Legionnaires’ Disease – Causes, Symptoms, and Treatments
Whether you are new to Legionnaires’ Disease or you have had it for a while, it is important to learn about the disease’s causes, symptoms, and treatments. There is no cure for the disease, but you can prevent it by following a few important guidelines.
Symptoms
Symptoms of Legionnaires’ disease include coughing, shortness of breath, high temperature, and muscle aches. Symptoms may also include abdominal pain, joint pain, confusion, headache, and nausea.
Legionnaires’ disease is caused by a type of bacteria called Legionella. These bacteria can be found in many places in the environment, such as in ponds, lakes, and hot water taps.
People with weakened immune systems are more susceptible to Legionnaires’ disease. They may be living in long-term care facilities, have recently had surgery, or have taken medications that weaken their immune system.
Legionnaires’ disease symptoms usually develop two to 10 days after a person is exposed to the bacteria. In severe cases, it can lead to respiratory failure, kidney failure, and multi-organ failure. These complications may occur if the disease is not treated early.
The symptoms of Legionnaires’ disease may also include high blood pressure, fever, chills, muscle aches, diarrhea, and headache. It may also cause low blood sodium levels.
If Legionnaires’ disease is diagnosed early, most patients can recover completely. However, it can be fatal if not treated in a timely manner. It can be diagnosed by a doctor, who may recommend a chest X-ray. The X-ray may show fluid accumulation around the lungs. Other tests, such as a sputum culture, may be performed to help identify the source of the infection.
Legionella pneumonia is similar to other forms of pneumonia. The most common organ affected is the liver, though the spinal cord, spleen, and lymph nodes are also affected.
Legionnaires’ disease may be fatal if not treated in a prompt manner. It can also cause septic shock, which occurs when a person’s blood pressure drops too low.
Cause
Previously known as Legion Malady, Legionnaires’ disease is a life-threatening form of pneumonia. It is caused by breathing in Legionella bacteria that are dispersed in contaminated water. The bacteria multiply inside a white blood cell called a phagocyte. The phagocyte is a cellular immune system representative that clears air spaces of infectious particles.
Legionnaires’ disease usually develops within two to 10 days of exposure. Symptoms include chills, fever, and shortness of breath. It is usually treated with antibiotics.
People are most at risk of contracting Legionnaires’ disease if they have had recent surgery, have a chronic lung disease, or are over 50. They are also more likely to develop the disease if they have a weakened immune system.
While the number of cases reported to the CDC has increased over the past decade, it may not reflect a true increase in the number of people contracting the disease. It is also unclear how many Legionnaires’ disease outbreaks occur in the United States each year.
The cause of Legionnaires’ disease is unknown, but it may be due to exposure to a contaminated water source or a faulty air conditioning unit. CDC investigation protocols include identifying the source of exposure and preventing future outbreaks.
Legionnaires’ disease is treated with antibiotics, usually erythromycin or clarithromycin. Using antibiotics before the disease begins may delay the progression of the disease.
The risk of developing Legionnaires’ disease increases for people who have had recent surgery, a chronic lung disease, or a weakened immune system. Legionnaires’ disease is also common in people who live in an area where there is a large number of man-made water systems.
Legionnaires’ disease can be life-threatening, but treatment is effective. Symptoms include chills, fever, shortness of breath, and diarrhea.
Diagnosis
Currently, Legionnaires’ disease is diagnosed by laboratory analysis of urine, blood, sputum, or other specimens. This type of testing is very important. A Legionella infection may be detected days or weeks after antibiotic treatment.
Legionnaires’ disease is a respiratory infection that usually occurs in persons with weakened immune systems. Symptoms may include fever, cough, and diarrhea. It can also be associated with elevated blood phosphorus and C-reactive protein levels. The condition is often fatal.
Legionella is a bacterium that can be isolated from sputum, pleural fluid, or lung tissue. The bacteria can also be found in warm water systems.
Legionella has been reported in hospitals and long-term care facilities. There are risk factors such as chronic lung disease, organ transplants, and corticosteroid medicines.
Legionnaires’ disease is characterized by high fever, cough, chills, and nausea. It may also result in abnormal liver function tests. People who have had Legionella infection are also more likely to develop gastrointestinal symptoms and multi-system organ failure. It may also lead to elevated creatinine levels.
Legionnaires’ disease can occur anytime but is most common during the summer. In New York State, there are approximately 200 to 800 cases per year. It is also more common in men than women.
Legionella is diagnosed by measuring indirect fluorescent antibody titers in acute sera. A positive result is usually obtained within two to three days of infection. Symptoms may also include headaches, muscle pain, and fatigue.
If Legionella is detected, treatment is recommended. There are several types of antibiotics available. Treatment can be started within three days. It is important to get treatment as soon as possible to reduce the risk of complications. The treatment can reduce health costs and prevent secondary infection.
Treatment
Traditionally, treatment of Legionnaires’ disease involves antibiotics. However, some patients may require hospitalization. In the United States, up to 18,000 people are hospitalized with Legionnaires’ disease annually.
Legionnaires’ disease can be fatal. Early detection may prevent long-term complications. It is important to report Legionnaires’ disease in order to prevent other people from getting it.
Fluoroquinolones are the most active anti-Legionella antibiotics. These antibiotics should be used as first-line therapy for Legionnaires’ disease. However, they may need to be given in extended courses.
The optimal duration of antibiotic therapy for Legionnaires’ disease is not known. This may depend on the severity of the illness and how patients respond to treatment.
In the past, the most commonly used anti-Legionella drug has been erythromycin. However, this drug has a number of adverse effects. Other antibiotics such as tetracycline and tigecycline are also options for Legionnaires’ disease treatment.
The most common diagnosis for Legionnaires’ disease is based on clinical symptoms and laboratory tests. Sputum cultures and chest X-rays are common diagnostic procedures.
The economic burden of Legionnaires’ disease is approximately US$ 835 million. This includes premature deaths, absenteeism, and productivity losses. When lifetime productivity losses are added, the total economic burden is over US$ 1.3 billion.
Early detection of Legionnaires’ disease reduces the risk of serious complications and shortens the recovery period. Antibiotic therapy should be given as early as possible to avoid the development of drug resistance.
Several studies have shown that fluoroquinolones are effective in Legionella pneumonia. However, most published studies are observational and susceptible to confounding.
Other treatments for Legionnaires’ disease include tigecycline, levofloxacin, and azithromycin. However, these antibiotics may not be easily available. They may be used as extended-spectrum fluoroquinolone therapy in hospitalized patients.
Prevention
Various professional organizations have developed legionellosis prevention guidelines. These guidelines differ in technical detail but also share common recommendations.
Legionnaires’ disease, caused by the bacteria Legionella, is an airborne disease that can cause serious illness and even death. It usually occurs in people who have pneumonia. It is usually caught by breathing in fine droplets of water.
Legionella bacteria grow in warm, contaminated water and can multiply inside water systems. They are most often found in freshwater but can also be found in artificial systems that use water.
The symptoms of Legionnaires’ disease include chills, fever, coughing, muscle aches, and shortness of breath. Symptoms can last for days or weeks. If you suspect you may have been exposed to Legionella, seek medical attention immediately.
People with underlying health problems such as asthma, chronic lung disease, and immune system disorders are at increased risk. The elderly, people with HIV/AIDS, and people with a weakened immune system are also at risk.
The best way to prevent Legionnaires’ disease is to maintain clean and healthy water systems. You should clean and disinfect your water system at least once every two weeks. If you own a water system, you should contact the local health department to ensure it is properly maintained.
People who are immunocompromised are more likely to get Legionnaires’ disease. These patients often have underlying health conditions such as asthma, a weakened immune system, or kidney failure.
Legionnaires’ disease can be caught from natural water bodies, but is also found in potting mix and artificial water systems. If you own or rent a water system, you should contact the health department and get the system tested.
Legionnaires’ disease is a serious lung infection. It can be treated with antibiotics. It usually has an incubation period of two to ten days. However, in severe cases, it can lead to respiratory failure and even death.
