Pre-tests effectively reduce the incidence of contamination according to Delta

a A new study published in Mayo Clinic Proceedings, Georgia Department of Health and Delta Airlines analyze Passenger data On Delta flights with Covid testing before the flight between New York – JFK, Atlanta and Rome – Fiumicino. The risk of exposure to Covid-19 on a plane after all passengers tested negative 72 hours before flight appears to be less than 0.1%.

The study, published in Mayo Clinic Proceedings, shows that a single molecular test for COVID-19 done within 72 hours of departure can rate reduction Actively infected people on a commercial airliner Much lower than infection rates in the working population. For example, when the average local infection rate was 1.1%, Infection rates on the flights tested were 0.05%..

We will be living with different types of virus for a while. Governments can use this data in real life — and it’s not computed on simulation models,” says Dr. Henry Ting, Delta’s director of health.

According to the doctor, it can serve as a form for demanding vaccinations and tests. And Replacing quarries by reopening borders International travel.

Almost absolute safety in flight

Air travel risks vary by state and vaccination rates at departure and destination. But also mask wear and other factors. The data collected in this study show that regular use of a single molecular test 72 hours before travel for unvaccinated people significantly reduces the risk of exposure and transmission in aircraft.”

The study began in December 2020 with the COVID-19 testing program allowing entry without quarantine into Italy. The latter allowed teams to model different testing strategies. Especially with regard to feasibility, false positive rates, and case detection rates. The results of this study provide unique insight into the risks of exposure to the virus, infection rates on board, and establish a testing protocol.

Dr. added. Ting. ” These numbers will improve further with higher vaccination rates And that new cases are declining worldwide. “
