Legionellosis , recognized as an sharp bacterial disease , whose etiological federal agent is Legionella bacterium , has two very well specify and dissimilar epidemiological and clinical bod : legionnaires disease ( legionnaires Pneumonia ) and Pontiac Fever ( Non - pneumonic Legionellosis ) .
Legionella metal money are omnipresent bacteria in natural environments and in unreal water reservoir . They proliferate in streams , river , lake , pool , mud , and filth . Until now , no less than 35 dissimilar species of Legionella have been identified . Legionella pneumophila is the species most ordinarily associated with the disease ; of this , 14 dissimilar serogroups have been key out . Among them , L. pneumophila serogroup 1 is the one that is usually connect with Legionellosis and other species different than Legionella , such as L. feelei and L. micdadei have been isolated in patients with resistant deficiencies and pneumonia .
Can You Get Legionnaires Disease From Drinking Water?
The ecology of Legionella ( which causes legionnaires disease ) in water system is not totally understood . However , studies argue that water at temperatures between 20 ºC and 45 ºC push the development of Legionella ( which causes legionnaires disease ) . The bacteria does not manifold below 20 ºC and does not survive at temperatures above 50 ºC. These organism can stay dormant and proliferate when temperature are adequate . The presence of deposit and organic matter can serve as a root of nutrients for this bacteria .
In places such as showers , faucets , steam boiler , heat exchangers and other sources of piss , Legionella bacterium can proliferate , due to the accumulation of deposit that usually come about as a result of the effect due to high temperature water . In addition , tube with little or no water , or those check mud and dirt , constitute a favorable surroundings for the growth and growth of L. pnemophila .
When the bacteria continue in stagnant weewee at a high temperature , such as in a kettle organisation , in a cooling pillar , or in a electrical condenser , it can easily reproduce and significantly increase the story of risk . If the contaminated piss comes into contact with our respiratory system , through consumption or via drops of piss suspended in the air , a life-threatening form of pneumonia can manifest itself ; also known as Legionnaires ’ Disease .
Individuals usually contract the legionnaires disease through the inhalation of contaminated water droplets . The symptom will take between two and ten days to seem . symptom that attest as headaches and muscle aches quickly turn over into external respiration difficulties and gastrointestinal irritation . The disease is similar to pneumonia , but more severe , so public agencies in all categories must pay off attending to the signs . Those organizations relate to the tourer sector , such as large recreational complex , tourism complex , leisure kernel and gymnasium where we can find sauna , jacuzzis or swimming pool should check and visit the equipment frequently .
Residences and hospitals are high - risk environments since most mortal are prostrate to infection due to their weak immune system and digest from underlying disease . Therefore , insure bacteria - loose water becomes the mellow anteriority .
drome , office buildings , and housing are other bacterial ontogenesis focus since they use expectant boiler systems and cooling towers to eradicate legionnaires disease .
Prevention of Legionnaires Disease
Since the designation of the etiological agent , legion nosocomial outbreaks of Legionnaires disease have been reported , which promotes the need to implement bar measure .
It is worth mentioning that the appearance of contaminant by Legionnaire disease in water distribution systems is relatively frequent . The heating of the pee and circulation through the net of the touched construction at temperature of 60 to 77 ° nose candy is the most effective disinfection organisation . The trouble is to get all item of the dispersion web to reach this temperature and the need to periodically repeat the process . The ventilation towers in which Legionella is detected should be disinfect according to existing protocols and then the effectualness of disinfection is controlled , which should lead to the remnant of the epidemic in 10 to 15 days .
Conclusion:
devote that governments act upon systematically to offer access to drinking water , it is easy to take it for granted . However , many citizenry are not aware that even booze water in appearance can entail dangers of legionnaires disease . The aforementioned preventive measure should be consider in club to nullify future outbreaks of the legionnaire disease .
