What
is Legionnaires’ disease?
Legionnaires’ disease is a potentially fatal pneumonia
caused by legionella bacteria. It is the most well-known and serious
form of a group of diseases known as legionellosis. Other similar
(but usually less serious) conditions include Pontiac fever and Lockgoilhead
fever. At present over 42 different species are known.
Infection is caused by breathing in small droplets of water contaminated
by the bacteria. The disease cannot be passed from one person to
another.
Everyone is susceptible to infection but some people are at higher
risk e.g. those over 45 years of age, smokers and heavy drinkers,
those suffering from chronic respiratory or kidney disease, and
people whose immune system is impaired.
