Re: Denmark - Dane with novel H1N1 found resistant to Tamiflu
If a fit virus with Tamiflu resistance has developed and has "gotten out" then it will continue to be fit in the absence of Tamiflu treatment, and with Tamiflu treatment it will continue to out-compete non-resistant strains.
Now that seasonal flu has Tamiflu resistance it has not evolutionary pressure to remove that trait, my guess is that it didn't lose any advantages by picking that one up.
Pardon my non-gen. question, but why is that the resistance now can rapidly spread under the pressure of Tamiflu treatment,
when previously, the seasonal resistance could prevail in absence of Tamiflu treatment?
