| Abstract: |
| 自1979~1983年对北京地区686例肺炎患儿进行肺炎支原体血清流行病学调查的结果表明,支原体肺炎占小儿肺炎总数的13%,按年度计算每年发病占肺炎病例的4~21.9%。1979及1983年的发病较高,出现约隔四年一次新的发病高峰。1983年流行时,全年各月份均有病例发生,但11月最高。流行期长,推测与带菌期及潜伏期长有关。发病年龄多为学龄期儿童。1983年春在两个小学校调查的结果发现,肺炎支原体感染班中有呼吸道感染症状者各为51.4%及52.6%。血清抗体阳性者各占34.2%及43.2%。说明肺炎支原体感染是较常见的一种呼吸道疾病。 |

| From 1979 to 1983, an epidemiological study was carried out in 686 cases of children pneumonia by serological study to determine the incidence of Mycoplasma pneumoniae infections. The results indicated that the percentage of M.pneumoniae was found to be 13%, with annual ratio ranged between 4 to 21.9%. The highest ratio occured in 1979 and 1983, indicating the possibility of a cyclic epidemic every 4 years. In 1983, the epidemic of M.pneumoniae infection lasted throughout the whole year with highest incidence in December. M.pneumoniae infections are most prevalent in school children. In 1983, a study for M.pneumoniae infection was carried out in 2 primary schools. Respiratory symptoms were noticed in 51.4% and 52.6% of the pupiles of the infected classes and the serologically proven attack rate was 34.2% and 43.2% respectively. These results suggest that M.pneumoniae infection is more frequent than what is known in the past. |
