02 Legionnaires' Disease


Over 16 species of the genus Legionella have been shown to be associated with respiratory tract infections in Man. The term legionellosis is given to the disease caused by these micro-organisms. The severity of the disease ranges from Legionnaires’ disease, an acute severe pneumonia with low attack rate and relatively high death rate, to Pontiac fever, a mild non-pneumonic, flu-like infection with high attack rate but no fatalities. It would be noted that

L. pneumophila serogroup 1 is the most common cause of human infection.
