1960年6月中旬,淄博专区乐陵县某厂职工,曾流行此病,作者在该处进行了流行病学初步调查及临床观察。由于集体发病规律酷似呼吸道急性传染病,临床表现为发热、哮喘;化验中血及骨髓象嗜酸性粒细胞明显增多,其中部分患者冷凝集试验阳性。经查阅本院文献,未见有类似报告。作者当时曾想到系一种新的传染病,可称为“传染性嗜酸性粒细胞增多症”,以便有剧于其它原因所致的嗜酸性粒细胞增多症,亦可与传染性单核细胞增多症及传染性淋巴细胞增多症相并列。现将调查资料及临床分析初步报导如下,对病原等问题提出初步探讨。一般调查该厂职工共314人,实际在厂工作者287人,发病者161人,发病率为56.1%。经调查以下几项关系如下:年龄:各年龄组发病率均甚高,彼此差剧不大(见表一)。似可说明,因系新的新传染病,在人群中易于传播,人群尚缺乏足够的免疫力。
In mid-June 1960, a factory in Ziling prefecture, Leling County, had a prevalent epidemic. The author conducted a preliminary epidemiological investigation and clinical observation there. As the collective disease resembles acute respiratory disease resembles the respiratory tract, clinical manifestations of fever, asthma; blood and bone marrow as eosinophils increased significantly, some patients with cold agglutination test was positive. After reviewing our literature, we did not find any similar reports. At that time, the author had thought of a new type of contagious disease called “infectious eosinophilia” in order to have eosinophilia caused by other causes and also with infectious mononuclear cells Increased disease and transmissible lymphocytosis phase side by side. The investigation data and the clinical analysis are as follows: The pathogens and other issues are discussed tentatively. The general survey of the plant a total of 314 workers, the actual factory workers 287 people, the incidence of 161 people, the incidence was 56.1%. The following are the investigation of the following relationships: Age: The incidence of each age group are very high, the difference between the drama is not (Table 1). It seems that because of the new infectious diseases, it is easy to spread in the crowd and the population lacks enough immunity.
