The medical treatment for Legionella typically involves the use of antibiotics along with supportive care to manage symptoms. In addition to medical treatment, testing and validation play an essential role in the diagnosis and treatment of Legionella. The testing for Legionella involved with the detection of a bacterium in samples from the patient or the environment. Various testing methods are available, including culture-based methods, nucleic acid-based methods, as serology-based methods, the choice and testing method depends on the patient's symptoms, the level of risk and the type of sample being tested. Culture-based methods involve growing Legionella bacteria on a special culture medium. This method is time-consuming, it may take up to 10 days to obtain the results. Nucleic acid-based methods involve detecting the DNA or RNA of Legionella bacterium sample, this method is much faster and can provide results in a matter of hours. Serology-based methods involve detecting antibodies to Legionella bacteria in the patient's blood sample, this method can provide information on previous exposure to Legionella, but is not useful for the acute diagnosis of Legionella disease. Once the diagnosis of Legionella disease is confirmed, medical treatment can begin. Antibiotics of the primary treatment for Legionella disease, the choice of antibiotic depends on the severity of the patient's disease and the patient's medical history.

In severe cases, hospitalization may be necessary and supportive care may be required to manage symptoms such as fever, cough and a shortness of breath, after treatment is essential to validate the effects as a medical treatment and eradication of Legionella bacteria. Validation involves testing the environment to ensure that Legionella bacteria have been eliminated. The validation process includes the following steps: Sampling analysis, samples are taken from the water system and analysed to detect the presence of Legionella bacteria. The results are evaluated to determine whether the Legionella bacteria has been eliminated or whether further action is required. A risk assessment is carried out to identify new potential source of Legionella and assessed level of risk. And finally, an action plan is developed to address any potential sources of Legionella to ensure that the appropriate control measures are in place to prevent the growth and spread of the bacterium.
