摘要
通过流感病毒分离、人群流感抗体水平测定和流行病学调查对 2 0 0 1年度 (2 0 0 1年 3月至 2 0 0 2年 3月 )湖北地区流感疫情进行了分析。结果表明 :本年度湖北武汉地区出现过两次流感季节性小流行 ,第一次在 2 0 0 1年 8～ 9月 ,主要由甲 1型流感病毒引起 ;第二次在 2 0 0 1年 12月至 2 0 0 2年 1月 ,以甲 3型流感病毒占优势。从病毒分离鉴定和抗体水平测定的情况分析 ,这次流行的甲 3型流感病毒与 1999年分离的毒株相比 。
The influenza epidemic situation in the epidemic year of March 2001 to March 2002 in Hubei area was analyzed according to the results of isolations of \%Influenza viruses\%, detection of human antibodies against \%Influenza viruses\% and epidemiological survey. It was concluded that there were two epidemics during the epidemic year. One in August and September of 2001 was mainly caused by A1 type of \%Influenza viruses\%. Another was caused by the dominant strains of A3 type. It was also shown that the isolated strains of A3 type during this epidemic year likely underwent some antigenic draft, compared with the A3 type of \%Influenza viruses\% isolated in 1999.
