对英格兰、威尔士和荷兰哨点全科医疗网络报告的 10 年来新发流感样疾病年龄的发病率数据进行了检查，以提供流感流行期间咨询人群的估计。每个年龄组的基线记录水平是根据流感病毒没有传播的周数计算的，并计算出超过基线的部分，以提供流感流行期间的人口估计数。甲型/H3N2流感流行与比乙型流感更高的就诊人口估计数相关，特别是在0-4岁和65岁及以上的年龄组中。在干预年龄组中，无论病毒类型如何，人口估计都更加一致。两个网络均报告所有年龄组的发病率同时达到峰值。流感流行期间报告其他呼吸道疾病的人数大幅增加。咨询人群的人口估计为估计流感流行期间卫生服务资源的利用提供了唯一可靠的基础。
Incidence data by age of new episodes of influenza-like illness reported by sentinel general practice networks in England and Wales and in The Netherlands over a 10-year period were examined to provide estimates of the consulting population during influenza epidemic periods. Baseline levels of recording in each age group were calculated from weeks in which influenza viruses were not circulating and the excess over baseline calculated to provide the population estimates during influenza epidemics.Influenza A/H3N2 epidemics were associated with higher population estimates for consultations than influenza B, especially in the age groups 0-4 and 65 years and over. In the intervening age groups, population estimates were more consistent regardless of the virus type. Both networks reported simultaneous peaking of incidence rates in all of the age groups. There were substantial increases in the number of persons reporting other respiratory illnesses during influenza epidemics.Population estimates of the consulting population provide the only secure basis for which health services resource utilization during influenza epidemics can be estimated.
