“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 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 shows that vaccination protects travelers from serious illness and death, and carries a low risk of introducing the virus into destination countries:
- The Robert Koch Institute (RKI) concluded that vaccinated travelers are no longer significant in the spread of the disease and do not pose a major risk to the German population.
- The European Centre for Disease Control and Prevention (ECDC) issued interim guidance on the benefits of full vaccination stating that “the likelihood of an infected vaccinated person transmitting the disease is currently assessed to be very low to low.”
- The US Centers for Disease Control and Prevention (US CDC) stated that “with a 90% effective vaccine, pre-travel testing, post-travel testing, and 7-day self-quarantine provide minimal additional benefit.”
- The Canadian Testing and Screening Expert Advisory Panel recommends that vaccinated travelers do not need to be quarantined.
- A Public Health England study has concluded that two doses of the COVID-19 vaccines are highly effective against COVID-19 variants of concern.
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.
- Between 25 February and 5 May 2021, 365,895 tests were conducted on arriving passengers to the UK. These were PCR negative before travel. Only 2.2% tested positive for COVID-19 infection during universal quarantine measures after their arrival. Of these, over half were from “red list” countries, which were considered very high risk. Removing them from the statistics would result in test positivity of 1.46%.
- Of the 103,473 arrivals from the EU (excluding Ireland), 1.35% tested positive. Three countries, Bulgaria, Poland and Romania, accounted for 60% of the positive cases.
“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.
Airbus Modeled Whole Journey Risk
Focusing on risks across the whole journey, Airbus considered more than 50 variables in its model. Assumptions for the model are based on over a dozen data sources and results were cross referenced against data collections from actual results and observations from travel. Findings include:
- High to medium incidence - Latin America & Caribbean (292 cases/100,000 population) to Canada (95 cases/100,000 population): Assuming the same traffic as in 2019 and without any testing, we expect that the local incidence in Canada would increase by just over 1 case / 100,000 population due to the imported cases over 14 days. With a single PCR test before travel, this number falls to less than 1 case/100,000 population.
- Medium to medium incidence - Europe (111 cases/100,000 population) to US (81 cases/100,000 population): Assuming the same traffic as in pre-COVID-19 and without any testing, the Airbus model predicts that air travel over 14 days would add less than 1 imported case/100,000 population to the local incidence in the United States.
- Medium to low incidence - Europe (111 cases of COVID-19/100,000 population) to Singapore (8 cases/100,000 population): Conservatively assuming the same traffic as in 2019 and without any testing, we predict that over 14 days air travel would add over 1 imported case/100,000 population to the local incidence in Singapore. With a PCR test before travel, this number falls to less than 1.
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 modeling revealed several key findings:
- Data show there are screening protocols as effective as a 14-day quarantine
- Screening protocols lower the risk to the destination country
- Screening is most beneficial for travel from higher to lower prevalence areas.
“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.
