The Island's contact tracing team is 'hopeful' they may be able to identify a link to an unknown case confirmed yesterday.
It comes as one new Covid-19 case was classed as 'unexplained' following four consecutive days of no unexplained cases on Manx shores.
Chief Minister, Howard Quayle MHK said he knows the news will be disappointing.
However he added contact tracing is continuing and the team are hopeful they may yet be able to identify a link to an existing case.
As of yesterdat - the Island's number of active cases stands at 340.
After four days of no new unexplained cases I know it will be disappointing for everyone to see a new case that we cannot currently trace back to someone else with the virus. Contact tracing is continuing and the team are hopeful they may yet be able to identify a link. https://t.co/7iJZOPJirz— Howard Quayle (@HowardQuayleMHK) March 30, 2021
