London, Dec 5 (ANI): A train passenger's single sneeze can infect 150 commuters with a cold, warn medical experts after studying 1300 commuters.
The 'blast' shoots 100,000 droplets into the air at 90mph - when unchecked by a handkerchief, the experts found.
And in another five minutes germs can invade the systems of 150 people who pick them up from seats, doors, station escalator handrails and other surfaces.
Going by the results, the Department of Health in the UK is urging besieged Brits to combat the cold - by carrying tissues everytime.
"We're trying to raise awareness so people alter their hygiene habits," the Sun quoted a rep, as saying. (ANI)
