Hong Kong media outlet Hong Kong 01 reported on the 27th that a series of passengers bringing in and using disposable seat covers on China's high-speed rail is sparking controversy. In China, many travelers used high-speed rail during the Mid-Autumn Festival holiday, but due to hygiene concerns, a series of passengers brought in disposable seat covers made of non-woven fabric, etc., and used them to cover their seats. Concerns are spreading in China, including information circulating that people have contracted skin infections via high-speed rail seats. Online, opinions are divided, with voices saying, "There's no problem since they pay for it themselves," and "Seat covers are useful because ill-mannered passengers sometimes step on the seats with their shoes on." On the other hand, other opinions included, "People with normal immunity don't need to do this," and "Disposable covers are not necessarily cleaner." A customer service representative for China's railway platform "12306" responded, "Typically, seat cushions are replaced and cleaned every 120 to 180 days. Sheets for sleeper berths are replaced after each passenger, and if dirt is found, they are cleaned immediately." Dr. Ma Yiming (Ma Yi-ming) of the Dermatology Department at Beijing Hospital of Traditional Chinese Medicine affiliated with Capital Medical University stated, "While these seat covers can prevent direct contact with potential pathogens remaining on the seats and reduce the risk of indirect infection," he also said, "These products do not have special functions such as anti-inflammatory, antibacterial, or antiviral properties," indicating that their effectiveness is limited.
