SGS Test now to Avoid Legionnaires Disease Outbreak
Legionaries’ Disease (LD)
The recent infection of LD by the education chief Michael Suen Ming-yeung, and the discovery of Legionella bacteria in water samples from the New Government office and the Legislative Council complex have raised public concern over this disease.
LD is an infectious disease that primarily affects the elderly, smokers and patients with Chronic Diseases. It is caused by the bacteria Legionella. The inhalation of the Legionella-contaminated aerosols can then lead to the infection of this disease. There are over 40 species of Legionella identified, and most of the infections are caused by a specific type known as serogroup 1.
