Countries could want to undertake totally different screening methods after a communicable illness has been launched and there’s sustained transmission in native communities. At that stage, entry screening could not be the perfect use of restricted human and different sources; traveler schooling and neighborhood mitigation methods (e.g., social distancing, closing faculties, canceling or suspending of mass gatherings) could also be extra helpful at slowing the illness’s unfold.

Opportunities for Health Officials to Communicate with the Traveling Public

Points of entry present necessary alternatives and venues for well being officers to speak with vacationers in regards to the danger of COVID-19 of their international locations and in different international locations, easy methods to defend themselves throughout journey, in addition to what to anticipate after journey, particularly if they’ve been in a rustic with lively neighborhood transmission of COVID-19.

Limitations of Public Health Screening at POE

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 following limitations of public well being screening at POE must be saved in thoughts:

  • Screening is simplest for detecting overtly unwell 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 attainable publicity (see third limitation beneath).
    • COVID-19 transmission from presymptomatic and asymptomatic contaminated individuals is understood to happen. This reduces the effectiveness of public well being screening at POE, significantly exit screening, as asymptomatic vacationers may infect co-passengers or others inside the POE itself.
  • Obtaining dependable temperature readings is affected by a number of elements, together with:
    • The ambient atmosphere wherein the temperature is measured. If the atmosphere is extraordinarily sizzling or chilly, physique temperature readings could also be affected, whatever the temperature-taking gadget that’s used.
    • Proper calibration of the thermometers per producer requirements. Improper calibration can result in incorrect temperature readings.
    • Proper utilization and studying of the thermometers.

Implementing COVID-19 Screening at a POE

These questions are supposed to information international locations via issues in regards to the capacities wanted to implement public well being screening at POE. CDC recommends that international locations don’t implement screening till they will reply “Yes” to all “Yes/No” questions and have mechanisms in place to answer suspected circumstances recognized at POE, together with for isolation or quarantine as much as 14 days.

Does the COUNTRY have:

    Secondary screeners ought to ideally have medical coaching (nurse or doctor).

    The variety of main screeners wanted could range by POE and the sources out there. Ideally, there must be two main screeners for each 60 vacationers per hour. Primary screeners ought to work in pairs, with one screener conducting visible statement and temperature checks, and the opposite asking questions or reviewing well being declaration varieties to acquire details about journey historical past, attainable exposures, and indicators and signs of sickness. Screening of every traveler ought to take lower than roughly 1 minute/individual, noting that almost all non-contact infrared thermometers require a relaxation interval of 15–60 seconds between temperature readings, relying on the model.

    One onsite secondary screener per shift at every POE is often sufficient.

  3. Adequate private protecting tools (PPE)2 and screening instruments (non- contact thermometers, batteries, well being declaration varieties, and so on.)?

Travelers who don’t want to be delayed, or who’re sick and don’t wish to be prevented from touring, could attempt to bypass POE screening.
  • Countries ought to consider their out there sources and take a risk-based method when figuring out which POE to pick out for public well being screening actions. Some elements to think about are:
    • The quantity of vacationers via the POE
    • Types 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 identified neighborhood
    • transmission of COVID-19
    • Whether circumstances have occurred close by and/or in closely populated areas
