CSO statistical release, , 11am

COVID-19 Insight Bulletins: Deaths and Cases, Series 21

Information on the people who have died due to COVID-19 or have been diagnosed with the virus.

Open in Excel:

The majority of data used in this report is taken from the Computerised Infectious Disease Reporting (CIDR) provided to the Central Statistics Office (CSO) by the Health Protection Surveillance Centre. Due to the large volume of COVID-19 cases in the past number of weeks, the availability of surveillance data on cases is limited. Therefore, some data in this report is incomplete, particularly in relation to details on underlying conditions and health care workers. Similarly, there is a delay in the linking of cases to outbreaks on the national surveillance system (CIDR). Therefore, the number of linked cases to outbreaks in this report is likely to be an underestimate. However, Public Health are prioritising the reporting of outbreaks in key settings e.g. residential care facilities, hospitals etc.

Key Findings:

  • Some 318 people died due to COVID-19 in the week ending 22 January, more than 10% of all deaths to date
  • More than 100 people have died due to COVID-19 in each of the last three weeks
  • The number of cases for the week ending 22 January was 9,311, a decrease of 8,825 cases from the previous week
  • The median age of new confirmed COVID-19 cases was 41 years old for the week ending 22 January
  • In the week ending 22 January, Dublin accounted for 2,906 cases or 31% of all new cases
  • Hospitalisations have been increasing since the week ending 11 December and were 1,298 in the week ending 15 January, the highest recorded
  • The average number of contacts per positive case per week was two in the week ending 22 January, down from three contacts in early January
  • In the last four weeks, there have been 3,294 cases linked to an outbreak in nursing homes, 866 linked to residential institutions and 1,083 linked to hospital or a community hospital/long-stay unit

This is the twenty-first 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 2020 to 22 January 2021.

Confirmed Cases

For the week ending 22 January, the number of weekly cases was 9,311, a decrease of 8,825 from the previous week. The total number of confirmed cases to date is 188,091.

The 25-44 age group still showed the highest number of confirmed COVID-19 cases at 64,049.

This is the second week in a row where the median age of new cases has been over 40. The median age of new confirmed COVID-19 cases was 41 years old for the week ending 22 January.

Dublin accounted for almost a third (2,906) of all new cases for the week ending 22 January and it was the third week in a row that weekly cases in Dublin have fallen. Cork was the county with the second highest number of new cases (1,036) for the week ending 22 January. No other counties had more than 1,000 weekly cases in the week ending 22 January.

This is the third week in a row that Leitrim has recorded less than 100 new cases.

This is the second week in a row that Longford has recorded less than 100 new cases and the first such week for Sligo and Roscommon.

Since the start of the pandemic, some 10,068 more females were diagnosed with COVID-19 than males. 

There were 1,548 health care workers diagnosed in the week ending 22 January, the fourth week with more than 1,000 cases.

Hospitalisations and Outbreaks

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. Hospitalisations have been increasing since the week ending 11 December and were 1,298 in the week ending 15 January, the highest recorded. It is important to note that there is a time lag between onset of symptoms and hospital admissions and trends in confirmed cases in hospitals suggest that the numbers reported for recent weeks will be revised upwards and thus are marked as provisional.

From Table 7, it can be seen that in the last four weeks, 7,527 cases have been linked to an outbreak and of these 3,294 (44%) were in nursing homes, 866 (12%) were in residential institutions and 1,083 (15%) were in hospital or a community hospital/long-stay unit. The over 80 age group made up 22% of all cases linked to an outbreak over this period, this is 40% of all confirmed cases in this age group. Figure 1 displays this recent increase in cases linked to outbreaks in health and residential care settings. An increase in cases linked to outbreaks in hospitals can also be seen in November.

From Figure 2 and Table A, it can be seen that the hospitalisation rate has been relatively consistent since July and was 33 per 1,000 confirmed cases in December, however over the periods when outbreaks in hospitals and nursing homes occurred the hospitalisation rate increased to 72 in November and is currently 56 per 1,000 confirmed cases in January.

The overall ICU admission rate was six per 1,000 confirmed cases. (Note: It is important to note that there is a time lag between onset of symptoms and hospital admission. Also note that January rates are provisional and expected to increase).

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 due to COVID-19 has been greater than 100 for each of the last three weeks.

Since the start of the pandemic, the total number of people who have died due to COVID-19 in Ireland is 2,870, with a further 164 deaths cited as probable deaths linked to the virus. For the week ending 22 January, 318 deaths were recorded.

The virus claimed the lives of 182 more men than women up to and including the week ending 22 January. 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.

There were 93 deaths in Dublin in the week ending 22 January, Cork (53) and Limerick (22) were the only other counties to record more than 20 deaths in the week.

From Table A we can see the overall mortality rate is 18 per 1,000 confirmed cases, this was highest in April at 77 per 1,000 confirmed cases. The mortality rate was six per 1,000 in December and is nine per 1,000 cases in January. (Note: These figures may need to be revised as there is a time lag between onset of symptoms and death.)

Referrals and Testing

There were 123,784 referrals for community testing where a valid reservation was recorded in the week ending 22 January. Referrals for testing decreased in the last week, in particular among the 25 – 44 age groups, which decreased from 53,930 to 48,964 in the week ending 22 January. Some 43% of referrals were from GPs in the week ending 22 January. Analysis on referral speciality type shows that while residential settings' / institutions / schools’ referrals for testing have remained consistent for the last number of weeks - general COVID-19 testing has dropped by 9,041 while healthcare / essential worker testing has increased in the week ending 22 January.

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 there were 155,939 tests completed in the week ending 22 January. The positivity rate in the week ending 22 January was 10.8%, down from 15.4% the previous week.

Underlying Conditions

Due to the recent surge in cases there is a large volume of deaths and cases where underlying cases are unknown. Therefore, the recent numbers of cases with underlying conditions are likely to be underestimated.

Since the start of the pandemic, there have been 2,258 deaths of people with underlying conditions from 27,280 confirmed cases with underlying conditions. The median age of those dying with underlying conditions is 83.

There were 2,092 deaths of people with underlying conditions in the over 65 age group. Of the 198 deaths in the 25-64 age group, 165 had underlying conditions.

In terms of underlying conditions, chronic heart disease was present in 43% of deaths.

Contacts

The average number of contacts per positive case per week was two in the week ending 22 January, down from three contacts per case in early January. This implies details of more than 18,000 close contacts were recorded in the week.
