This doc is supposed to help Ministries of Well being and their point-of-entry (POE) companions in figuring out whether or not and tips on how to conduct traveler screening at POE for coronavirus (COVID-19).
The target of screening is to cut back the worldwide unfold of communicable illness by detecting departing vacationers who’re sick or who’ve been uncovered to the illness and stopping them from leaving the nation they’re in (exit screening) or by detecting them upon arrival and directing them to acceptable care and observe up, as wanted (entry screening).
Public well being screening happens in two levels:

Public well being screening at POE may be useful resource intensive, however it’s a versatile intervention that may be scaled up or down based on the wants of the nation and the standing of the outbreak. It can be crucial that nations repeatedly monitor the evolution of the pandemic globally, nationally, and regionally, and alter screening processes based on present wants.

International locations could want to undertake totally different screening methods after a communicable illness has been launched and there may be sustained transmission in native communities. At that stage, entry screening could not be the most effective use of restricted human and different assets; traveler training and neighborhood mitigation methods (e.g., social distancing, closing colleges, canceling or suspending of mass gatherings) could also be extra useful at slowing the illness’s unfold.
The sections beneath present steering on the next:
- How and what to speak with vacationers about COVID-19
- Limitations of POE screening
- Guidelines for nations to know if they’ve the capability to implement public well being screening at POE
- Extra concerns for nations contemplating implementing screening at floor crossings or delivery ports
Factors of entry present vital alternatives and venues for well being officers to speak with vacationers concerning the danger of COVID-19 of their nations and in different nations, tips on how to shield themselves throughout journey, in addition to what to anticipate after journey, particularly if they’ve been in a rustic with energetic neighborhood transmission of COVID-19.
The next are some advisable communication methods for nations to contemplate creating along with, or other than, different public well being measures instituted at POE.
Key data to share with vacationers consists of:
- Signs of COVID-19
- Learn how to self-monitor for sickness and what to do if signs develop
- Public well being measures in place at departure and vacation spot POE
- Learn how to put together for upcoming worldwide journey, together with:
- Measures to remain wholesome and cut back the danger of an infection throughout journey
- Suggestions to recurrently test data posted on official authorities web sites of the vacation spot nation to seek out out about:
- Presence of ongoing neighborhood transmission of COVID-19
- Screening and regulatory measures (i.e., isolation, quarantine) in place
- Availability of healthcare providers at their vacation spot
- Screening and regulatory measures they need to anticipate upon return to their nation of origin.
Strategies of communication for journey associated messaging embrace:
- Distributing Journey Well being Alert Notices (T-HAN) – a paper handout given to arriving or departing vacationers containing details about COVID-19
- Displaying well being messages the place most worldwide vacationers enter or depart the POE.
- Creating audio or video messages for airways to broadcast throughout flights with details about COVID-19 and public well being measures which were employed on the vacation spot POE.
- Disseminating messages, e.g., by social media
Public well being screening at POE is topic to a number of limitations and must be supplemented with enhanced neighborhood surveillance and different public well being measures.1
The next limitations of public well being screening at POE must be saved in thoughts:
- Screening is only for detecting overtly in poor health vacationers; vacationers who’re contaminated, however not exhibiting indicators of sickness (e.g., presymptomatic or asymptomatic) could also be missed throughout screening at POE, particularly if they don’t self-report a doable publicity (see third limitation beneath).
- COVID-19 transmission from presymptomatic and asymptomatic contaminated individuals is thought to happen. This reduces the effectiveness of public well being screening at POE, notably exit screening, as asymptomatic vacationers might infect co-passengers or others throughout the POE itself.
- Acquiring dependable temperature readings is affected by a number of elements, together with:
- The ambient atmosphere through which the temperature is measured. If the atmosphere is extraordinarily scorching or chilly, physique temperature readings could also be affected, whatever the temperature-taking system that’s used.
- Correct calibration of the thermometers per producer requirements. Improper calibration can result in incorrect temperature readings.
- Correct utilization and studying of the thermometers. Non-contact infrared thermometers ceaselessly used for well being screening should be held at a sure distance from the temporal artery within the brow to take the temperature appropriately. Holding the system too removed from or too near the temporal artery impacts the studying.
- Screening depends on vacationers behaving in a way which will battle with their instant private curiosity. To stop disruptions to their journey, people could not reveal details about their signs or publicity historical past or attempt to disguise signs by taking remedy.
These questions are supposed to information nations by concerns concerning the capacities wanted to implement public well being screening at POE. CDC recommends that nations don’t implement screening till they’ll reply “Sure” to all “Sure/No” questions and have mechanisms in place to reply to suspected circumstances recognized at POE, together with for isolation or quarantine as much as 14 days.

Extra concerns for nations contemplating implementing screening at floor crossings or delivery ports
- In contrast to airports, which have the established infrastructure, assets, and skill to funnel vacationers by managed pathways to implement screening compliance, floor crossings and delivery ports typically lack the infrastructure and assets to successfully perform screening in a scientific method.
- Screening at floor crossings slows journey and may be simple to bypass by taking a detour across the screening level, resulting in vacationers crossing alongside unstaffed sections of the border. Vacationers who don’t want to be delayed, or who’re sick and don’t need to be prevented from touring, could attempt to bypass POE screening.
- International locations ought to consider their out there assets and take a risk-based strategy when figuring out which POE to pick out for public well being screening actions. Some elements to contemplate are:
- The amount of vacationers by the POE
- Forms of vacationers (demographic data, the place they’re coming from/going to/stopping at, function of journey)
- The POE’s connectivity to geographic areas with recognized neighborhood
- transmission of COVID-19
- Whether or not circumstances have occurred close by and/or in closely populated areas
- Screening feasibility (Is there a approach to direct vacationers by the screening course of? Can screening employees simply entry the designated location? Can in poor health vacationers be remoted safely on the POE and transported to a referral healthcare facility?)
- Screening ought to solely be carried out at POE the place the protection and safety, of each vacationers and screening personnel may be assured (e.g., screening shouldn’t be situated in areas weak to violence or exterior areas missing shade or safety from the weather).
