Recent progress of the laboratory in the area of the search and development of novel remedies for prophylaxis and treatment of influenza is reviewed in this work. The data of the study of the anti-viral activity of compounds from the chemical groups of azolo-adamantanes, triterpenes, derivatives of benzimidazole, usnic acid, and other heterocyclic substances are presented. The protective properties of the plant antioxidants at lethal influenza infection of animals are discussed. High virus-inhibiting activity of natural polysaccharides and their complexes with silver ions is shown against influenza virus. The data presented allow listed groups of compounds to be suggested as promising candidates for further development of anti-influenza drugs.

In North America, infections in novel avian and mammalian species suggest the potential for changing ecology and establishment of new animal reservoirs. Outbreaks among domestic birds have persisted despite aggressive culling, necessitating a re-examination of how these outbreaks were sparked and maintained.

The I38T substitution in the influenza virus polymerase-acidic (PA) subunit is a resistance marker of concern for treatment with the antiviral baloxavir marboxil (BXM). Thus, monitoring PA/I38T mutations is of clinical importance. Here, we developed three rapid and sensitive assays for the detection and monitoring of the PA/I38T mutation.
