Several prospective methods for surveillance of influenza are systematically carried out among the population of this city: (a) monitoring of excess deaths from respiratory and other causes; (b) monitoring of excess absenteeism from work; (c) attempts to cultivate influenza virus from throat swabs obtained from patients with respiratory diseases attending outpatient services; (d) checking of increased antibody reactivity for prevailing influenza virus strains in serum samples obtained from healthy adults of the open population. The results of these studies will be reported with respect to influenza activity in the metropolitan area in the winter of 1976-1977. Comparison of the speed and effectiveness with which the influenza epidemic was identified in the urban population by the various surveillance methods will also be given.
(a) 监测呼吸道疾病及其他病因导致的超额死亡；(b) 监测工作缺勤率的异常升高；(c) 尝试从到门诊就诊的呼吸道疾病患者的咽拭子中培养流感病毒；(d) 检测从普通人群中健康成年人采集的血清样本中针对流行的流感病毒株的抗体反应性增强情况。这些研究结果将针对1976 - 1977年冬季大都市地区的流感活动进行报告。还将对通过各种监测方法在城市人群中识别流感疫情的速度和效果进行比较。
