According to the world’s foremost medical counsel to airlines, travellers are twice or even three times more likely to contract Covid-19 during a trip since the advent of the omicron version.
The new strain is highly transmissible and has quickly grown dominant, accounting for more than 70% of all new cases in the United States alone. Despite the fact that modern passenger jets have hospital-grade air filters, the danger of infection is significantly lower on flights than in busy places on the ground, such as shopping malls, omicron is fast spreading as more passengers take to the skies for year-end holidays and family reunions.
According to David Powell, a physician and medical adviser to the International Air Transport Association, which represents over 300 airlines worldwide, business class may be safer than more densely packed economy cabins. Passengers should avoid face-to-face contact and regularly touched surfaces, and persons sitting close to each other at meals should try not to be unmasked at the same time, he said.
What are the dangers of contracting an infection when flying?
We’d have to anticipate that whatever the risk was with delta, it’d be two to three times higher with omicron, as we’ve seen in other contexts. Whatever the low danger on the plane is – we don’t know – it must be increased by an equal amount.
What can travellers do to reduce their risks?
Prevent common-touch surfaces, hand hygiene whenever possible, masks, distance, controlled-boarding processes, avoid face-to-face contact with other customers, and avoid being unmasked in flight, except when absolutely essential. The advise remains the same; the relative risk has most likely increased, much like the relative risk of going to the shop or using the bus has increased with omicron.
What about using masks during mealtime?
‘Just keep your mask on the whole time,’ it’s simple to suggest on a two-hour flight. However, on a 10-hour flight, asking people not to eat or drink becomes absurd. Most airlines have been encouraging, but not requiring, customers to stagger their mask-off intervals.
In simple words, limited transmission occurs between two masked people. If one of you takes off your mask, that person is more likely to broadcast and somewhat more likely to receive. However, if you both eliminate the barrier, there is no longer any barrier, and you can freely transfer one to the other.
