Airports' Screening Methods For Coronavirus: Strategies And Technologies

Airports around the world have been screening passengers for coronavirus. This includes taking passengers' temperatures using hand-held scanners, assessing travellers for any signs of coughing or breathing difficulties, and asking passengers to fill in self-declaration forms. Screening is also an opportunity to give travellers guidance on what to do if they become ill and to gather contact information that could be useful if an infection did spread during a flight.

Temperature checks

Entry screening, done on arrival at the destination airport, can be an opportunity to gather contact information that is useful if it turns out an infection did spread during a flight. It is also a chance to give travellers guidance on what to do if they become ill. For example, passengers who don’t have any symptoms may be given cards at points of entry with instructions by health officials on what to do if a problem develops.

Exit screening can also be useful. China, for example, has pledged to "cooperate internationally to institute exit and entry screening with relevant regions suffering epidemics".

Coughing or breathing difficulties

Airports around the world have instituted point-of-entry and exit screening to prevent the spread of coronavirus. CDC employees will take the temperature of passengers using a hand-held scanner that doesn't touch the skin and assess travellers for any signs of coughing or breathing difficulties.

If a traveller is found to have a cough or breathing difficulties, they will be given instructions by health officials on what to do if a problem develops. This may include transportation, isolation, quarantine, contact tracing and outbreak management. The contact information gathered at the point of entry can be useful if it turns out an infection did spread during a flight.

In addition to screening, airlines have been directed to make in-flight announcements on flights coming from countries with a high number of coronavirus cases. These announcements will inform passengers of the screening process and instruct them to fill out a self-declaration form as per the instructions of the health and family welfare ministry.

Screening at airports is not always effective at preventing the spread of coronavirus. Retrospective studies have found that while screenings can be useful for slowing the spread of a virus, they do not always detect all cases. For example, in one instance of point-of-entry screening used to slow the spread of Ebola from western Africa in 2014, four cases were exported despite more than 300,000 passengers being screened.

Contact information

In addition, airlines have been directed to make in-flight announcements in flights coming from certain countries, and to ensure that self-declaration forms are filled out by passengers as per the instructions of the health and family welfare ministry.

Exit screening can also be used to gather contact information. For example, in 2014, more than 300,000 passengers were screened in three countries where the Ebola epidemic emerged. No cases were detected, yet four cases were exported.

Self-declaration forms

Airports around the world have been screening passengers for coronavirus. In some cases, this involves taking the temperature of passengers using a hand-held scanner and assessing travellers for any signs of coughing or breathing difficulties.

In other cases, passengers are given cards with instructions on what to do if they develop symptoms. These cards also serve as a way to gather contact information, which is useful if an infection spreads during a flight.

In India, passengers arriving from certain countries are required to fill out a self-declaration form as part of the screening process. This form is mandated by the health and family welfare ministry. Airlines are directed to make in-flight announcements on flights coming from these countries, informing passengers of the requirement to complete the form upon arrival.

The self-declaration form is usually distributed to passengers upon arrival at the airport. It can be completed electronically or on paper, depending on the airport's procedures. Passengers are typically required to provide their contact information, including their name, address, phone number, and email address. This information is essential for contact tracing efforts and allows health authorities to reach out to individuals if necessary.

In addition to contact information, the self-declaration form will ask passengers about their recent travel history. This includes questions about the countries they have visited, the dates of travel, and any potential exposure to the virus. Passengers may also be asked about their current health status, including any symptoms they are experiencing, such as fever, cough, or difficulty breathing. It is important for passengers to be honest and thorough in their responses to ensure the effectiveness of the screening process.

Completing the self-declaration form accurately and truthfully is a critical step in helping to prevent the spread of coronavirus. By providing health authorities with the necessary information, passengers can assist in early detection, contact tracing, and outbreak management. This allows for a more efficient and effective response to potential cases and helps protect the health and safety of the wider community.

Quarantine stations

At these stations, CDC employees take the temperature of passengers using a hand-held scanner that doesn't touch the skin and assess travellers for any signs of coughing or breathing difficulties. Passengers who are asymptomatic may be given cards with instructions on what to do if they develop symptoms. This can include information on how to access services such as transportation, isolation, quarantine, contact tracing and outbreak management.

In addition to the CDC's efforts, other countries have implemented their own screening measures. For example, India has directed airlines to make in-flight announcements on flights coming from specific countries, and the Mumbai airport has started screening passengers arriving from Malaysia, Indonesia, Vietnam, Nepal, China, Hong Kong, Singapore, Thailand and South Korea. Similarly, China has pledged to "cooperate internationally to institute exit and entry screening with relevant regions suffering epidemics".

Entry screening at airports can also be an opportunity to gather contact information that may be useful if an infection spreads during a flight. This information can be used to provide travellers with guidance on what to do if they become ill. While airport screening can help slow the spread of coronavirus, it is important to have additional strategies in place, such as public health services, to make screening truly effective and efficient.
