TI  - Identification and Monitoring of International Travelers During the Initial Phase 
      of an Outbreak of COVID-19 - California, February 3-March 17, 2020.

AB  - The threat of introduction of coronavirus disease 2019 (COVID-19) into the United 
      States with the potential for community transmission prompted U.S. federal 
      officials in February 2020 to screen travelers from China, and later Iran, and 
      collect and transmit their demographic and contact information to states for 
      follow-up. During February 5-March 17, 2020, the California Department of Public 
      Health (CDPH) received and transmitted contact information for 11,574 
      international travelers to 51 of 61 local health jurisdictions at a cost of 1,694 
      hours of CDPH personnel time. If resources permitted, local health jurisdictions 
      contacted travelers, interviewed them, and oversaw 14 days of quarantine, 
      self-monitoring, or both, based on CDC risk assessment criteria for COVID-19. 
      Challenges encountered during follow-up included errors in the recording of 
      contact information and variation in the availability of resources in local 
      health jurisdictions to address the substantial workload. Among COVID-19 patients 
      reported to CDPH, three matched persons previously reported as travelers to CDPH. 
      Despite intensive effort, the traveler screening system did not effectively 
      prevent introduction of COVID-19 into California. Effectiveness of COVID-19 
      screening and monitoring in travelers to California was limited by incomplete 
      traveler information received by federal officials and transmitted to states, the 
      number of travelers needing follow-up, and the potential for presymptomatic and 
      asymptomatic transmission. More efficient methods of collecting and transmitting 
      passenger data, including electronic provision of flight manifests by airlines to 
      federal officials and flexible text-messaging tools, would help local health 
      jurisdictions reach out to all at-risk travelers quickly, thereby facilitating 
      timely testing, case identification, and contact investigations. State and local 
      health departments should weigh the resources needed to implement incoming 
      traveler monitoring against community mitigation activities, understanding that 
      the priorities of each might shift during the COVID-19 pandemic.
