Key Findings:
This is the fifteenth publication in our series of information bulletins produced by the Central Statistics Office (CSO), that aim to provide insights into those who have either died from or contracted COVID-19, by using data from the Computerised Infectious Disease Reporting (CIDR) provided to the CSO by the Health Protection Surveillance Centre and data from the HSE’s Swiftcare (A2i) and COVID Care Tracker (CCT) systems. This Bulletin covers the period from 28 February to 30 October 2020.
Referrals and Testing
There were 75,837 referrals for community testing where a valid reservation was recorded in the week ending 30 October. Referrals for testing have decreased in the last week, in particular among the 0 – 14 age group, which has fallen from 18,629 to 10,935 in the week ending 30 October. Some 57% of referrals were from GPs in the week ending 30 October.
Testing numbers cannot be directly compared with referrals for community testing; there is a significant number of tests completed in hospitals as well as a time lag between referral and test completion. Several referrals also do not result in a test being completed. However, weekly testing numbers from HSE labs and hospitals show that there were 99,657 tests completed in the week ending 30 October. The positivity rate in the week ending 30 October was 5.3% down from 6.6% the previous week.
Confirmed Cases
The number of weekly confirmed COVID-19 cases is less than 5,000 cases for the first time in the last four weeks up to and including 30 October. The total number of confirmed cases is 62,415. The number of cases for the week ending 30 October is 3,881, a decrease of 2,546 from the previous week.
Dublin accounted for almost a third (1,202) of all new cases for the week ending 30 October and it was the seventh week in a row that Dublin had more than 1,000 weekly cases since the beginning of March. Cork is the county with the second highest number of new cases at 570 cases, for the week ending 30 October.
Cases in Dublin have not been decreasing at the same rate as the rest of the Ireland (see Figure 1), however cases in Dublin also had a different pattern of increase to the peak, week ending 16/10, to the rest of Ireland.

Just under half (48%) of all confirmed cases are linked to an outbreak.
Some 3,862 more females were diagnosed with COVID-19 than males.
The 25-44 age group still show the highest number of confirmed COVID-19 cases at 20,380.
The median age of new confirmed COVID-19 cases was 33 years old for the week ending 30 October and has been below 40 for new cases since the end of June.
In the week ending 30 October, 175 of confirmed cases or 5% of all cases were among health care workers.
Hospitalisations
Table 6 shows weekly hospitalisations and admission to Intensive Care Units (ICU), these are dated using the epidemiological date of infection and so can be compared with confirmed cases. The peak week for admissions to hospitals was the week ending 27 March when 688 of the 3,428 cases were admitted to hospital, a further 95 of these were admitted to ICU. In comparison, of the 3,881 confirmed cases in the week ending 30 October, 126 have been admitted to hospital and less than five people to ICU.
The overall hospitalisation rate is 87 people per 1,000 confirmed cases, this was highest in March at 192 per 1,000 confirmed cases and was 32 in October. The overall ICU admission rate is nine per 1,000 confirmed cases, this was also highest in March at 27 per 1,000 confirmed cases and was five per 1,000 in September and three per 1,000 in October. (Note: There is a time lag between onset of symptoms and hospital admission. Also please note that October rates are provisional).
Mortality Rate | Hospitalisation Rate | ICU Rate | ||
March | 48 | 192 | 27 | |
April | 74 | 141 | 11 | |
May | 41 | 140 | 10 | |
June | 38 | 121 | 0 | |
July | 0 | 63 | 0 | |
August | 5 | 40 | 4 | |
September | 5 | 45 | 5 | |
October | 3 | 32 | 3 |
Deaths
The results produced by the CSO in Table 2 are based on the Actual Date of Death. Using this method, the CSO has found that the number of people who have died from COVID-19 has been greater than 10 for each of the last eight weeks, Dublin continues to be the worst hit.
The total number of people who have died from COVID-19 is 1,679, with a further 229 deaths cited as probable deaths linked to the virus. For the week ending 30 October, 30 deaths were recorded.
The virus claimed the lives of 61 more men than women up to and including the week ending 30 October. It also continues to impact the older age groups the hardest, with 64% of all confirmed COVID-19 deaths to date in the 80 years old or older age group.
From Table A we can see the overall mortality rate is 26 per 1,000 confirmed cases, this was highest in April at 74 per 1,000 confirmed cases but has been five and three per 1,000 in September and October respectively. (Note: These figures may need to be revised as there is a time lag between onset of symptoms and death.)
Outbreaks
There have been 29,664 positive COVID-19 cases linked to an outbreak, which is defined as two or more cases in the same location and time. Women account for 51% of all cases linked to an outbreak.
The median age of confirmed cases related to an outbreak is 32.
For the week ending 30 October, 42% of cases linked to an outbreak are under 25 years old.
Donegal, Galway and Mayo made up 45% of all cases linked to an outbreak for the week ending 30 October.
Outbreaks in private houses account for 49% of cases linked to an outbreak in the last four weeks, nursing homes account for 9% while childcare facilities and schools together account for 9% of cases linked to an outbreak in this period.
Underlying Conditions
There have been 1,568 deaths of people with underlying conditions from 15,570 confirmed cases with underlying conditions. The median age of those dying with underlying conditions is 83.
There were 1,450 deaths of people with underlying conditions in the over 65 age group. Of the 133 deaths in the 25-64 age group, 116 had underlying conditions.
In terms of underlying conditions, chronic heart disease was present in 44% of deaths.
Contacts
The average number of contacts per positive case per week is three in the week ending 30 October, down from six contacts per case six weeks ago. This implies details of more than 11,000 close contacts were recorded in the week. The number of contacts in the 15-24 age group has decreased to three contacts per case in the last week of October from just over six in early October.
