流感和流感样疾病（ILI）的监测对于指导公共卫生预防计划以降低流感（包括大流行性流感）引起的发病率和死亡率非常重要。流感和ILI监测的非传统数据来源如果能够确定其有效性，则会引起公共卫生当局的兴趣。通过自动化手段收集全国电话分诊呼叫数据，用于症状监测。对于至少有500，000名居民有资格使用电话分诊服务的17个州，将呼吸道综合征的呼叫量与疾病预防控制中心每周流感分离株数量和ILI定点提供者就诊百分比进行比较。呼叫数据与CDC病毒分离株或哨兵提供者ILI百分比数据相关的程度在各州之间差异很大。在美国，电话分诊数据的覆盖范围是不完整的，因此在全国范围内不是ILI监测数据的可靠来源。然而，在呼叫数据和CDC数据之间显示出更高相关性的州，呼叫数据可以用作州一级监测数据的辅助，例如在哨点监测未运行时或在哨点提供者覆盖被认为不足的地区。足够的人群覆盖率，特定的ILI综合征定义，以及使用ILI呼叫百分比阈值可能会提高此类数据用于ILI监测目的的实用性。
Surveillance for influenza and influenza-like illness (ILI) is important for guiding public health prevention programs to mitigate the morbidity and mortality caused by influenza, including pandemic influenza. Nontraditional sources of data for influenza and ILI surveillance are of interest to public health authorities if their validity can be established. National telephone triage call data were collected through automated means for purposes of syndromic surveillance. For the 17 states with at least 500,000 inhabitants eligible to use the telephone triage services, call volume for respiratory syndrome was compared to CDC weekly number of influenza isolates and percentage of visits to sentinel providers for ILI. The degree to which the call data were correlated with either CDC viral isolates or sentinel provider percentage ILI data was highly variable among states. Telephone triage data in the U.S. are patchy in coverage and therefore not a reliable source of ILI surveillance data on a national scale. However, in states displaying a higher correlation between the call data and the CDC data, call data may be useful as an adjunct to state-level surveillance data, for example at times when sentinel surveillance is not in operation or in areas where sentinel provider coverage is considered insufficient. Sufficient population coverage, a specific ILI syndrome definition, and the use of a threshold of percentage of calls that are for ILI would likely improve the utility of such data for ILI surveillance purposes.
