Today's figures bring the total number of cases in Ireland to 37,668.
As of this morning, there were 118 confirmed cases in hospitals and 20 in intensive care.
Of today's cases, 315 are men and 294 are women. 68% are under 45 years of age, and 30% are associated with outbreaks or are close contacts of a confirmed case.
58 cases have been identified as community transmission.
Of today's cases, 224 are in Dublin, 58 in Donegal, 46 in Cork, 44 in Kildare, 31 in Limerick, 28 in Laois, 21 in Kerry, 19 in Galway, 17 in Clare, 13 in Meath, 12 in Louth, 12 in Monaghan, 9 in Offaly, 9 in Tipperary, 9 in Wicklow, 8 in Cavan, 8 in Wexford, 7 in Carlow, 7 in Sligo, 7 in Roscommon, 6 in Mayo, 5 in Kilkenny, 5 in Westmeath, with the remaining 7 cases in three counties.
Acting Chief Medical Officer Dr Ronan Glynn said: "The numbers being reported today and over the past week represent a significant escalation in the profile of Covid-19 in Ireland.
"For those aged 70+ and those who are medically vulnerable to Covid-19, it is strongly recommended that you should limit the number of people you meet to a very small core group of family members, carers or friends, for short periods of time, while remaining physically distant.
"We need to work together once again to make a significant impact on the number of cases in the community, and ultimately to reduce the number of people getting sick, being admitted to hospital and critical care, while protecting non-Covid healthcare services. I urge people in every county to follow the public health advice to stop the further spread of Covid-19," he added.
The #COVID19 cases remain very high. Thankfully those in hospital have come down slightly. Now at 113 people, with ICU numbers steady at 21. Let's hope they all make a good recovery. We will get through this. Have a nice weekend and #StaySafe @HSELive— Paul Reid (@paulreiddublin) October 3, 2020
Meanwhile, more than 900 family outbreaks of Covid-19 were reported in September.
In recent days, public health advice to limit social interactions to between just two households at any one time was extended nationwide, as health officials here say the national situation is a serious concern.
The figure is published by the Health Protection Surveillance Centre and takes account of cases reported up until midnight on 30 September.
924 family outbreaks of the virus occurred last month, compared to 530 family outbreaks in August.
This is a significant increase from 127 family outbreaks in July, 126 in June, and just 94 in May, when restrictions were in place.
Meanwhile, Ireland's 14-day incidence rate of Covid-19 has increased to 100.9. This is the number of cases of the virus per 100,000 of the population.
The figure is measured from the number of new cases of the virus reported between 18 September and midnight on Thursday, 1 October.
This compares with a national rate of 32.7 a month ago, the rate recorded in the 14 days up to 3 September.
The latest data shows that Donegal continues to have the highest 14-day incidence rate, at 233.1, followed by fellow border county Monaghan, at 172.2.
Dublin has a rate of 168.2, while Roscommon and Longford are both above the national rate at 134.8 and 119.9 respectively.
Health Service Executive CEO Paul Reid has said there are 113 people with the virus in our hospitals, with 21 patients receiving treatment in ICU.
Figures last night from the HSE showed there are 234 critical care beds currently occupied, and there are 39 adult critical care beds available nationwide.
