A team of experts from the University of Nottingham in the UK and the National Institute of Health and Welfare in Finland published a paper in BMC Journal of Infectious Diseases. Research shows that the airport security disk is the biggest culprit in the spread of airport pathogens. So the next time you put your mobile phone, passport and laptop in the safety tray-maybe hand sanitizer is worth it.

In the winter of 20 16, the research team monitored the bacterial levels on the surfaces of various objects at Wanda airport in Helsinki, Finland. They found 10% virus signs on the surface of all tests, which will definitely make purists crazy on the road. Other hot spots of bacteria are payment terminals in shops, stair handrails, passport counters, children's playgrounds and inevitable air. Rhinovirus causes the common cold and some flu symptoms.

Jonathan Fantram, a professor of health protection at the University of Nottingham School of Medicine, said in a statement: "This study confirms the case of how virus infection spreads to raise public awareness." People can wash their hands at any time and cover their mouths with handkerchiefs, paper towels or sleeves when coughing to reduce infection, especially in public places. His team partner, Nina Ikonen, a virologist at the Finnish National Institute of Health and Welfare, added: "The research results also provide a new concept of technical improvement for airport design and renovation." At the end of the research paper, the research team suggested that airports can "provide opportunities for hand disinfection in areas with serious and frequent contact with the ground before and after security inspection".

At the same time, it is necessary to strengthen disinfection of surfaces that are in frequent contact, such as safety inspection boards. It is pointed out that touching the plastic safety tray is almost inevitable.
