LIBRARY and theatre-goers who feel unwell are advised to visit their doctor in case they have Legionnaires' Disease.

Bromley Council has issued the advice after a case of the disease was confirmed in a maintenance engineer working at the Central Library/ Churchill Theatre complex.

The risk to the public is low but anyone who has worked or spent time in the library or theatre during the past three weeks and is displaying flu-like symptoms including muscle aches, tiredness, headaches, dry cough and fever, should visit their doctor.

Although the incubation period normally ranges from two to 10 days, people can develop symptoms as late as three weeks after exposure.

A thorough investigation is under way by the council's environmental health team and the Health Protection Agency to discover whether the cooling tower at the library in Bromley High Street is the source.

Samples are currently being analysed and the results will be available early next week.

The cooling tower has been shut .

A Bromley Council spokesman said: "The council's priority remains the welfare of those visiting and working in the complex."

A Churchill Theatre spokesman said: "The London Borough of Bromley has reassured the theatre there is no risk to the health of any audience members attending shows."

Legionnaires' Disease is a form of pneumonia, often found in air conditioning cooling towers and hot and cold water systems in factories, hotels and hospitals. The majority of cases are isolated but outbreaks can occur.

All ages can be affected but it mainly affects people over 50 years of age, and generally men more than women. It is not contagious.

Details about the engineer's identity and condition have not been released.
