夏季首开空调，警惕肺部感染（服务窗）

Core Viewpoint - The article discusses the health risks associated with using air conditioning systems that have not been properly maintained, particularly the risk of Legionnaires' disease caused by Legionella bacteria proliferating in stagnant water within air conditioning units and other water systems [1][2]. Group 1: Health Risks - Legionnaires' disease is a severe lung infection caused by Legionella bacteria, which can lead to symptoms such as high fever, severe cough, and difficulty breathing [1]. - The bacteria thrive in warm, moist environments, making uncleaned air conditioning cooling towers, showerheads, and hot water pipes potential breeding grounds [1]. - The disease is more prevalent from June to September, particularly affecting individuals with chronic respiratory diseases or weakened immune systems [1]. Group 2: Prevention Measures - Regular cleaning and disinfection of water systems, including air conditioners and water heaters, are essential to prevent bacterial growth [2]. - It is recommended to wear a good quality mask during cleaning to avoid inhaling pathogens [2]. - For water fixtures that have not been used for a long time, it is advised to let the water run for one to two minutes before use to flush out stagnant water [2]. Group 3: Summer Cooling Tips - Before using air conditioning for the first time in summer, it is important to thoroughly clean the filters and condensate trays [2]. - Setting the air conditioning temperature around 26 degrees Celsius and ensuring proper ventilation every two to three hours is recommended [2]. - When swimming, it is advisable to choose well-disinfected pools and avoid inhaling mist from cooling devices [2].
