Drivers told lethal bug can be beaten by wiper fluid

Drivers who do not use screenwash for their windscreen wipers risk getting potentially deadly legionnaires' disease, a study revealed today.

The warning comes after experts discovered professional drivers were five times more likely to be infected with the bug, which is found in warm, stagnant water.

Drivers are now being urged to add screenwash to their wiper water after traces of the legionella bacterium were found in one in five cars that did not have the additive -- but in no cars that did.

It is feared around 20pc of legionnaires' disease cases could arise from this type of exposure.

The findings come from a UK study, which looked at why people at the wheel were more likely to be infected.

Most at risk were found to be those driving a van, people who drive through industrial areas, and people who often had the car window open.

But the "most intriguing" higher-risk group was drivers not using screenwash -- which kills off the legionella bug, the study authors found.

They said: "Not adding screenwash to windscreen wiper fluid is a previously unidentified risk factor and appears to be strongly associated with community-acquired sporadic cases of legionnaires' disease.

Stagnant, warm water is a breeding ground for the legionella bacterium, which causes a potentially fatal lung infection. It is contracted when small droplets of contaminated water are breathed in, and cannot spread from person to person.

An estimated 10pc of people who contract the disease die.
