The Western Swimming Pool says a visitor who was at the venue earlier this week has tested positive for Covid-19.
The team there says the individual attended an organised session there on Monday evening (March 1) between 5.30pm and 6.30pm.
Anyone else who was in the group session who might have been affected will be contacted by the contact tracing team.
Meanwhile, anyone who goes on to develop symptoms of the virus is asked to self-isolate straight away and contact 111.
The pool adds it has maintained the highest possible hygiene standards and hopes to welcome customers back when the circuit-break lockdown ends.
