Antiviral Drugs and Swine Influenza

Antiviral drugs are prescription medicines (pills, liquid or an inhaler) with activity against influenza viruses, including swine influenza viruses. Antiviral drugs can be used to treat swine flu or to prevent infection with swine flu viruses. These medications must be prescribed by a health care professional. Influenza antiviral drugs only work against influenza viruses -- they will not help treat or prevent symptoms caused by infection from other viruses that can cause symptoms similar to the flu.

There are four influenza antiviral drugs approved for use in the United States (oseltamivir, zanamivir, amantadine and rimantadine). The swine influenza A (H1N1) viruses that have been detected in humans in the United States and Mexico are resistant to amantadine and rimantadine so these drugs will not work against these swine influenza viruses. Laboratory testing on these swine influenza A (H1N1) viruses so far indicate that they are susceptible (sensitive) to oseltamivir and zanamivir.

A Phase 4 alert is characterized by confirmed person-to-person spread of a new influenza virus able to cause “community-level” outbreaks.” The increase in the pandemic alert phase indicates that the likelihood of a pandemic has increased.

CDC has activated its emergency operations center to coordinate the agency’s emergency response. CDC ’s goals are to reduce transmission and illness severity, and provide information to help health care providers, public health officials and the public address the challenges posed …

This Gigapan was shot from a pedestrian bridge that was seriously shaking as people were walking by. Still, the images are relatively sharp and the panorama stitched pretty well, the only effect of the shaking being the somewhat irregular panorama boundary.
