“The 14-day incidence rate has increased from 108 per 100,000 last Sunday to 150 per 100,000 today, which represents a 39% increase.
“All of the important indicators of the disease are deteriorating. For example, there has been a consistent increase in test positivity over the past week."
He added: "The test positivity rate up to midnight Friday 9th October was 6.2%, which has more than doubled in less than a fortnight.
“Case numbers are growing across all age groups and throughout the country.”
Dr Ronan Glynn, Deputy Chief Medical Officer, said: “In the past 24 hours, there have been 35 new admissions of laboratory-confirmed cases to hospital and four new admissions to ICU.
"There are now 199 people in hospital and 31 in ICU. Every age group, location and household needs to act now, limit your contacts and stop the disease in its tracks.”
