CDC said that two major flu drugs, Tamiflu and Relenza, appear likely to diminish the severity of symptoms for the new strain, if taken in the first 48-hours of this Swine flu infection. That may be one of the reasons that public health officials, epidemiologists, and infectious disease specialists have indicated that people should not be overly concerned...
...From the volatility of global travel, investors sought the calm of safe havens. Both the dollar and the Japanese yen rose against major currencies. Defensive stocks, such as pharmaceuticals, registered healthy gains. Shares in Roche, the Swiss maker of Tamiflu, an antiviral drug effective against swine flu, had climbed almost 6% by Monday afternoon. Rival GlaxoSmithKline, which makes the influenza treatment Relenza, saw its shares rise even higher. (Read: "Swine Flu: 5 Things You Need to Know About the Outbreak...
...where cases have also been found in California, Texas, and New York City, the declaration of a public-health emergency is part of what federal officials termed an "aggressive response" to the outbreaks. In addition to releasing from the national stockpile some 12.5 million doses of the antiviral drugs Tamiflu and Relenza - which scientists say has so far been effective against the H1N1 swine flu virus - the Department of Homeland Security will begin "passive surveillance" to screen people entering the U.S. Any traveler coming from a country with a confirmed human swine flu infection will be questioned, checked for symptoms...
...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 to May--of 2007-08, 12% of circulating H1 subtypes were resistant to the drug; this season, 98% of them are. Interestingly, the mutation does not appear to be driven by overuse of the drug. In fact, rates of oseltamivir resistance are higher in nations...
...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...
