Are there medicines to treat illness associated with this virus?
CDC recommends oral oseltamivir (available as a generic version or under the trade name Tamiflu짰), inhaled zanamivir (trade name Relenza짰) and intravenous peramivir (trade name Rapivab짰) for treatment of H7N9 virus infection. Most of the H7N9 viruses that have been studied appear to be susceptible (sensitive) to the three influenza antiviral drugs that are recommended in the treatment of seasonal influenza. Those drugs are oseltamivir, zanamivir and peramivir (neuraminidase inhibitors). Like seasonal influenza viruses, avian A(H7N9) viruses are resistant to the influenza antiviral drugs known as the adamantanes.
It's important to note that all influenza viruses are evolving and may acquire genetic changes which can make one or more influenza antiviral drugs less effective. This happens with seasonal influenza viruses and could happen with H7N9 viruses in the future. As new H7N9 virus isolates are received, CDC conducts ongoing testing to determine the susceptibility of other H7N9 viruses to existing antiviral drugs.
