675 visit have been made to those self-isolating since July 20.
It's one of the figures revealed by Chief Minister, Howard Quayle MHK, in written response to a Tynwald question from Onchan MHK, Julie Edge earlier this week.
Ms Edge had asked Mr Quayle how many people had left and returned to the Island from that date as well as how many had checks carried out by mobile calls, landline calls and physical visits to their place of quarantine.
July 20 saw the Isle of Man move to stage four of its border policy around Covid-19 - which meant residents would be able to leave the Isle of Man as they wish but would need a Manx Entry Permit to return and would then have to self-isolate for two weeks on arrival.
Non-residents are still prohibited from coming to Manx shores unless they have an exemption certificate.
The only exception to the current border policy is Guernsey, with whom the Island shares a 'travel corridor' which opened in July.
Meanwhile, the Chief Minister also revealed whilst the government does not hold details on how many residents have left the Island, 4,457 'landing cards' to come back had been completed since July 20.
Elsewhere, 3,409 people who've gone into isolation after arriving here by air or sea were checked on with a phone call as of Tuesday this week.
