How easily are oseltamivir resistant viruses transmitted between people?
The available evidence indicates that these oseltamivir-resistant H1N1 viruses are transmissible from one person to another, but there is no evidence that the resistant H1N1 viruses are more transmissible between people than susceptible ones. Past studies in Japan suggested that low-level community transmission may occur with H1N1 viruses possessing the same resistance mutation that has been found in these recent cases. H1N1 viruses with this mutation are transmissible between laboratory animals.
