Who has been infected with COVID-19 and why?

Posted on: 08 June 2020

A research project at Trinity is finding out who has been infected with COVID-19 amongst our older population, and more importantly why.

Researchers are measuring virus specific antibody levels and exploring what risk factors are associated with the disease, including analysing how the immune system has been utilised by this group.

Lead researcher, Dr Nollaig Bourke, Assistant Professor in Medical Gerontology and her team from the School of Medicine and the Trinity Translational Medical Institute (TTMI) are investigating the ‘who’ and ‘why’ of COVID-19 in older people in Ireland. They will investigate which participants of the Irish Longitudinal Study on Ageing (TILDA) were infected with the disease.

Dr Bourke’s research has been funded by the recent ‘COVID-19 Rapid Response Call’ research initiative by the Health Research Board and the Irish Research Council.

Dr Nollaig Bourke said:

Older people in Ireland have been disproportionally affected by COVID-19, so it is really important that we have accurate national rates of infection in this population (including asymptomatic individuals).

It is also very important that we understand who got sick and why, so by doing our proposed in-depth research into risk factors associated with COVID-19 disease in older people in Ireland, including detailed analysis of their immune system, we will potentially be able to explain why someone might be more likely to experience severe COVID-19 disease. This would potentially help us identify high risk individuals, as well as reveal what parts of the immune system would be best to target therapeutically in individuals.
