In a video posted on Twitter on Monday last, Dr. Glynn said the proportion of cases linked to the variant had increased rapidly over the last four weeks, from 5 percent of cases in early June to around 70 percent of cases currently.
“So far, some parts of the country have been more affected than others, including Donegal, Waterford and Dublin, but we are also seeing high or increasing incidence in Sligo, Limerick, Roscommon and Meath,” he said.
Roscommon currently has the eighth highest incidence rate of Covid-19 in the country, and between July 5th and July 11th, 51 cases of the disease had been identified in the county.
Dr. Glynn added that while hospitalisations remain low, there had been a “small but concerning increase” in the past week.
“This will be monitored in the weeks closely in the weeks ahead,” he said.
Highlighting recent cases where recipients of a single vaccine dose had been infected by the Delta variant, the Deputy CMO said it was important that everyone gets fully vaccinated as quickly as possible and that Public Health guidelines continue to be adhered to.
