Everyone knows that coughing and sneezing can spread germs and viruses. A new study in the UK shows that in densely populated areas during peak hours, a sneeze can transmit the cold virus to 150 people within 5 minutes.
Cold and flu expert Dr. Roger Enderson analyzed the results and found that when a person sneezes, they can spit 100,000 saliva droplets at a time. These droplets spread in the air at a speed of at least 145 kilometers per hour. .
Unless the sneezing person covers his mouth with a tissue or handkerchief, the bacteria and viruses contained in the saliva can be attached to the armrests, seats and other places that will be constantly scratched and touched within 2 seconds.
According to Dr. Enderson’s calculations, 10% of people will come into contact with places “infected” by these sneezes. In crowded places such as station escalators, 150 people will be “infected” within 5 minutes.
