Swine flu now resistant to Tamiflu

March 19, 2013

LONDON — The virus responsible for the 2009 Swine flu outbreak is becoming more and more resistant to the popular drug used to treat the illness, according to The Independent.

An increasing number of cases of the virus H1NI have developed resistance to oseltamivir — more commonly known as Tamiflu — which was stockpiled by governments around the world when it seemed like the virus would sweep the globe, the article stated.

According to the article, Tamiflu, made by the giant Swiss pharmaceutical company, Hoffman-La Roche, was the main drug against the outbreak, but Australian scientists are now finding that it is encountering increased resistance.

Dr. Aeron Hurt of the World Health Organization (WHO) Collaborating Centre for Reference and Research on Influenza in Melbourne and colleagues have analyzed circulating H1N1 strains, finding that, although the overall frequency of Tamiflu resistance was relatively low — approximately two percent of strains tested — "an increasing proportion of these viruses were being detected from patients not being treated with Tamiflu," the article noted.
