[Analysis of influenza type A(H1N1) antibody levels in different population in Gansu province].
Objective: To investigate influenza type A(H1N1) antibody levels in 3 different population which included common people, people recovered from be infected with influenza A(H1N1) and people vaccinated influenza type A(H1N1) vaccine in Gansu province in 2009.
Methods: Hemagglutination Inhibition (HI) test, HI test is positive when HI-titer > or = 1:40.
Results: The influenza type A(H1N1) antibody-positive rate of urban population were 3.64% (11/302) and 10.45% (44/421) in Gansu province in August and later November respectively. The antibody-positive rate of people vaccinated after 30 days was 46.13% (131/284), GMT was 1:21.31. 10-15 days after infected by influenza type A(H1N1), HI antibody-positive rate was 87.04%, it rose to 96.40% after 15 days vaccination, and GMT was 1:139.4.
Conclusion: In Gansu, Influenza A H1N1 outbroke firstly among students. Currently, all age groups were reported being infected with the influenza type A H1N1 virus. Only 6.65% of residents were given vaccination, antibody level of influenza type A H1N1 in people was low. Influenza type A(H1N1) virus will continue to spread in Gansu.
