A new study estimates that passengers at the world’s top 10 airports can significantly reduce the spread of many infectious diseases by increasing hand washing rates. The better the hand washing habits of airport passengers, the more effective the spread of disease is. The study was published in December, before the outbreak of China’s new crown. The study authors believe the results apply to emerging new coronary outbreaks.
The study estimates that only one in five airport passengers have clean hands – that is, washed with soap and water an hour ago for at least 15 seconds. Four out of five people are potentially contaminated with a variety of bacteria. According to the authors, only 70 percent of people who go to the toilet wash their hands, while only half of those who wash their hands wash their hands correctly, washing them with soap and water for 15 to 20 seconds. The study estimates that if three-fifths of people wash their hands correctly, it could help reduce the rate of spread of infectious diseases by 70 percent. The policy, implemented at 10 airports in the outbreak area, can slow the spread of infectious diseases by 37%.
