There is no such thing as "seasonal H1N1 strains". Gibberish.
H1N1 cases resistant to Tamiflu are quite rare.
so this is incorrect?
can you cite any references?
Antiviral Resistance:
Since October 1, 2008, 1,151 seasonal influenza A (H1N1), 264 influenza A (H3N2), 654 influenza B, and 989 2009 influenza A (H1N1) virus isolates have been tested for resistance to the neuraminidase inhibitors (oseltamivir and zanamivir). In addition, 1,051 2009 influenza A (H1N1) original clinical samples were tested for a single known mutation in the virus that confers oseltamivir resistance. Also, 1,157 seasonal influenza A (H1N1), 271 influenza A (H3N2), and 526 2009 influenza A (H1N1) viruses have been tested for resistance to the adamantanes (amantadine and rimantadine). The results of antiviral resistance testing performed on these viruses are summarized in the table below. Additional laboratories perform antiviral testing and report their results to CDC.
