    Legionella.org, a non-profit organisation that provides information about the disease, explains, “You cannot contract Legionnaires’ disease from wearing face masks.”

    How can you get Legionnaires' disease?

    The NHS notes that you can catch Legionnaires' disease if you breathe in tiny droplets of water which contain bacteria that cause the infection.

    “It's usually caught in places like hotels, hospitals or offices where the bacteria have got into the water supply. It's very rare to catch it at home,” explains the NHS.

    When you start to get better you might be able to take antibiotic tablets at home, which usually last from one to three weeks.

    “Most people make a full recovery, but it might take a few weeks to feel back to normal,” notes the NHS.
