为了解河北省麻疹网络实验室运转情况 ,对 1999～ 2 0 0 1年麻疹网络实验室的运转状况进行了评价。结果显示 :1999～ 2 0 0 1年共报告麻疹疑似病例 170 1例 ,采集合格血清标本 12 4 2例 ,证实麻疹病例 5 98例 ,麻疹IgM抗体阳性率为 4 8 15 % (5 98/12 4 2 ) ;采血后 3d和≤ 6d报出检测结果率分别为 4 9 76 %和 70 6 9% ;证实的麻疹爆发 (每起≥ 2例 ) 2 8起 ;麻疹IgM抗体阳性病例主要为麻疹疫苗零剂次免疫、1剂次免疫和免疫史不详者 ,占 75 5 9%(45 2 /5 98)。 2 0 0 0年和 2 0 0 1年对各市网络实验室考核结果符合率≥ 90 %。表明麻疹网络实验室对麻疹疑似病例的监测起了重要的作用。 To understand the operation of measles network laboratory in Hebei Province, the operational status of measles network laboratory from 1999 to 2001 was evaluated. The results showed that a total of 170 suspected cases of measles were reported from 1999 to 2001, 12 4 2 cases of qualified serum samples were collected, and 5 98 cases of measles were detected. The positive rate of measles IgM antibody was 48.15% 4 2). Detection results were reported at 4 9 76% and 70 6 9% on 3d and 6 days after blood collection, respectively. A total of 28 confirmed measles cases (≥ 2 cases each) were found. Measles IgM antibody positive cases were mainly measles Zero-dose immunization of vaccines, immunization of one dose and unknown history of immunization accounted for 75 59% (45 2/588). In 2000 and 2001, the results of network laboratories in all cities met the agreement rate of ≥ 90%. This indicates that Measles Network Laboratory plays an important role in the monitoring of suspected measles cases.
