关于这个话题我们已经知道了什么？2020年2月27日，加州圣克拉拉县发现了首例与可能的社区传播相关的2019冠状病毒病（COVID-19）病例。这份报告补充了什么？在3月5日至14日期间，在圣克拉拉县作为哨点监测点的四个紧急护理中心之一评估的呼吸道症状患者中，23%的流感检测结果呈阳性。在流感检测结果为阴性的一部分患者中，11%的患者COVID-19检测结果为阳性。通过这一哨点监测系统发现的COVID-19病例有助于确认该县的社区传播。地方卫生部门可利用哨点监测了解COVID-19的社区传播水平，并更好地指导社区减缓措施的选择和实施。

Among a subset of patients with negative test results for influenza, 11% had positive test results for COVID-19.What are the implications for public health practice?COVID-19 cases identified through this sentinel surveillance system helped confirm community transmission in the county.
