How COVID spreads on long-haul flights: A single passenger infected 15 people during a 10-hour journey to Vietnam



A new study published by the Centers for Disease Controls for Centers shows that during a 10-hour trip from London to Vietnam, a passenger was infected with the COVID-19 virus in 15 people.

The report shows how the 27-year-old unidentified woman spread the virus unknowingly in March. It shows how female travelers with sore throats before the flight infected 12 business class passengers, 2 economy class passengers and one crew member of the 217 passengers on board.

“Emerging Infectious Diseases” magazine reported: “She was sitting in the business class and continued to feel a sore throat and coughing throughout the flight.” A few days later, the 27-year-old business woman tested positive for the coronavirus.

According to official statistics, the number of deaths in the United States will reach 200,000 in the next few days, although the actual number will definitely be higher. The virus has infected more than 6.7 million Americans. According to the Washington Post, nearly 1

1,000 people have been exposed to the virus on airplanes.

The report added: “The most likely route of transmission during the flight is the spread of aerosols or droplets from Case 1, especially for business class passengers.

“During long-distance flights, the risk of spreading SARS-CoV-2 on board is real, and it may even cause the COVID-19 fleet to be large. Even in business class environments, its spacious seating arrangements are far beyond. The prescribed use distance defines close contact on the aircraft.”

The official guide on the CDC website states: “Air travel requires time spent on security lines and airport terminals, which may put you in close contact with other people and frequent ground contact.

Due to the way air is circulated and filtered on the plane, most viruses and other bacteria are not easily spread during flight.

“However, it is difficult to keep your distance from people on crowded flights. Sitting within 6 feet of others, sometimes up to several hours, may increase the risk of COVID-19.”

However, researchers from the National Institute of Hygiene and Epidemiology of Vietnam believe: “Although the international aviation industry has judged that the risk of in-flight transmission is very low, as many countries begin to cancel flights, especially long-distance flights have become increasingly worrying The problem. Although SARS-CoV-2 continues to spread, it is still restricted.

According to Forbes, the second study also investigated a cluster of four on a flight from Boston to Hong Kong in March.

In that case, the researchers wrote: “Based on the case history and sequencing results, the most likely event is that one or both of passengers A and B were infected with SARS-CoV-2 in North America, and The virus spread to flight attendants C and D in flight.

“The only place all four people approached for a long time was inside the aircraft.”

They added: “Our results strongly imply the airborne transmission of SARS-CoV-2. Our results show that SARS-CoV-2 can be transmitted on airplanes. In order to prevent the spread of the virus during travel, infection control must continue to be adopted. Measures.

In any case study, masks are not necessary.

According to multiple experts, the United States set a record for one day, with more than 1 million coronavirus diagnostic tests performed on Saturday, but the country needs 6 to 10 million cases a day to control the epidemic.

The virus continues to spread and there is currently no approved vaccine. Some public health experts worry that infections may surge this fall and winter, and the death toll may double by the end of the year.

However, the grim milestones and the prospect of more American deaths in the future did not prompt the president to reconsider how he responded to this pandemic, nor did he express regret externally.

Instead, Trump tried to reshape the importance of death records by arguing that without his government action, the number could be higher, thus making the lost 200,000 Americans a model of success.

According to data from the COVID Tracking Project, the country conducted 1,061,411 tests on Saturday, which is a work run by volunteers to track the epidemic. The record was obtained after a few weeks of decline in testing.

In the week ending September 13, the United States tested an average of 650,000 per day, and the peak at the end of July was 800,000 per day.

Since the beginning of the pandemic, insufficient testing has hindered efforts to contain the spread of the virus. At one point in the summer, Houston residents lined up in front of the car, waiting for hours to test, and even slept in the car all night. Miami has a similar performance.

Trump said in March, “Anyone who wants to take a test can take it.” That goal has not yet been achieved.

The Institute of Health Metrics and Evaluation at the University of Washington estimated in May that by October, about 180,000 people had died. Their forecast is currently about 378,000 deaths by January.
