Japan : New flu virus resistant to antiflu drug Rapiacta detected in patient

Via Japan Today :

" TOKYO : A genetic mutation of the H1N1 influenza virus resistant to the Rapiacta anti-influenza drug has been detected in a 5-year-old patient, according to the National Institute of Infectious Diseases. It is likely the first case in Japan concerning a patient treated with the intravenous drip medicine introduced in January 2010.

According to a report recently posted by the institute on its website, a genetic mutation was found in a virus from the child who was treated with Rapiacta after testing positive for the type A influenza virus last month. ‘‘This is only one case and there is no need to worry,’’ said Takato Odagiri, head of the Influenza Virus Research Center at the institute. ‘‘We need to carefully watch how frequently such a virus resistant to Rapiacta appears."
