Basel, Switzerland, 22 May 2013 – As human infections with a new avian influenza A (H7N9) virus continue to be reported in China, Lonza is making information available about infection control.

Influenza A H7 viruses are a group of viruses that usually cause infections in birds; the H7N9 is a specific subgroup of these viruses which has been seen for the first time to cause infections in humans. Human infection with influenza A (H7N9) raises global health concerns. Experts have not determined why the virus is now able to infect humans, though it is deemed likely that a genetic adaptation has led to a new ability of the virus to bind not only to avian but also to mammalian cells. Authorities continue to investigate the route of transmission, which has not yet been identified.

In general, influenza viruses are enveloped, lipophilic viruses, which are sensitive to a wide variety of chemical disinfectants. Specifically adapted strains, like H7N9, may cause severe disease and might have a pandemic potential. However, due to a general susceptibility of influenza viruses to chemical disinfection, strategies are available to help prevent transmission and infection.

Basic and general hygiene procedures are recommended to reduce infection risk. A frequent and regular hand hygiene schedule is recommended by thorough washing or use of hand sanitizers, especially before and after food preparation, before eating, after toilet use and after handling animals or animal waste. See World Health Organization instruction.

Appropriate cleaning and disinfection strategies are recommended to help control the spread of bacteria and viruses, such as the H7N9 virus. Lonza offers formulations for use as hard surface disinfectant cleaners and for hand hygiene. Multiple Lonzagard® formulations have been tested against other Influenza A strains and have demonstrated full activity.
