COVID-19 (Coronavirus) Pandemic

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 confirmed cases of COVID-19 around the world show there are approximately 6.9 million cases and around 400,500 deaths due to COVID-19, to date (8th June, 2020). 

Coronaviruses are a large family of viruses that circulate among animals including camels, cats and bats.  They can be spread from animals to humans.  Coronaviruses cause illness in humans ranging from the common cold to more severe respiratory (lung) diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).

The first cases of the new virus were identified in people working in a seafood and live animal market in Wuhan, China.  It is thought that humans picked up the virus from animals at the market. 

COVID-19 in Ireland

Ireland's first case of COVID-19 was confirmed on 29 February, 2020.  As of the 8th June, 2020 there were 25,207 confirmed cases of COVID-19 and 1,683 deaths due to COVID-19 in Ireland.  Here is a link to the daily reports by the Health Surveillance Protection Centre (HSPC) for the most recent COVID-19 data.

Ireland has advanced plans in place as part of its comprehensive preparedness to deal with public health emergencies such as COVID-19.  These plans have helped Ireland to respond to previous incidents such as Pandemic Influenza, SARS and MERS.  Ireland's response to COVID-19 is detailed on the Government's official website GOV.IE  

Most people who fall sick with COVID-19 will experience mild to moderate symptoms and recover without special treatment.  According to the Health Services Executive (HSE) the virus that causes COVID-19 is mainly transmitted through droplets generated when an infected person coughs, sneezes or exhales.  These droplets are too heavy to hang in the air, and quickly fall on floors or surfaces.  

You can be infected by breathing in the virus if you are within close proximity of someone who has COVID-19, or by touching a contaminated surface and then transferring the virus by touching your eyes, nose or mouth.  It can take up to 14 days for symptoms of COVID-19 to appear.  They can be similar to the symptoms of cold and flu and include a fever, a cough or shortness of breath.  

Covid-19 Data Hub

In response to the COVID-19 outbreak, the Central Statistics Office (CSO) in collaboration with Ordnance Survey Ireland (OSI), the Department of Housing, Planning & Local Government (DHPLG) and the All Island Research Observatory (AIRO) in Maynooth University, along with Esri Ireland as technical partners, rapidly developed a National Covid-19 Data Hub on the GeoHive platform.  GeoHive was identified as the States geospatial data platform in the Public Service Data Strategy 2019 – 2023.

For this particular action this work has been designated as the GeoHive COVID-19 Response Coordination Group, (GH-COVID-19-RCG).  The Group is part of the Irish Epidemiological Modelling Action Group (IEMAG).  The Office of the Chief Medical Officer (CMO), has formed the IEMAG, to monitor and model the outbreak of COVID-19 in Ireland.  The IEMAG report directly to the National Public Health Emergency Team (NPHET).

The National COVID-19 project partners use best practice methodologies and governance structures to ensure the appropriate overall management of the project and its data.  The Portal providing open access to up-to-date data on COVID-19 in Ireland, including datasets in linked-open-data format and visualisations, as well as other relevant information resources is available at DATA.GOV.IE/Blog, and all information is available at DATA.GOV.IE

The CSO has produced tables to provide summary information on the people who have died from COVID-19  or have been diagnosed with the virus.

For up to date statistics on the number of cases and deaths please see COVID-19 DASHBOARD.

SDG 3.3.1 Number of New HIV Infections was published by the HSE, HPSC in their Annual Epidemiological Report.  

Human Immunodeficiency Virus (HIV) is a virus that attacks cells that help the body fight infection, making a person more vulnerable to other infections and diseases. 
 
There were 523 people diagnosed with HIV in Ireland 2018.  Just over seven in ten of these people lived in the East region, based on the HSE area of residence.  Less than 2% of people who were diagnosed with HIV lived in the Midland or North-West regions.  See Table 2.5 and Figure 2.5.

SDG 3.3.2  Tuberculosis Incidence was published by the HSE, HPSC in their Annual Tuberculosis Epidemiological Report.

Tuberculosis (TB) is an infectious disease usually caused by Mycobacterium Tuberculosis (MTB) Bacteria.  TB is a preventable and curable disease that generally affects the lungs, but can also affect other parts of the body including the glands, the bones and rarely the brain.  Most infections show no symptoms, in which case it is known as latent tuberculosis. 
 
There were 267 TB notifications in Ireland in 2019.  Four in ten of these TB notifications were in the East region, (based on the HSE Area of Residence), while two in ten were in the South-East.  See Table 2.8 and Figure 2.7.

The number of TB cases notified in Ireland dropped from 420 in 2010 to 267 in 2019.  The population of Ireland rose between 2010 and 2019.  Therefore the rate of TB cases notified per 100,000 population also dropped, falling from 9.2 to 5.6.  See Table 2.9.

Show Table: 2.9 - SDG 3.3.2 Notified Cases of TB

About 41% of those with a notified case of TB in Ireland in 2019 were aged between 25-44 years while 24% were aged 65 years or over.  Very few children aged under 15 years had a notified case of TB.  Only 10 children aged under 10 years had a notified case of TB in 2019 while there were no cases for children aged 10-14 years.  See Table 2.10.

SDG 3.3.4 Hepatitis B Incidence was published by the HSE, HPSC in their Hepatitis B in Ireland Report.

Hepatitis B is a viral infection that infects the liver.  Hepatitis B is a major cause of serious liver disease such as cirrhosis and liver cancer, and affects millions of people worldwide.  In most people, a full course of vaccination prevents infection.
 
The number of cases of Hepatitis B in Ireland dropped from 639 to 546 between 2010 and 2019.  The rate of Hepatitis B in Ireland per 100,000 population dropped from 13.9 to 10.4 between 2010 and 2018.  The highest rate of Hepatitis B over this time period was in the East region, based on the classification by the Health Protection Surveillance Centre (HPSC).  In 2017, the rate of Hepatitis B per 100,000 population in the East was 20.1 compared with just 1.6 in the North-West.  See Table 2.13 and Figure 2.9.

SDG 3.3.5 Number of People Requiring Interventions Against Neglected Tropical Diseases was published by the United Nations Statistics Division (UNSD).  These data are classified as Tier 2 in the Tier Classification for Global SDG Indicators (See Background Notes), as they are not regularly produced by countries.

Neglected Tropical Diseases (NTDs) are a diverse group of communicable diseases that prevail in tropical and subtropical conditions and affect more than one billion people and cost developing economies billions of dollars every year.  Populations living in poverty, without adequate sanitation and in close contact with infectious vectors and domestic animals and livestock are those worst affected.

In each year between 2010 and 2015 there was either one case or zero cases of people in Ireland requiring interventions against a neglected tropical disease.  

In 2016, there were 20 people in Ireland who required an intervention against a neglected tropical diseases.  This number dropped to 10 in 2017 and to zero in 2018.  See Table 2.14.
