Concern over Covid-19 cases due to community transmission

Meanwhile, public health authorities are concerned about the number of Covid-19 cases detected in the last week which were as a result of community transmission, along with increased numbers of hospitalisations, the chief executive of the HSE has said.

Speaking on RTÉ's Morning Ireland programme, Paul Reid said the average number of cases per day for the last week is 246, up 39% over seven days.

He said 39% of cases emerging are from the community, not as a result of outbreaks or from close contacts.

Mr Reid also said there are now 77 people with Covid-19 in hospital, up from 23 last week.

He said ICU admissions have increased from six to 14 in the last week.

Mr Reid said that a suite of very basic measures can make a real difference, as he called for people to reduce contacts at home and in public settings to prevent spread of the virus.

He said that we are at an important crossroads and no one wants to go backwards as he appealed to everyone to take the public health messages seriously.

Mr Reid said that the public experts have identified that spread occurs where people meet, including in pubs and restaurants.

He said that the growing number of cases of the virus are brought from the community back into the home and are highly transmissible, so places where people congregate at home and in public settings are a risk.

The HSE's chief said if six people meet, five people can get infected very quickly.

Case numbers in schools are low and testing shows that transmission rates between children and adults in schools is not a concern, Mr Reid said.

He said there has been more school children and adults coming forward with symptoms, but not testing positive.

The impact has been limited to closing a pod or a classroom if a case emerges, never a school, he said.

Mr Reid said that the first few weeks of schools reopening are challenging, but overall it has been managed really well, with the vast majority of tests returned in 24 hours.

Consultant calls on Govt to address ICU capacity

A consultant in emergency medicine at Sligo Hospital has said it is time to address the lack of critical care bed capacity in hospitals rather than seek to reassure people that there is not a problem.

Speaking on the same programme, Dr Fergal Hickey said that at the start of the pandemic every bit of capacity was used for Covid-19, along with a drop in attendances at hospital emergency departments.

This has now ended as the system returned to pre-Covid operations.

He expressed concern about the lack of critical care beds available if there is a surge in hospitalisations as a result of the Covid-19 virus.

Dr Hickey said that the 2009 Prospectus Report on Excellence in Critical Care stated there was then 289 beds in critical care.

It recommended that by 2010 that 418 beds would be required and by 2020 to have 579.

Dr Hickey said this shows that long before the pandemic the country had insufficient capacity in ICU.

There are now 281 ICU beds in the system.

Dr Hickey said that recovery areas in hospital theatres and private capacity can be used for ICU, but the reality is we are short of critical care capacity.

"We need to do something more dramatic than making small incremental improvements from time to time," said Dr Hickey.
