A new study simulated the transmission of SARS-CoV-2, the virus
that causes COVID-19, on a flight from London to Hanoi and on
another flight from Singapore to Hangzhou.



FULL STORY ==========================================================================
A study published in Indoor Air simulated the transmission of SARS-CoV-2,
the virus that causes COVID-19, on a flight from London to Hanoi and on
another flight from Singapore to Hangzhou.


==========================================================================
When simulating the dispersion of droplets of different sizes generated
by coughing, talking, and breathing activities in an airline cabin by an infected person, researchers found that SARS-CoV-2 virus contained in
such droplets traveled with the cabin air distribution and was inhaled
by other passengers.

The scientists counted the number of viral copies inhaled by each
passenger to determine infection. Their method correctly predicted 84%
of the infected/ uninfected cases on the first flight. The team also
found that wearing masks and reducing conversation frequency between
passengers could help to reduce the risk of exposure on the second flight.

"We are very pleased to see that our model validated by
experimental data can achieve such a high accuracy in predicting
COVID-19 transmission in airliner cabins," said corresponding
author Dayi Lai, PhD, Associate Professor and Associate Head
of the Department of Architecture, School of Design of Shanghai
Jiao Tong University, in China. "Also, it's important to know that
wearing masks makes a significant impact on reducing the transmission." ========================================================================== Story Source: Materials provided by Wiley. Note: Content may be edited
