Contracting infections inside public transport seem unbelievable but it’s possible.
The flu: Flu viruses can travel in the air via tiny droplets that get released when someone coughs, sneezes, or talks.
In public transport, because you are in close proximity with the other person when this person sneezes or coughs, you are more likely to catch the droplets.
According to Health.com, “Especially on a plane, the dry air from the altitude reduces our body’s natural immune defences, making it easier for the virus to enter the body.”
Is it possible to catch covid-19 in public transport? According to an article by the BBC, it depends on how crowded the bus or train is and the distance you can keep from other people.
A cynical virologist at the University of Leicester says that a key concern is sharing enclosed airspace because covid-19 particles linger in the air.
“If you are close enough to smell someone’s garlic breath on public transport, then you are also potentially inhaling any virus that’s carried with it.” Do ensure to wear a nose/face mask to lessen the risk.
Similarly to the flu, the common cold is caused by a few different viral strains that can also be transferred by air. “Many of these viruses remain active on surfaces like armrests, tray tables and seatback pockets for several hours, so washing your hands and disinfecting the surfaces around you can help reduce the spread,” notes Dr Agarwal.
Tuberculosis: While chances of picking it from a stranger on a public bus or train are unlikely, tuberculosis is caused by bacteria that spread from person to person through microscopic droplets released into the air.
This can happen when someone with the untreated, active form of tuberculosis coughs, speaks, sneezes, spits, laughs or sings.
Mayoclinic says that although tuberculosis is contagious, it’s not easy to catch. You’re much more likely to get tuberculosis from someone you live or work with than from a stranger.
Stop the spread: Wash your hands frequently and carry a sanitiser with you. Especially during the cold and flu season, do ensure to stay hydrated and get plenty of rest, which can give your immune system a boost according to Health.com.
