A virus that has not previously been seen in humans was identified in Wuhan, China in December 2019. The World Health Organization (WHO) declared the outbreak a Public Health Emergency of International Concern on 30 January 2020.

In February 2020, the WHO officially named this new Coronavirus ‘COVID-19’. This type of Coronavirus is also known as SARS-CoV-2. The WHO data on COVID-19 globally, showed there were approximately 7 million cumulative deaths due to COVID-19 up to March 2024. 

Report on COVID-19 Deaths Reported in Ireland

The quarterly Report on COVID-19 deaths reported in Ireland (PDF 241 KB) is published by the Health Protection Surveillance Centre (HPSC). This report includes data for COVID-19 cases notified on Computerised Infectious Disease Reporting (CIDR) system up to and including midnight on 30/03/2024 who have been notified as COVID-19 deaths. The latest report on COVID-19 deaths reported in Ireland was on 30/03/2024.

Cumulative data on COVID-19 deaths in Ireland reported that there were 9,559 deaths from the 01/03/2020 to the 30/03/2024, of which 4,460 (46.7%) were female and 5,099 (53.3%) were male.

Over this time period the median age was 82 years and the mean age was 80 years.

Around 74% of COVID-19 deaths occurred in persons aged over 75 years old. See Table 5.1.

This indicator is measured indirectly through the proportion of children 5 years of age who have developed chronic HBV infection (i.e. the proportion that tests positive for a marker of infection called hepatitis B surface antigen [HBsAg]).

Hepatitis B surface antigen: a protein from the virus’s coat. A positive test for HBsAg indicates active HBV infection. The immune response to HBsAg provides the basis for immunity against HBV, and HBsAg is the main component of HepB.
