The Health Service Executive has reported "high" numbers attending Covid-19 test centres across the southeast region, as case numbers continue to rise nationally.

The southeast community healthcare team reminded people to book tests online as "walk-in" services are not available at the five centres in the region.

Testing is available at St Dympna's Hospital in Carlow town, the Hebron Industrial Estate in Kilkenny; Kilcohan in Waterford; Whitemills Industrial Park in Wexford; and Moyle Rovers GAA Centre outside Clonmel, on a seven-day basis, but must be booked online or the result of a referral by a GP.

"Numbers coming to these five centres operated by HSE/southeast community healthcare continue to be high," the HSE said in a statement, describing the public's response as "excellent" since testing started.

"The HSE is very grateful to its outstanding testing staff across counties Carlow, Kilkenny, South Tipperary, Waterford and Wexford for their hard work over the last year and a half of pandemic at pop-up facilities and the five permanent testing centres in the southeast," the HSE said in a statement.

Meanwhile, a local GP has described the situation as worrying.

Speaking on RTÉ's News at One, Dr Dermot Nolan of the Tramore Medical Centre in Co Wexford, said they had an average of seven Covid related calls a day to the practice a month ago, which had risen to 15 by last week and 23 today.

He said one of the worrying things they have seen is a "slight reluctance" in patients to get tested for Covid-19.

Dr Nolan said there are also symptomatic patients taking home antigen tests that are coming back negative and they are sending their children to school.

"This message hasn't really got through," Dr Nolan said. "Kids are attending schools with symptoms and it may be Covid, and that's the problem."

Anyone with symptoms such as a cough, fever, headache, sore throat, or blocked/runny nose has been advised again to isolate and get tested.
