炎热的夏季,空调器在给人送来阵阵凉意的同时,一种寄生在中央空调的冷却水塔和管道中的致病菌,通过通风口大举进入写字楼、商厦内部,威胁着人们的健康。 这种致病菌称军团菌,它是一种水源微生物,当水温在31—36℃时可长期存活。我国某市曾对四星级、五星级大饭店空调冷却水塔进行监测,发现军团菌污染率高达85.7％。军团菌病暴发流行多在夏秋季,主要通过空气传播,经呼吸道吸入体内,容易发生在配备有中央空调的封闭式环境里。军团菌病主要分为两种类型,一类为肺炎型,其初发症状为全身不适、疲乏、肌肉酸痛、头痛、发热、咳嗽、胸痛、咯血、呼吸困难等,病菌还能侵犯消化系统、中枢神经系统,重症病人可出现肝功能变化及肾功能衰竭,并可出现精神紊乱等;
In the hot summer season, air conditioners send bursts of cool air, meanwhile, a kind of pathogens parasitized in cooling towers and pipes of central air-conditioners enter the office buildings and commercial buildings through vents and threaten people’s health. This pathogen, called Legionella, is a watery microorganism that can survive long-term at 31-36 ° C. A city of our country had four-star, five-star hotel air-conditioned cooling towers were monitored and found that Legionella contamination rate as high as 85.7%. Legionella outbreaks epidemic mostly in summer and autumn, mainly through the air, inhaled through the respiratory tract, prone to occur in a closed environment equipped with central air conditioning. Legionnaires disease is divided into two types, one type of pneumonia, the initial symptoms of general malaise, fatigue, muscle soreness, headache, fever, cough, chest pain, hemoptysis, dyspnea, bacteria can also invade the digestive system, Central nervous system, severe cases of liver function may occur changes and renal failure, and mental disorders may occur;
