Phylogenetic tree based on HA and NA nucleotide sequences of A(H3N2) from 2009 to 2020. Phylogenetic analysis of HA and NA gene sequences was performed with the General Time Reversible and Tamura 3-parameter model respectively which were the best fit for our data using MEGA software version 11.0, with gamma-distributed rates. The reliability of the maximum-likelihood tree was run by bootstrap analysis with 1000 replications. Filled triangle represents the vaccine strain. Red represents viral strains from immunosuppressed patients and blue represents viral strains from immunocompetent patients
