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.

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.
