Legionnaire's risk for professional drivers
Survey participants were asked questions on their driving habits, potential sources in vehicles and known risk factors. There were two types of exposure linked to vehicles – driving through industrial areas, and driving or being a passenger in a vehicle with windscreen wiper fluid not containing added screenwash. The researchers said that not adding screenwash is a previously unidentified risk factor and appears to be strongly associated with sporadic cases of Legionnaires' disease. They estimate that around 20% of community-acquired sporadic cases could be attributed to this exposure that using screenwash may help stop the transmission of bacteria to drivers and passengers.

Research by the Health Protection agency has found that people who drive for a living are five times more likely than anyone else to get Legionnaire's disease – and windscreen wiper water could be to blame.
