Governor Phil Murphy today announced the launch of a new COVID-19 exposure notification mobile app that will serve to supplement the state’s contact tracing efforts. 州长与纽约州州长安德鲁·科莫（Andrew Cuomo）合作宣布了这款应用程序，各州将加入包括宾夕法尼亚州和特拉华州在内的区域网络，以跟踪和警报暴露。 康涅狄格州也宣布将在不久的将来推出一款使用相同技术的应用程序。
The free mobile app – available to anyone 18 or older who lives, works, or attends college in New Jersey – is available for download from the Google Play Store or Apple App Store.
The apps use Exposure Notification System technology developed by Google and Apple to strengthen New Jersey and New York’s contact tracing programs statewide. The COVID Alert apps will notify users if they have been in close contact – within six feet for at least 10 minutes – with someone who has tested positive for COVID-19. 了解潜在的接触可以帮助个人快速制定保持安全的计划，包括联系他们的医生或州卫生部门的热线，以获取有关隔离和检测的更多信息，以防止社区传播。
COVID Alert NJ和COVID Alert NY是完全匿名的，不会从您的手机跟踪或收集任何位置数据或个人数据。 COVID警报应用程序不使用GPS位置数据。 暴露通知系统使用低功耗蓝牙技术来检测是否有另一部手机在六英尺范围内安装了同样的应用程序。 距离是可以衡量的，而不是地理位置。 COVID Alert app users must explicitly choose to turn on exposure notifications – and can turn it off at any time.
After downloading the app, users must opt-in to receive “Exposure Notifications.” When the app senses a close contact, your phone will exchange a secure random code with the close contact’s phone. 值得注意的是，您的位置、姓名或个人身份数据永远不会被披露。 If you test positive for COVID-19, a public health representative from the local health department will call as part of the states’ contact tracing programs and ask if you are willing to anonymously notify your “close contacts” by uploading your app’s anonymous close contact codes. 每天，该应用程序都会将您的密切接触者代码列表与COVID-19阳性应用程序用户相关的代码列表进行比较。 If there’s a match, you will get an Exposure Alert, along with appropriate next steps to stay safe and prevent community spread like self-quarantining and getting tested. COVID-19警报应用程序永远不会透露COVID-19阳性个体的身份。
新泽西州的COVID警报应用程序将与特拉华州、纽约州和宾夕法尼亚州的类似应用程序协同工作，使新泽西州的人在接触到这些州的居民时能够继续收到暴露通知。 如果新泽西州的居民前往其中一个州，并接触到有类似应用程序的COVID-19患者，该居民将收到通知。
COVID- Alert NJ和COVID- Alert NY为用户提供有关其所在州COVID-19的最新信息，包括公开报告的测试数据。 此外，该应用程序还具有症状检查器，用户可以匿名记录每日症状。
