Legionellosis is caused by different species of Legionella bacterial infection. What is this disease, what are the symptoms of Legionnaires ' disease and the mechanism of legionellosis. This infection is dangerous, and how can you protect yourself? All of these answers in this article.

In the U.S., in Philadelphia in 1976, among the participants and veterans of the Congress of the "American Legion", held at the modern hotel with air-conditioned, there is a strange infection. Of the almost 4.5 thousand people 221 of them suffered from a severe form of pneumonia and 34 of them failed with this disease to cope. Not known before the disease was called "Legionnaires ' disease", the causative agent of the pneumonia that was isolated from tissues of the dead from her people, was named "Legionella hemophilia". Later scientists have found similarities with other cases of infection that were caused by other species of Legionella, and all diseases that are caused by these microbes, has been called legionellosis.How is legionellosis?Legionellosis is caused by different species of Legionella bacterial infection. Scientists at the moment there are more than 40 types of the pathogen, 22 of which are for human risk.

Often doctors are dealing with the consequences from infection with Legionella hemophilia, which has the ability to allocate in the process of life and death of particular toxins. With the action of these toxins and the associated severe complications and symptoms.

Infected person source of infection is not, to others it is not dangerous. Legionella live in soil and freshwater bodies with standing water and blooming. Legionella, including inhabit and cooling systems, decorative fountains, swimming pools, even in hospitals situated in the ventilators and devices for balneological procedures. This organism lives almost anywhere where stagnant water, he water amoebas "friends," settled inside them and thus hiding from the bad effects of chlorine and other disinfectants.

Contamination by these organisms occurs occasionally inhalation of water vapour or water-dust aerosol. Most often, cases of legionellosis are recorded in people living long-term in hotels, in construction companies, who carry out excavation work. But pneumonia occur after treatment and physiotherapy.

In developed countries, suffering from legionellosis is much higher than in developing ones. These men get sick twice as often, outbreaks occur mainly in summer and autumn. For legionelleza pneumonia among all others is 5% and they are mostly severe, leading to complications and respiratory failure.

What is the disease regionalauthorities these state that legionellosis, in any form develops in 95% of infected, but in severe inflammation of the lungs it flows not at all. Pneumonia can be mild, but may develop alveolitis, and perhaps acute respiratory disease, for example fever or Pontiac, for example an acute febrile illness. But severe pneumonia this is a classic scenario of Legionnaires ' disease. Picture this pneumonia takes place 4-7 days after infection with Legionella.

Initially, the disease like the common cold flows: there are weakness, headache, appetite is getting worse, maybe an upset chair. Further, the body temperature rises to 40°C and there are signs of severe intoxication: sweats, chills, pain in the joints and muscles. The patient feels so weak that it is difficult to get out of bed.

After day 4 of the pneumonia reaches its peak, appears at first dry cough, then with a small amount of Muco-purulent sputum. On the background of inflammation of the pleura and lungs, causing severe chest pain and shortness of breath.

The defeat of the cardiovascular system toxins is reflected in the drop in blood pressure, pulse is rare and weak. 1/3 of patients complaining of rumbling and abdominal pain, diarrhea, possible development of jaundice or hepatitis.

From-for strong intoxications suffer from kidney and renal failure develops. Pneumonia occurs rapidly, treatment lends itself with difficulty and is frequently complicated by infectious-toxic shock, exudative pleurisy, lung abscesses, which lead to the deaths of patients.

If circumstances have developed successfully, and the patient has recovered, a long time will remain asthenic syndrome: fatigue, weakness, dizziness, frequent mood swings, irritability, loss of memory.

In medical institutions there is a strict accounting of cases legionellae pneumonia. In milder cases, the treatment happens in the home, insulation is not necessary since the Legionella from person to person not transmitted. For the same reason, in the room where the patient was, not produce final disinfection.
