Anti-influenza drugs play a vital role in the prevention and treatment of influenza A. There are three kinds of anti-influenza drugs for treatment: NA inhibitors such as oseltamivir; RNA polymerase inhibitors such as baloxavir (mainly targeting PA); and M2-type ion channel blockers that inhibit the virus’s release of nucleic acids to host cells, such as amantadine and rimantadine [11,12]. The gene discussed is XK; the disease is influenza.
