Coronavirus Illness 2019 (COVID-19)


To supply a framework of concerns for ministries of well being and their companions to make use of whereas designing and implementing travel-related intervention methods. The suggestions are primarily based on individual-level danger evaluation of potential an infection of arriving vacationers to mitigate the geographic unfold of coronavirus illness 2019 (COVID-19).  This framework focuses on public well being measures to mitigate dangers of COVID-19 unfold amongst these crossing worldwide borders and for communities by way of which they journey; it serves as a dialogue information to start country-specific conversations for assessing danger of publicity and categorizing ranges of monitoring and motion to determine approaches commensurate with assets and insurance policies. This doc will not be meant for danger evaluation and administration of individuals touring into and inside america.


When outbreaks happen in areas with extremely cellular populations and porous borders, the chance of additional unfold inside an outbreak space or to different places with a connection to an outbreak space (e.g., neighboring nation, international locations with flight connections) is excessive. The advanced motion patterns in border communities and amongst cellular populations current challenges for figuring out contaminated or uncovered vacationers and facilitating acceptable public well being administration methods. Moreover, limitations in public well being surveillance at factors of entry contribute additional challenges.1

Recognizing that neighboring international locations could also be in numerous phases of the COVID-19 pandemic and have completely different methods for preparedness and response, it’s important that the excellent border well being measures international locations implement have “full respect for the dignity, human rights, and basic freedoms of individuals” [International Health Regulations, Article 3]2 whereas mitigating additional worldwide unfold.


The aims of this framework are to:

  • Describe strategies to evaluate the individual-level danger of COVID-19 publicity and potential an infection amongst cellular populations primarily based on signs, journey, publicity, and prognosis historical past
  • Describe acceptable risk-mitigation methods for cellular populations which are appropriate for nation assets
  • Present approaches to scale back danger of COVID-19 unfold in step with recognized individual-level danger evaluation outcomes and related risk-mitigation intervention ranges


This framework incorporates two components. Half 1 addresses the primary two aims and Half 2 addresses the third goal.  Earlier than initiating discussions associated to Components 1 and a couple of, ministries of well being and their companions ought to collect details about the nation’s authorized framework, together with authorized authorities for isolation* and quarantine** of nationals and non-nationals, regional steerage and authorized frameworks for border management measures, and out there assets for public well being interventions and communications.

Half 1

This framework describes strategies to assign a risk-mitigation intervention stage, e.g., none, minimal, intermediate, or excessive, primarily based on an individual-level danger evaluation. Matters on this half embrace making use of details about present signs in step with COVID-19, journey historical past of being in an outbreak space with ongoing neighborhood transmission, publicity historical past to suspected or confirmed instances, and prognosis historical past together with check outcomes.

Half 2

This framework options approaches to reply to the assigned risk-mitigation intervention stage, contemplating country-level assets. Approaches are ordered in scale of least to most restrictive and embrace a variety of approaches, together with no intervention, self-monitoring, monitoring by the well being authority, motion restrictions (together with voluntary or obligatory quarantine at a residence or a authorities approved-location) for asymptomatic individuals with recognized or potential publicity, to isolation (at a residence or in a healthcare facility) for symptomatic individuals with suspected or confirmed an infection. The number of acceptable approaches within the framework ought to be guided by public well being system capabilities and infrastructure and present outbreak standing. Approaches outlined on this part could also be integrated into present national-level steerage on contact tracing and monitoring of people who could have been uncovered to COVID-19.


Nations could not have established insurance policies or regulatory authority to impose obligatory quarantine or isolation, and should have various ranges of assets to dedicate to monitoring or proscribing motion of contaminated or uncovered people throughout preparedness and response phases. This doc doesn’t suggest the identical approaches for all international locations and serves as a dialogue information to start country-specific conversations. Ministry of well being discussions will inform refinements to the approaches used for monitoring and motion restrictions of uncovered individuals and individuals with suspected or confirmed an infection all through the pandemic.

*Isolation is the separation of individuals recognized or suspected to be contaminated with a communicable illness and doubtlessly infectious from those that are uninfected to stop unfold of the illness.

**Quarantine is the separation of these recognized or suspected to be uncovered to a communicable illness from those that are usually not uncovered for the aim of monitoring and to facilitate speedy isolation if they’re recognized as being contaminated.

Half 1: Assigning danger stage primarily based on individual-level danger evaluation

Utility: Public well being management can use the data under as a information for growing procedures for making use of details about individual-level danger, primarily based on journey or publicity historical past, presence of signs, and outcomes of any medical analysis or diagnostic testing, to establish the suitable risk-mitigation intervention stage. Danger ranges described under confer with the earlier 14 days.* After growing context-specific procedures, public well being management can use Half 2 to information concerns for mitigation technique approaches.

  • Decrease danger
  • Intermediate danger
    • Historical past of being in an space with ongoing neighborhood transmission**
      • Consideration: Particular person danger stage could range if the person absolutely practiced private protecting measures (e.g., social distancing; use of facemasks; handwashing; if traveler is a well being care employee, use of beneficial private protecting gear throughout affected person interactions)4,5,6
    • Historical past of attending a mass gathering or giant social gathering corresponding to a marriage
      • Consideration: Particular person stage danger stage could range if the person and different contributors absolutely practiced private protecting measures (e.g., social distancing; use of facemasks; handwashing)
    • Increased danger
      • An in depth contact7 of an individual with confirmed COVID-19,
        • Danger stage could be additional assessed by investigating whether or not the contaminated particular person and shut contact persistently wore face masks or took different beneficial precautions throughout publicity interval
        • Extra elements to think about when defining shut contact embrace proximity (nearer distance seemingly will increase publicity danger), period of publicity (longer publicity time seemingly will increase publicity danger), whether or not the contaminated particular person was symptomatic (the interval of onset of signs is related to the best stage of viral shedding), if the contaminated particular person was prone to generate respirator aerosols (e.g. by way of coughing, singing, shouting), and different environmental elements (e.g. crowding, adequacy of air flow, indoor or out of doors publicity)
      • Suspected or confirmed instances
        • Presence of indicators and signs in step with COVID-19 throughout journey or upon arrival
        • Optimistic RT-PCR or antigen check for SARS-CoV-2 earlier than departure or upon arrival and never assembly standards for discontinuation of isolation8,9

* Definitions of decrease and better danger actions on this doc differ from CDC steerage for U.S. settings.10

**WHO defines neighborhood transmission as: Nations/territories/areas experiencing giant outbreaks of native transmission outlined by way of an evaluation of things together with, however not restricted to: Giant numbers of instances not linkable to transmission chains. Giant variety of instances from sentinel lab surveillance or rising constructive instances by way of sentinel samples, a number of unrelated clusters in a number of areas of the nation/territory/space.11 Discuss with WHO ( icon) or nationwide information for contemporary outbreak info and affected areas.
