目的了解2008年广安市邻水县健康人群麻疹、白喉、百日咳、破伤风和乙型肝炎免疫水平状况,及时为免疫决策提供科学依据。方法在邻水县随机抽取7个年龄组304名健康人群作为监测对象,进行麻疹IgG抗体、白喉和破伤风抗毒素、乙肝表面抗体和百日咳凝集抗体水平检测。结果麻疹IgG抗体阳性(>200mIU/ml)有289人,阳性率为95.07%;白喉抗毒素达到保护水平的有290人,阳性率为95.39%,抗毒素平均值为0.28IU/ml;百日咳抗体阳性(≥1∶20)有295人,阳性率为97.04%,保护性抗体阳性率为66.78%;破伤风抗毒素达到保护水平的有247人,阳性率为81.25%;乙肝表面抗体阳性的有164人,阳性率为53.95%;结论广安市邻水县健康人群麻疹、白喉和百日咳抗体达到标准水平;破伤风抗毒素和乙肝表面抗体未达到标准水平,需加强免疫接种工作,提高人群免疫水平。
Objective To understand the immune status of measles, diphtheria, pertussis, tetanus and hepatitis B in healthy population of Lianshui County in Guang’an City in 2008 and to provide a scientific basis for immune decision-making in time. Methods A total of 304 healthy people from 7 age groups were randomly selected from Lishui County for detection of measles IgG, diphtheria and tetanus antitoxin, hepatitis B surface antibody and pertussis agglutination antibody. Results The positive rate of measles IgG antibody (> 200mIU / ml) was 289 and the positive rate was 95.07%. The protective level of diphtheria antitoxin was 290, the positive rate was 95.39% and the average antitoxin was 0.28IU / ml. ≥1:20), 295 were positive, the positive rate was 97.04%, the positive rate of protective antibody was 66.78%; that of tetanus antitoxin reached the level of protection was 247, the positive rate was 81.25%; 164 were HBsAg positive, The positive rate was 53.95%. Conclusion The measles, diphtheria and pertussis antibodies of healthy population in Lianshui County of Guang’an City reached the standard level. The tetanus antitoxin and hepatitis B surface antibody did not reach the standard level, and the vaccination should be strengthened to raise the immunity level of the population.
