Lisa Schnirring, writing last night for CIDRAP News, has a terrific piece on the slow, but still worrisome spread of Tamiflu resistant H1N1 influenza strains over the past couple of years.
This is a topic this blog has covered a couple of times in recent months (see WER: Update On Anti-Viral Resistant Influenza and ECDC: Risk Assessment On Australia’s Antiviral Resistant H1N1 Cluster), but Lisa brings us details of two new studies, one in the EID Journal and the other in the Lancet.
So I’ll just step aside and invite you to read:
Signs of Tamiflu-resistant 2009 H1N1 flu transmission cited

Dec 19, 2011 (CIDRAP News) – An analysis of 2009 H1N1 influenza virus isolates from the 2010-11 flu season suggests that low-level community transmission of an oseltamivir-resistant strain took place, a development that bears close watching, researchers reported today.
Though the conclusion was based on a small number of patients, the authors said a higher prevalence of the resistant strain last year in people who weren't exposed to oseltamivir (Tamiflu) compared to the pandemic months is a notable difference. Researchers from the US Centers for Disease Control and Prevention (CDC) and their state partners reported their findings in an early online release from Emerging Infectious Diseases.
