Afterward, all virus strains were identified. Results Of 40 influenza virus strains obtained in 1998, type H3N2 were 39 strains and type B 1 strain; of 70 influenza virus strains obtained in 1999, type H3N2 were 36 strains and type B 34 strains, of them, 1 type H3N2 and 1 type B were elected as representative virus strains in our country. The antibody level of type H1H1,H3H2and B virus strains in general population in Shenzhen was above 50.Conclusion There was no influenza epi-demic occurred in these two years.
