An outbreak of the SARS-CoV-2 virus was suspected among passengers on a flight recently, and researchers in China retrospectively investigated this claim.

According to a study published on July 6, 2020, there appears to have been a limited transmission of coronavirus to just 1 person while onboard the flight, based on the epidemiological findings.

This review of 16 COVID-19 disease patients was diagnosed among all passengers, which indicates the overall virus attack rate was 4.8 percent.

The attack rate among passengers who had departed from Wuhan, China, was significantly higher than that among those who had departed from other places. 

One passenger, without an epidemiological history of exposure before boarding the flight, developed COVID-19. 

During the flight, he was seated near 4 infected passengers from Wuhan for approximately 1-hour and did not correctly wear his facemask during the flight.

These researchers concluded this study stating ‘COVID-19 transmission may have occurred during the flight.’

‘However, the majority of the cases in the flight-associated outbreak could not be attributed to transmission on the flight, but were associated with exposure to the virus in Wuhan or to infected members in a single tour group.’

This finding supports the assumption that most viruses and other germs do not spread easily on flights because of how air circulates and is filtered on airplanes. 

A previous incident during April 2020 disclosed similar results. This report identified a case of COVID-19 that was most likely acquired during a flight from the Central African Republic to Paris, France.

To alert international travelers of their health risk, the US Centers for Disease Control and Prevention issued a global advisory on June 5, 2020.

This Level 3 Travel Alert stated: ‘Widespread ongoing transmission of a respiratory illness caused by the novel coronavirus (COVID-19) is occurring globally.’

Furthermore, ‘the CDC recommends that travelers avoid all nonessential international travel.’

If travel is necessary, the CDC suggests various travel vaccinations, prior to departing abroad.
