| Most planes have something called a high-efficiency particulate air filter (Hepa).

| It's difficult to generalise about the risks on any form of transport because there are various factors that increase or decrease the risk. For example, on a long-haul flight passengers might move around more and, should they have the virus, risk spreading it further. | It's difficult to generalise about the risks on any form of transport because there are various factors that increase or decrease the risk.
