What is legionnaire decease?

You know, it's never been explained to my satisfaction. This was a while back, too. Mostly elderly war veterans, as well. I'd be interested in finding out what that was all about, myself. I have my suspicions but I'd like to hear hard core documented evidence.

Legionnaires' disease
A type of pneumonia usually caused by infection with the bacterium Legionella pneumophila, but occasionally with a related species (such as L. micdadei or L. dumoffii). The disease was first observed in an epidemic among those attending an American Legion convention in Philadelphia, Pennsylvania, in 1976. The initial symptoms are headache, fever, muscle aches, and a generalized feeling of discomfort. The fever rises rapidly, reaching 102–105°F (32–41°C), and is usually accompanied by cough, shortness of breath, and chest pains. Abdominal pain and diarrhea are often present. The mortality rate can be as high as 15% in untreated or improperly diagnosed cases. Erythromycin, new-generation fluroquinolones, and rifampicin are considered highly effective medications, whereas the penicillins and cephalosporins are ineffective.

While epidemics of Legionnaires' disease (also referred to as legionellosis) can often be traced to a common source (cooling tower, potable water, or hot tub), most cases seem to occur sporadically. It is estimated that Legionella spp. account for approximately 4% of all community- and hospital-acquired pneumonia. Legionnaires' disease is most fequently associated with persons of impaired immune status. Legionella bacteria are commonly found in fresh water and moist soils worldwide and are often spread to humans through inhalation of aerosols containing the bacteria. Legionnaires' disease is not a communicable disease, indicating that human infection is not part of the survival strategy of these bacteria. Therefore, the legionellae are considered opportunistic pathogens of humans. It is technology (air conditioning) and the ability to extend life through medical advances (such as transplantation and treatments for terminal diseases) that have brought these bacteria into proximity with a susceptible population.

For most humans exposed to L. pneumophila, infection is asymptomatic or short-lived. This is attributed to a potent cellular immune response in healthy individuals. Recovery from Legionnaires' disease often affords immunity against future infection. However, no vaccine exists at the present time. See also Medical bacteriology; Pneumonia.

What is Legionnaires’ disease?

Legionnaires’ disease (LEE-juh-nares) is caused by a type of bacteria called Legionella. The bacteria got its name in 1976, when many people who went to a Philadelphia convention of the American Legion suffered from an outbreak of this disease, a type of pneumonia (lung infection). Although this type of bacteria was around before1976, more illness from Legionnaires’ disease is being detected now. This is because we are now looking for this disease whenever a patient has pneumonia.

Each year, between 8,000 and 18,000 people are hospitalized with Legionnaires' disease in the U.S. However, many infections are not diagnosed or reported, so this number may be higher. More illness is usually found in the summer and early fall, but it can happen any time of year.

As stated above it is a respiratory disease caused by the pathogen ligionella. It was called Legionnaire's Disease because the first outbreak was at an American Legion convention. The symptoms had not been reported before, or weren't clearly understood. There was in this case a perfect vector for the organism to flourish. It lived in the HVAC system in the hotel. It was germinated in an outdoor "swamp cooler." This is an evaporative form of air conditioning used in places with low humidity. Water is cascaded over a series of coils. The evaporation cools the water and a heat exchanger delivers the cooled air through ducts. The pathogen lived in the dirty (unchanged) water and somehow got into the ducts and infected the guests in the hotel. New guidelines for this type of cooling plant have since been issued.

Legionnaires' Disease is recognized as an acute respiratory pneumonia caused by the aerobic gram-negative microorganism, Legionella pneumophila, and other species. This microorganism may also affect other body systems. Afflicted patients may have pulmonary (lung and bronchi), gastrointestinal tract, and central nervous system complications. Renal insufficiency may occur occasionally and can be severe enough to require dialysis.

Legionnaires' disease, which is also known as Legionellosis, is a form of pneumonia. It is often called Legionnaires' disease because the first known outbreak occurred in the Bellevue Stratford Hotel that was hosting a convention of the Pennsylvania Department of the American Legion. In that outbreak, approximately 221 people contracted this previously unknown type of bacterial pneumonia, and 34 people died. The source of the bacterium was found to be contaminated water used to cool the air in the hotel's air conditioning system.

Legionnaires' disease is most often contracted by inhaling mist from water sources such as whirlpool baths, showers, and cooling towers that are contaminated with Legionella bacteria. There is no evidence for person-to-person spread of the disease.

Symptoms of Legionnaires' disease include fever, chills, and a cough that may or may not produce sputum. Other symptoms include abdominal pain, diarrhea, and confusion. This list of symptoms, however, does not readily distinguish Legionnaires' disease from other types of pneumonia. Legionnaires' disease is confirmed by laboratory tests that detect the presence of the bacterium, Legionella pnuemophila, or the presence of other bacteria in the family Legionellaceae. It is the most often treated with the antibiotic drug Erythromycin.

Although Legionnaires' disease has a mortality rate of 5 to 15 percent, many people may be infected with the bacterium that causes the disease, yet not develop any symptoms. It is likely that many cases of Legionnaires' disease go undiagnosed.

Legionnaires' disease can be viewed as an example of how our physical environment affects our health. Relative humidity, temperature, and other environmental factors can alter the incidence and the fatality rates of infectious diseases, including Legionnaires' disease. For example, cooling towers and evaporative condensers of large air conditioning systems have been associated with outbreaks of the disease, and the highest incidence of Legionnaires' disease occurs in the warmest months of the year, the time when air conditioning systems are used the most.
