Antiviral resistance has been reported in seasonal influenza A viruses and avian influenza A(H5N1) viruses in Viet Nam, raising concerns about the efficacy of treatment. (who.int)
Active surveillance for oseltamivir resistance among influenza viruses circulating in Viet Nam should be continued. (who.int)
The neuraminidase inhibitors oseltamivir and zanamivir are the primary antiviral agents recommended for the treatment of influenza infections, 4,5 yet antiviral resistance to influenza A viruses is increasingly being reported. (who.int)
The emergence of oseltamivir resistance of clinical isolates of influenza A virus has been associated with substitution at residue V116, I117, E119, Q136, K150, D151, D199, I223, H275 and N295 in the neuraminidase active site.8 For influenza B there have been two main substitutions: residues R152 and D198. (who.int)
7,11 The limitations of other antiviral drugs, as well as the risk of oseltamivir resistance, have raised concerns about the efficacy of oseltamivir for influenza infection treatment. (who.int)
As an initial step in establishing a surveillance programme for antiviral resistance in northern Viet Nam, genetic analysis was conducted for both clinical specimens and isolates collected through sentinel sites and isolates of influenza A(H5N1). (who.int)
