北领地（NT）疾病控制中心（CDC）对NT内所有2019冠状病毒病（COVID-19）报告病例进行了接触者追踪。于二零二零年三月一日至四月三十日期间，新界共呈报28宗COVID-19病例。在同一时期，共有527人被确定为剂量接触者; 493人成功接触; 445人位于NT，随后在与确诊的COVID-19病例接触后每天隔离并监测疾病症状14天。在这445名剂量接触者中，4名在出现症状后检测出COVID-19阳性; 2/46名接触者是游轮乘客（4.3%，95% CI 0.5-14.8%）和2/51名家庭接触者（3.9%，95% CI 0.5-13.5%）。在新界接受监测的326名飞机乘客或4名医务工作者中，没有一人因剂量接触而成为病例。
The Northern Territory (NT) Centre for Disease Control (CDC) undertook contact tracing of all notified cases of coronavirus disease 2019 (COVID-19) within the NT. There were 28 cases of COVID-19 notified in the NT between 1 March and 30 April 2020. In total 527 people were identified as dose contacts over the same period; 493 were successfully contacted; 445 were located in the NT and were subsequently quarantined and monitored for disease symptoms daily for 14 days after contact with a confirmed COVID-19 case. Of these 445 dose contacts, 4 tested positive for COVID-19 after developing symptoms; 2/46 contacts who were cruise ship passengers (4.3%, 95% CI 0.5-14.8%) and 2/51 household contacts (3.9%, 95% CI 0.5-13.5%). None of the 326 aircraft passengers or 4 healthcare workers who were being monitored in the NT as dose contacts became cases.
