[아시아경제 박혜정 기자] Legionella is a common infectious disease caused by Legionella inhabiting the water each summer. Legionella can exist anywhere with water. It is mainly in contaminated water such as water tower cooling, air conditioner, shower, faucet, humidifier, fountain, bathtub, steam room and so on.
Legionella infection is divided into type of influenza and type of pneumonia. Influenza is common in people with no underlying disease. Mild symptoms such as fever, chills, headache, muscle aches, dry cough, runny nose, etc. usually develop without improvement after 2 to 5 days. Pneumonia occurs mainly in patients with chronic lung diseases, smokers and immune deficiency. In addition to fever after 24 hours, the lungs become inflamed, causing a cough, difficulty breathing. It can often accompany serious complications such as myocarditis, epicarditis, sinusitis, bronchitis, peritonitis, pyelonephritis.
Legionella can be pbaded on to anyone. Special attention should be given to increased risk of infection, such as chronic pneumonia, smokers, diabetic patients, kidney patients and immunocompromised patients. For pneumonia, about 14 days of antibiotic treatment is needed.
Kim Yang-hyun, professor of family medicine at Anam University of Korea University, said: " In the early stages of legionellosis, there is no no distinguishing symptoms that distinguish it from other illnesses like colds.If you use a cooler on cough, it should prevent fatigue, headaches and fever symptoms, such as symptoms of fever. a specialist, "advises Professor Kim Yang-hyeon:" In particular, if people in the same room have similar symptoms such as dry cough, fatigue and fever, it is necessary to check if it's Legionella. "
To prevent legionella, regular disinfection and inspection of air conditioner filters and coolers are essential.Cooling towers and hot and cold water installations in most large buildings are well managed, but in some, Legionella is often found.
At home, it is best to clean the air conditioner filter every two weeks and ventilate it frequently, for example by opening the window at least every 3 to 4 hours a day. Fresh air must be supplied to the room and adequate humidity must be maintained. The management of vehicle air conditioners is easy to overlook, but the space is restricted and closed, so management should be completely done. Preventing the growth of bacteria or fungi through periodic filter replacement and interior cleaning will help maintain healthy indoor air and prevent the presence of legionella.
