At times we will not know how we will get affected by diseases as it is not easily predictable. If disease contaminate through medium like air and water, it is tough to control it as the level of contamination would be terribly high. You might have heard of the name legionnaires which will show dangerous signs of pneumonia and it is considered very much hazardous because it is caused by a bacteria.
Generally the bacteria which results in this disease can be sensed in water bodies and it is quite difficult to keep control of it when it is spread. It would be fine if you could avoid the spread of disease by maintaining the water bodies in a tidy manner from time to time. This disease can cause serious damage to the lung and so it is considered to be hazardous. Based on the severity of the spread of disease, the impact on your health will be accordingly. If the disease is caused due to bacteria, then it could be only avoided only if the micro-organisms are controlled. The root cause for the evolution of the spread of the disease have to be clearly understood and then action should be planned with respect to it.
As the need for the control of this disease had increased, safety management process like legionella risk assessment had become very much important. This way of taking necessary action to pause the harm caused by the bacteria legionella had been appreciated and thus it had been followed adversely. This type of risk assessment is very much required in UK as the disease impact is more in this place. There is an intense level of seriousness created in the minds of public in order to control the bacteria in water systems and so the Legionnaires disease risk assessment had been encouraged.
