Anyone who has used the showers at Beau Sejour in the last two weeks and start feeling ill should seek medical advice and tell them they may have been exposed to Legionella.
The leisure centre has been shut with immediate effect after routine testing found Legionella bacteria in its water system.
Legionella can cause Legionnaires’ Disease, a form of pneumonia which can develop when contaminated water droplets are inhaled.
Legionnaires’ Disease can be serious, with around one in 10 cases resulting in death. Older people and those with weakened immune systems are at greater risk.
However, most people exposed to Legionella do not become unwell.
What do if you’ve showered at Beau Sejour?
Symptoms usually develop between two and 14 days after exposure.
The leisure centre will remain closed throughout Tuesday and Wednesday while further investigations and testing are carried out.
The preliminary test result was received on Monday afternoon, when the centre’s showers were immediately closed.
Further investigations have now led to the decision to close the whole centre while officials work to identify the cause and carry out further testing.
Public Health says it does not currently know of any cases of Legionnaires’ Disease in the community.
The bacteria cannot be passed from person to person, and the risk of illness to individuals remains low.
Anyone who develops symptoms after using the showers should seek medical advice.
Symptoms can include a high temperature or fever, a cough, shortness of breath, chest pain, muscle aches and headaches.
Symptoms usually develop between two and 14 days after exposure.
The centre will not reopen until it has been confirmed safe.
It is hoped Beau Sejour can reopen in time for the weekend, with teams also working to minimise the impact on upcoming events.
An update is expected on Wednesday afternoon.
Further information will be published through States of Guernsey and Beau Sejour social media channels.
