Legionnaires’ disease, a rare disease, is a severe bacterial infection affecting respiratory tract (pneumonia). The organism involved in this condition is Legionella pneumophila that usually founds in mist from hot tubs, air-conditioning units and showers. Transmission occurs by breathing in mist from water that contains these bacteria. General symptoms include fever, cough, chills, muscle pain and headaches.

Windscreen wiper may cause Legionnaires disease A recent study found that “Windscreen wiper water may be the cause of 20% of cases of Legionnaires’ disease and adding screen-wash to wiper fluids could save lives”. This finding is based on a case-control study which surveyed the driving habits and known risk factors of the Legionnaires’ disease. They study was conducted after an unusual high number of cases were reported in England and Wales and around this time it was well established that professional drivers were five times more likely to get Legionnaires’ than people from other lines of work. The study was aimed to further explore the possible reasons for the difference between the occupations.

The researchers contacted the 75 surviving cases who had acquired Legionnaires’ disease and also included 67 control people without the disease. The participants were provided with a questionnaire asking about their driving habits, other recognized risk factors and possible illness sources in the vehicles. They were asked what kind of vehicle they drove, its age, car service history, content of the wiper fluid tank and whether their driving was for societal or occupation reasons.

The results showed that two factors were associated with a high likelihood of being infected: driving all the way through industrial areas and driving or being a traveler in a motor vehicle that used windscreen wiper fluid with no screen-wash. The researchers calculated that about 22% of infections in people could be due to driving or being a traveler in a car that did not use screen-wash in the windscreen wiper fluid. The detected a firm link between people who do not use screen-wash and the danger of Legionnaires’ disease. Although because of case-control nature of study it cannot confirm causation, the investigators state there is a reasonable biological connection. They believe it is plausible that the bacteria grow in the sluggish water of the wiper’s fluid tank that can become an aerosol when it is sprayed onto the windshield.

Though not proved causal relation, until more conclusive results comes, it is advisable to add screen-wash to your car’s wiper fluid as it can limit the transmission of bacterial causing Legionnaires’ disease.
