疾病控制与预防中心宣布新型冠状病毒感染病例增加
疾病控制与预防中心（以下简称CDC）3月3日星期二中午报告，在12个州出现60例新型冠状病毒（COVID-19）病例。其中22例与旅行有关；11例被认为来自人际传播；其余27例的接触史尚在调查中。近日值得注意的动向包括：
报告出现病例的12个州是：亚利桑那州（Arizona），加利福尼亚州（California），佛罗里达州，佐治亚州，伊利诺伊州（Illinois），马萨诸塞州（Massachusetts），新罕布什尔州，纽约州，俄勒冈州（Oregon），罗得岛州，华盛顿州，以及威斯康星州（Wisconsin）。
随着新冠病毒继续扩散和美国检测能力增加，CDC预计全国将会发现更多病例，包括在更多州出现更多人际传播病例。虽然迄今的情况显示，大多数新冠病毒病症较轻，但来自中国的一项报告显示，重症比例为16%。年龄较大的人和有某些基础病——如心脏病，肺病和糖尿病的人，似乎有更大的重症风险。
联邦政府一直在与州、地方、部落和属地的合作伙伴以及公共健康合作伙伴密切共同努力，防备和应对这一公共健康紧急状况。CDC预计在未来数日和数周内将出现更多人际传播病例。
向CDC报告的病例包括得到CDC确诊的病例，也包括州所报告的推断阳性病例。推断阳性结果是指，由公共健康实验室检验出的结果呈阳性，但尚待得到CDC确诊。出于对公共健康的考虑，采用CDC检测方法得出的推断阳性结果被视为阳性病例对待。
CDC将在每个工作日的中午时间报告推断和确诊病例总数。这个数字是基于各州前一天下午4时前的报告。CDC不再报告正在接受调查的人数（PUI）以及调查结果呈阴性的人数，原因是，鉴于现在各州在检测和报告各自的结果，上述数字将不能反映全国的检测情况。各州的结果报告非常迅速，当CDC与州的病例统计数字出现差异时，应将州的统计结果视为最新数字。

At noon on Tuesday, March 3 the Centers for Disease Control and Prevention (CDC) reported 60 cases of COVID-19 from 12 states. Twenty-two of these cases are travel-related; 11 are believed to be person-to-person spread; and for the remaining 27 the source of exposure is still under investigation. Noteworthy developments in recent days include:
The 12 states that have reported cases include: Arizona, California, Florida, Georgia, Illinois, Massachusetts, New Hampshire, New York, Oregon, Rhode Island, Washington, and Wisconsin.
As the outbreak of COVID-19 continues to expand and as testing capacity in the U.S. increases, CDC expects more cases to be detected across the country, including more instances of person-to-person spread in more states. While information so far suggests that most COVID-19 illness is mild, a report out of China suggests serious illness occurs in 16% of cases. Older people and people with certain underlying health conditions like heart disease, lung disease and diabetes, for example, seem to be at greater risk of serious illness.
The federal government has been working closely with state, local, tribal, and territorial partners, as well as public health partners, to prepare for and respond to this public health emergency. CDC expects additional instances of person-to-person spread in the coming days and weeks.
Cases reported to CDC include those confirmed by CDC as well as presumptive positive cases reported by states. A presumptive positive result is when a patient has tested positive by a public health laboratory, but results are pending confirmation at CDC. For public health purposes, a presumptive positive result using the CDC test is treated as a positive.
CDC will report total presumptive and confirmed cases weekdays at noon. This number is based on all state reports received by 4 p.m. the previous day. CDC is no longer reporting number of persons-under-investigation (PUIs) nor those PUIs that test negative because now that states are testing and reporting their own results, these numbers would not be representative of the testing being done nationally. States are reporting results quickly and in the event of a discrepancy between CDC and state case counts, the state case counts should always be considered more up-to-date.
