Surveillance testing is being carried out across the Islands bus drivers.
It comes after a number of drivers tested positive for Covid-19 this month and nearly half are understood to be self-isolating.
Bus Vannin says the surveillance initiative is available to any driver who wants it.
When asked about the matter in the House of Keys this morning, Chief Minister, Howard Quayle MHK, said the DOI expects to receive the results of the testing in a few days.
