Five Common myths about Legionella

Five Common myths about Legionella

Do you know Legionella fact from fiction? There are countless misunderstandings about this particular bacteria, so allow us to debunk some urban myths.

Myth: All Legionella bacteria is dangerous to humans

Myth1

 

To date, there are 58 different strains of Legionella bacteria, but fewer than half of them can cause illness in humans. Legionella pneumophila serogroup 1 is the specific strain which causes the most infections.

 

Myth: You can't be infected by drinking water

Myth2Legionella bacteria infiltrates the lungs when it is breathed in via airborne water droplets. In the majority of cases, this is in the form of steam or mist emitting from a shower, tap, air conditioning system, hot tub or similar environment. However, you can catch the bacteria by coughing or choking while drinking infected water. This aspirates the bacteria which can then enter the lungs.

 

Myth: Only old people are susceptible to Legionnaires' disease

Myth3While age is one of the risk factors for Legionnaires’ disease, with those over 45 deemed to be at greater risk, it is possible for any age to be infected. Those who smoke, have diabetes, immune deficiency or have a long-term lung disease such as asthma are at an even higher risk. Everyone could become ill under the right conditions.

 

Myth: You can catch Legionnaires’ disease by someone infected sneezing

Myth4

 

No, it is not contagious so it cannot be passed from person to person. The only way to contract Legionnaires’ Disease is by inhaling contaminated water droplets.

 

 

Myth: Legionnaires’ Disease is a big killer 

Myth5

Thankfully, it is not a big killer and can easily be treated in the majority of cases, if diagnosed early enough. However, the amount of cases of this disease in the United States are consistently rising, and it does become harder to treat if left undiagnosed. The best way to prevent Legionnaires’ is from the source itself: contaminated water.
