Legionnaire's disease Causes

Legionellosis is an infection that takes two distinct forms that include Legionnaire's disease and Pontiac fever. Both infections are caused by a bacterium known as:

  • Legionella Pneumophilia

The bacteria are found naturally and mostly thrive in water or moist places. It grows best in warm water and is commonly found in cooling towers, parts of air-conditioning systems, hot tubs, large plumbing systems and hot water tanks. Despite being a fatal disease that can cause the death of up to 30% of the infected people, healthy patients often recover from it. However, most cases are treated successfully using antibiotics and other home therapies.

Legionnaire's disease Diagnosis

To treat Legionnaire's disease, you need to be certain about its infection - therefore, you need a proper Legionnaire's disease diagnosis. A doctor may not prescribe medication based on signs and symptoms only, since they may be similar with those of other illnesses. A laboratory test is necessary to determine if there is an increase in the number of white blood cells used in fighting harmful things in the body. Mild abnormalities in the liver function may also suggest Legionnaire's disease infection. The doctor may also carry out a blood or/and urine test to check the presence of Legionnaire's bacteria. A chest X-ray may show abnormal densities where parts of the lungs in the X-ray film appear to be white.

Legionnaire's disease Treatment

There are various methods of treatment for Legionnaire's disease, but prevention is always better than cure. In most cases, doctors prescribe antibiotics that tend to be effective in treating legionellosis. Fluoroquinolones, macrolides and tetracyclines are the most commonly used antibiotics. Glycylcyclines are a new form of antibiotics introduced in the market and have shown to be effective as well. The choice of the type of antibiotic to use depends on the severity of the condition, patient's clinical taste and tolerance to the medication. In the case of severe Legionnaire's disease infection, doctors recommend the use of rifampin which is an addition drug to a previously used single tablet.
