目的研究广州市白云区≤4岁麻疹病例发病危险因素及探讨麻疹防治对策。方法调查白云区≤4岁麻疹病例385例,收集病例就诊情况、乘坐交通工具情况、免疫史及相关信息,与麻疹个案调查表进行整合分析。结果8个月～4岁麻疹病例23.1%发病前有麻疹疫苗(MV)接种史,7.22%病例发病前3周内有MV接种史,30.13%麻疹病例发病前3周(最长潜伏期)内有就诊史,29.16%病例发病前3周内有乘坐交通工具史,6.23%病例发病前3周内有现症麻疹病人接触史。结论白云区≤4岁麻疹病例表现出医院聚集性,存在院内感染的可能;≤4岁病例发病危险因素还可能与发病前3周内乘坐过交通工具及接触过麻疹现症病人有关。
Objective To study the risk factors of measles cases ≤4 years old in Baiyun District, Guangzhou City and to explore the countermeasures of measles prevention and treatment. Methods A total of 385 cases of measles cases ≤ 4 years old were collected from Baiyun District. The cases of illness, immunization history and related information were collected and analyzed with the questionnaire of measles cases. Results Measles vaccine (MV) inoculation history was 23.1% before 8 months to 4 years old, MV inoculation history was within 3 weeks before onset in 7.22% cases, MV in 3 weeks before onset of disease (30.13%) was the longest incubation period Visit history, 29.16% of cases before the onset of transport within 3 weeks of history, 6.23% of cases before the onset of measles patients within 3 weeks of exposure history. Conclusion Measles cases ≤ 4 years old in Baiyun District showed hospital agglomeration with the possibility of nosocomial infection. The risk factors of ≤4 years old patients may also be related to those who have been used to transport and have been exposed to measles in the previous 3 weeks.
