New Legionnaires' case brings total in Renfrew outbreak to 11 Health chiefs have confirmed another case of Legionnaires' disease in Renfrew, bringing the total to 11. The latest instance of the bacteria was announced following a meeting of NHS Greater Glasgow and Clyde's outbreak control team. The patient in question is said to be stable and is receiving treatment in hospital. The previous ten cases have now fully recovered. NHS Greater Glasgow and Clyde public health protection unit is working to identify the source of the outbreak. It is being assisted by the Health and Safety Executive, Health Protection Scotland and Renfrewshire Council. All confirmed cases have had a direct or indirect link to Renfrew. All active water cooling towers in the area have been treated with chemicals to kill the legionella bacteria as a precautionary measure and a number of towers have been tested for bacteria. Dr Syed Ahmed, NHSGGC consultant in public health medicine, said: "We have notified all community GPs and our frontline hospital teams to keep this outbreak uppermost in their minds when dealing with patients displaying symptoms of headache, fever, dry cough, breathing difficulties, stomach pains and diarrhoea. Anyone currently displaying these symptoms should contact NHS 24 on 08454 24 24 24 or their own GP. Doctors stressed that legionella cannot be spread through human contact, nor can it be contracted by drinking contaminated water. Instead, it is spread through aerosols produced from water, such as water cooling towers, air conditioning systems and showers.
