A total of 12 cases of Legionnaires' Disease have been reported to the CHP so far this year. 13 cases were reported in 2008, 11 in 2007 and 16 in 2006.
To prevent the disease, people are reminded to observe the following:
* An individual may reduce his/her susceptibility to the disease by avoiding smoking and excessive drinking, and maintaining good health.
* People handling garden soils, composts and potting mixes should take the following precautions:
- Gently water gardens and composts using low pressure.
- Open composted potting mixes slowly and make sure the opening is directed away from the face.
- Wet the soil to reduce dust when potting plants.
- Avoid working in poorly ventilated places such as enclosed greenhouses.
- Wash hands carefully afterwards.
* Proper design, operation and maintenance of man-made water systems.
For more information about the good practices to be followed in the design, installation, operation and maintenance of man-made water systems, please visit the website of the Electrical and Mechanical Services Department ( www.emsd.gov.hk/emsd/eng/pps/oa_ld_pub_cp.shtml ) for the Code of Practice published by the Prevention of Legionnaires' Disease Committee in 2007.
