On episode #230 of the science show This Week in Virology, Vincent, Rich, Alan and Kathy review H7N9 infections in China, the debate over patenting genes, and receptor-binding by ferret-transmissible avian H5 influenza virus. You can find TWiV #230 at www.microbe.tv/twiv.
In early 2012 influenza virus researchers around the world decided to stop working on highly pathogenic avian influenza H5N1 virus. This decision came after work from the Fouchier and Kawaoka laboratories revealed the isolation of influenza H5N1 strains that can be passed among ferrets by aerosol. The moratorium on influenza H5N1 virus research has now …
On episode #190 of the science show This Week in Virology, Vincent, Alan, and Kathy review selection of influenza H5N1 viruses that can transmit among ferrets by aerosol. You can find TWiV #190 at www.microbe.tv/twiv.
Influenza virus may be transmitted among humans in three ways: by direct contact with infected individuals; by contact with contaminated objects (called fomites, such as toys, doorknobs); and by inhalation of virus-laden aerosols. The contribution of each mode to overall transmission of influenza is not known. But something that most of us touch on a …

While perusing the cleaning items at the supermarket last night, I spotted the words ‘Kills Flu Virus’ on a bottle of toilet bowl cleaner. Do toilets play a role in transmission of influenza? Influenza is an infection of the respiratory tract. The virus enters the tract in aerosols or by contact with saliva or other …
The isolates of influenza virus obtained in the current global outbreak have proven to be resistant to the adamantane antivirals, but susceptible to oseltamivir (Tamiflu) and zanamivir (Relenza). Consequently the two neuraminidase inhibitors will likely be used extensively to control the outbreak until a vaccine is available. Extended use of the antiviral drugs will undoubtedly …
