IATA: From Data to Travel Freedom
Geneva - The International Air Transport Association (IATA) urged governments to make data-driven decisions to manage the risks of COVID-19 when reopening borders to international travel. Strategies without quarantine measures can enable international travel to restart with a low risk of introduction of COVID-19 to the travel destination.
“Data can and should drive policies on restarting global travel that manage COVID-19 risks to protect populations, revive livelihoods and boost economies. We call on the G7 governments meeting later this month to agree on the use of data to safely plan and coordinate the return of the freedom to travel which is so important to people, livelihoods and businesses,” said Willie Walsh, IATA’s Director General.
Evidence continues to show that vaccination protects travelers from serious illness and death, and carries a low risk of introducing the virus into destination countries:
Testing for Unvaccinated Travelers
A challenge is the potential of barriers to travel for unvaccinated people which would create an unacceptable exclusion. Data from the UK NHS regarding international travelers arriving in the UK (with no reference to vaccination status) shows that the vast majority of travelers pose no risk for the introduction of COVID-19 cases after arrival.
“Many governments continue to require universal quarantine—either hotel-managed or self-managed. This impedes the freedom of movement, discourages international travel and destroys employment in the travel and tourism sector. Data from the UK tells us that we can and must do better. Almost 98% of those detained because of universal quarantine measures tested negative for the virus. We now have more than a year of global data that can help governments make more targeted decisions on international travel. This can keep the risk of importing COVID-19 cases low—including variants of concern—while restarting international travel with minimal infringement on the ability to live normal work and social lives. Importantly, lives that include travel,” said Walsh.
IATA teamed-up with Airbus and Boeing to demonstrate potential methodologies to manage the risks of COVID-19 to keep populations safe while restarting global connectivity. Aviation, including manufacturers, effectively manages and mitigates risk every day to keep air travel safe. Using these skills, Airbus and Boeing have developed data-driven risk-management models to understand the impact of various options.
Airbus Modeled Whole Journey Risk
Focusing on risks across the whole journey, Airbus considered more than 50 variables (such as number of confirmed cases and fatalities per country, COVID-19 testing strategies, traffic statistics, flight length, time spent in airport terminals, provision of on-board catering and air conditioning) in its model. Assumptions for the model are based on over a dozen data sources (including US CDC and the World Health Organization). And results of the model were cross referenced against data collections from actual results and observations from travel. Using current COVID-19 incidence data and not making any consideration for vaccinated travelers (which would only lower the risk of infections), example findings include:
The Airbus model—designed to support government stakeholders to reopen air travel—demonstrates that the risk of virus transmission and translocation can be significantly reduced by adopting data-driven screening and protection measures.
Boeing Modeled the Efficacy of Testing Strategies
Boeing modeling and analysis shows screening protocols offer an alternative to mandatory quarantines for many travel scenarios. The model evaluates the effectiveness of passenger screenings and quarantines in countries around the world. It accounts for various factors including COVID-19 prevalence rates between origin and destination countries, the efficacy of PCR and rapid antigen tests, and the disease timeline (how the disease progresses) for passengers traveling with COVID-19.
The modeling revealed several key findings:
The passenger screening model and findings were validated using actual travel testing data from Iceland and Canada. Boeing is now modeling scenarios with vaccinated travelers. As data on new COVID-19 variants becomes available, it will also be incorporated in the model.
“There is no one-size-fits-all solution to manage the various levels of risk. The economic and social cost of the blanket measures taken by most governments to date has been unnecessarily high. With this modeling, we are demonstrating that we can be smart with calibrated travel policies that address the risks, enable travel, and protect people. Everybody can respect a data-driven decision. That is the way back to normality,” said Walsh.
No single government action can drive a recovery for international travel. The G20 Tourism Ministers endorsed a data-driven approach to reopening borders. The aviation industry is encouraging the G7 to take leadership by agreeing to work together to use the enormous amounts of data collected since the start of COVID-19 to drive a recovery effort. Critically that must restore the freedom to travel for tested or vaccinated persons while avoiding quarantine measures for the vast majority of travelers.
Cooperation to Protect the Healthcare System
Industry risk-management expertise can help the public health sector manage a return toward normality.
“COVID-19 is something that we need to learn to manage, like we do other risks to health. We accept many things in society that we know come with risks—from consuming alcoholic beverages to how we drive. We don’t ban these activities. We have some common-sense rules and the information needed to make sensible decisions about how to manage these risks. The post-pandemic future means doing the same for COVID-19 so we can all get on with our lives. There is no completely risk-free protocol. Vaccination will play a big role. And the data we have tells us that screening and testing protocols can make travel safely accessible for all,” said Walsh.
“Government policies are naturally risk averse. By contrast, the private sector has great experience in managing risks every day to deliver its products and services. COVID-19 now appears to be becoming endemic. This means that COVID-19 is not likely to disappear anytime soon, so governments and industry must work together to rebuild global connectivity while managing the associated risks. The first step is for governments to evaluate the threshold of risk of virus introduction that they can effectively manage. Then they need to identify with industry feasible strategies to enable an increase in international travel without exceeding those thresholds. Airbus, Boeing and IATA have demonstrated some possible solutions. Now we need more intense and transparent dialogue between governments and the airline industry to move from models to policy and ultimately facilitate international travel,” said Professor David Heymann of the London School of Hygiene and Tropical Medicine.
