Stagnant, warm windscreen washer water could after 20% of cases sporadic disease in England and Wales, according to the health protection agency (HPA).
The European Journal of epidemiology, the research found wiper liquid without Screenwash ideal breeding conditions for Legionella bacteria provides the potentially deadly pneumonia can cause.
If the water on the windscreen is sprayed, tiny droplets can car in through the ventilation system and be inhaled.Adding Screenwash kills bacteria, but says the HPA.
Finding that professional drivers five times more likely are treaty than expected in the disease, researchers at the HPA examines the causes. While they found that those who are in a van, traveled through industrial areas, or who had often been open the window at increased risk, use the largest factor identified as failure Screenwash.
Traces of the Legionella bacteria were found in one of five vehicles not Screenwash added in the windscreen washer water have.However, it was not present in, if any had added, facilitate the liquid that is designed to clean the windscreen.
Although it is not contagious, the disease can groups particularly dangerous, how sein.Es tends elderly or those with already existing health problems to more common in the over 50s, among men, while up to 15% of cases fatal.
However, could according to NHS selection, the actual number of people, the disease every year contract because of misdiagnosis of flu-like symptoms far higher. during outbreaks cooling towers or pools allocated, is rarely identified the source of sporadic cases.
Professor of bacteriology Hugh Pennington told BBC Radio 4's today programme that the research is a statement, what has a secret been stagnant, warm water describes as "happy hunting ground for the bug".
"We know that a whole bunch of people to get without disease in an outbreak without with each risk factors particular... and here the explanation," he added.
"The screen wash kills the bug, stops it grows, it kills, and of course your windscreen cleaning, is it a bit like a no-brainer really put it in there."
