The Galway City Central Local Electoral Area has the highest 14-day incidence of Covid-19 in the country with 767.7 cases per 100,000 people in the two weeks to last Monday, 1 March.
This is 3.8 times higher than the national average, which was 201.2 cases per 100,000 people on that date.
However, Galway city's high disease incidence rate still represents a very significant improvement compared with the previous Monday, when it was as high 1,300 cases per 100,000 people following a rapid increase that occurred in the preceding two weeks.
It is understood that the large student-linked outbreak in the city that went on to infect more than 200 households and 440 people, highlighted this week by the Director of Public Health in the region, was a key driver of that surge in cases in Galway City Central.
The second highest 14-day incidence of Covid-19 in the two weeks to 1 March was recorded in the Limerick City East Local Electoral Area with 608.3 cases per 100,000 people.
This was followed by the Longford Local Electoral Area in third place, where 579.6 people per 100,000 were infected during the same two-week period.
The disease incidence rate in both Limerick City East and Longford has gone up in each of the past two weeks.
The fourth highest disease incidence in the country was 523.5 cases per 100,000 people, recorded in the Ballymun-Finglas Local Electoral Area in Dublin.
This is followed in fifth place by Birr in Co Offaly where 498.5 people per 100,000 have been infected with Covid-19 in the fourteen days up to last Monday.
