As showed above, we could draw the conclusion that H3 viruses could cause outbreaks or local epidemics in Shanghai for the immune of population to the new emerging antigenic drift was still unknown though there was strong immune barrier to the previous vaccine strain, H1 viruses also may caused epidemics as the population had a weak immune protection to the previous reference strains A/New Caledonia/20/99-like and part of the recent isolates were distingwishing from them and continued to evolute on the new reference strain, and H5N1 HPAI activities has expanded its geographical range thus increasing the size of the population at risk as the continuing emergence of human cases which give the virus an opportunity to evolve towards a fully transmissible pandemic strain. We should keep eyes on the human cases of avian influenza virus an its variation for the H5 isolates in Shanghai also has the possibility to infect human directly and the infection of H5, H9 viruses had previously occurred in the population especially in those contacting with animals.

综合上述分析结果，我们认为上海地区人群虽然对原有的H3亚型参考病毒株有较高的免疫保护，但H3亚型病毒HA已出现新的抗原漂移，人群现在对新变异株的保护水平尚未知，有可能在未来引起局限性暴发甚至地方性流行；人群对H1亚型流感病毒免疫保护水平低，同时H1亚型流感病毒株部分与原推荐疫苗株抗原性差别较大，并在现推荐疫苗株基础上继续变异，需警惕发生流行的可能性；H5N1亚型高致病性禽流感地域范围扩大，人间病例不断发生，存在演变成大流行株的威胁，上海市H5亚型禽流感病毒株存在跨宿主屏障感染人类的可能性，而且已发现人群尤其禽、畜类动物接触人群中存在H5、H9亚型流感病毒的既往感染，应警惕禽流感病毒的变异和人间病例的发生。
