One of Ramsey Town Commissioners refuse teams is self-isolating after a team member tested positive for Covid-19.
The authority says the other two crew members in the working 'bubble' have been contact-traced, advised to self-isolate, and will also be tested.
Due to safety arrangements in place, no other personnel have been asked to quarantine.
Officials add after being informed the affected team was immediately stood down and staff facilities and refuse vehicles have been deep cleaned as an additional precaution.
Chair of the Commissioners, Andy Cowie, says: "We are obviously very concerned to hear that one of our employees has contracted the virus and we send our best wishes for a quick recovery.
"At the outset of this and the earlier lockdowns the Commission has implemented a number of service changes to protect its workforce and the public from this virus.
"It is not yet known how the infection was acquired, however, we would reiterate our request that households who are self-isolating should double bag any personal refuse and put it aside for 3 days before placing in the refuse bin.
"We would also request householders, where possible, to continue to disinfect their wheely bin handles when they place them out for collection and when bringing them back into the curtilage of their property, and encourage everyone to maintain good hygiene practices throughout."
