Over 5,000 people have used a site which gives a personalised risk assessment for COVID-19.
COVID MedBot has been developed by Irish digital health start-up Akkure.
The free-to-use service says 86% of its traffic since its launch on Tuesday were first time visitors to the site.
The tool is available online, with the self-assessment being completed in 90 seconds.
The assessment has been taken in almost equal proportions by men and women, and by people in every county.
The company says it has also been taken by people in Europe, the UK and USA.
It provides personalised risk assessment and guidelines, which are in line with the HSE recommendations and leverage advice from the World Health Organisation (WHO) and the US Centres for Disease Control and Prevention (CDC).
The virtual service can also be accessed by patients, GPs and hospitals.
Dr Oran Rigby, founder of Akkure, said: "We are delighted that the self-assessment is something that has been used by some many people so quickly.
"The online assessment is free and crucially it can be taken many times as the risk evolves over time and takes only two or three minutes.
"We would encourage people to take the free assessment as often as they want, as more self-assessments will enrich the view and progression of COVID-19 providing insights to assist with surge planning and resource allocation."
The COVIDMedBot is updated based on an individual’s specific responses.
The risk assessment can be repeated as many times as a user wants with sequential consults.
