A new study from the University of Nottingham shows that if you've used pubic transport recently, there is a 6X increase in developing an acute respiratory infection.
Study subjects who had recently developed acute respiratory infection symptoms were asked to fill out questionnaires detailing bus or tram use in the 5 days preceding the onset of their symptoms.
Those who used public transport within 5 days prior to becoming symptomatic were 6 times more likely to develop acute respiratory infections.
What to do?
Not a lot. Wash your hands after getting off the bus, try not to touch too many surfaces, and don't lick the hand rails.
