Community assessment hubs will start accepting referrals and seeing patients with suspected cases of coronavirus from the middle of the week.
The service to test for Covid-19 is starting today but only to train staff.
There have now been almost 5,000 confirmed cases in Ireland with 158 people losing their lives to the virus.
There are now 17 confirmed cases in county Longford, 15 in Roscommon and 13 in Leitrim.
The hubs will be located in the country’s primary care centres and will be open 7 days a week, but patients will have to be referred by their GP.
HSE chief operations officer, Anne O’Connor, says the hubs will ease pressure on GPs and hospitals.
