The fatality rate of Legionnaires' disease has ranged from 5–30% during various outbreaks and approaches 50% for nosocomial infections, especially when treatment with antibiotics is delayed. [38] Hospital-acquired Legionella pneumonia has a fatality rate of 28%, and the principal source of infection in such cases is the drinking-water ...
This is a list of Legionnaires' disease outbreaks; Legionnaire's is a potentially fatal infectious disease caused by gram negative, aerobic bacteria belonging to the genus Legionella. [ 1 ] [ 2 ] The first reported outbreak was in Philadelphia, Pennsylvania in 1976 during a Legionnaires Convention at the Bellevue-Stratford Hotel .
Legionella can be used as a weapon, and indeed genetic modification of L. pneumophila has been shown where the mortality rate in infected animals can be increased to nearly 100%. [58] [59] [60] A former Soviet bioengineer, Sergei Popov, stated in 2000 that his team experimented with genetically enhanced bioweapons, including Legionella. [60]
Around 10% of people who contract Legionnaires’ disease will die from those complications — and the mortality risk rises to 25% for those who get Legionnaires’ while staying in a health care ...
According to the CDC, Legionella bacteria can cause a serious type of pneumonia, known as Legionnaires disease or Pontiac fever. Legionella bacteria is spread through the air when an individual ...
Legionella pneumophila is the most common cause, but sometimes other species of Legionella bacteria also cause Legionnaires' disease. [ 15 ] [ 16 ] The terms "Philadelphia fever" and "Legion fever" appear to have been used at the time of the outbreak and for shortly thereafter, [ 17 ] although at least one 2008 source which covers disease in a ...
The legionella bacteria responsible for the disease lives and multiplies in water areas like hot tubs, air conditioners, mist sprayers in grocery store produce departments, and water systems.
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
