Chief Medical Officer Dr Tony Holohan said: “While we now have a robust testing system in place.
"The success of this system is dependent on people isolating and coming forward to their GP as soon as they experience symptoms.
"Cough, fever, shortness of breath, change in smell or taste, flu like symptoms should be treated as COVID-19 until a GP assessment or test deems otherwise.
"If you are experiencing these symptoms, do not go to work or socialise. Self isolate in your household and contact your GP by phone without delay."
There have been 404,989 tests carried out since the outbreak began.
Just 0.5% of the 18,386 people tested in Ireland over the past seven days were diagnosed with the virus.
The HSE said it is working to identify any contacts the patients may have had to provide them with information and advice to prevent further spread.
