Ireland may be past the peak of its fourth wave of Covid-19 driven by the Delta variant, according to the National Public Health Emergency Team (Nphet).

Professor Philip Nolan, who chairs the Nphet Epidemiological Modelling Advisory Group, said the country is slightly ahead of Nphet’s optimistic assumption of how the disease would progress.

It was "not unreasonable" to believe that the country was "just past the peak of infection" and case numbers should decline "from here on in", he said.

The chief medical officer (CMO) meanwhile said he does not believe significant restrictions will be reimposed based on current health data.

Dr Tony Holohan said he is “optimistic” about the trajectory of the disease, and said the country is on course to meet criteria that will allow the vast majority of restrictions to be lifted next month.

New variant

Public health experts set out a series of criteria to Government that should be met before the country can move out of restrictions on October 22nd. They include a target of vaccinating 90 per cent of the population over the age of 16, and passing the peak of the Delta variant.

Appearing before the Oireachtas health committee, Dr Holohan said Nphet can “never absolutely” rule out further measures to curb the spread of Covid-19.

“We don’t think we’re going to be in a situation where some of the significant restrictions that had to be imposed in the Irish population are likely to be necessary on the basis of anything that we see in front of us right now,” he added.

“In broad terms we are optimistic about the trajectory of the disease at this point in time.

“The likelihood that over the course of the coming weeks, the important criteria that we set out in our last advice to Government, that needs to be satisfied before we think we’re able to move on from the range of measures that are still in place being eased, we think we are a short number of weeks away from that.

“We don’t see anything at this point in time emerging in the international scene, globally, by way of concern about a new variant.”

Prof Nolan said there had been 100,000 cases detected between June 20th and Tuesday (September 14th).

“If we take the most optimistic scenario we’re currently looking at, which is not unreasonable, we’re just past the peak of infection and case numbers should decline from here on in, and that may be happening, given the data we have now,” Prof Nolan told the committee.

School outbreaks

Dr Holohan said there will be changes to self-isolation rules for asymptomatic close contacts for schoolchildren and wider society.

He confirmed there are currently 12,000 schoolchildren self-isolating around the country.

Recent data shows that up to last Saturday, there were 40 outbreaks in schools and 191 linked cases.

Dr Holohan said he hopes changes to self-isolation rules can be made soon when health experts have had time to monitor the impact of schools reopening.

The committee also heard that high rates of infection are leading to outbreaks in nursing homes.

Dr Holohan said this was “the force of infection”.

He warned that as vaccines are not 100 per cent effective, there will always be some people vulnerable to the disease.

He also said that although there are high levels of vaccination among staff at nursing homes, there is an issue around agency staff.

“We do believe that there has been a challenge in some nursing homes in maintaining high levels of staff, particularly perhaps among those people who work in nursing homes, but who actually come from agencies,” he added.

He said the HSE is trying to avoid deploying staff who are not fully vaccinated in nursing homes.

Data shows that from June 27th to September 11th, there were seven outbreaks in community hospitals and long stay units and 51 outbreaks in nursing homes.

 

Across those outbreaks, there were 896 cases detected, and 31 people admitted to hospital, with 31 dying from the disease.

Prof Karina Butler, chairwoman of the National Immunisation Advisory Committee (Niac), said that people living in nursing homes and those over the age of 80 will be offered a booster jab.

She said recent data from Israel and Public Health England shows that their immunity wanes more quickly.

“Although we see a creep up in the amount of infections, the impact has been very, very different in the vaccinated population versus the unvaccinated,” Prof Butler said.

“So for the elderly who are fully vaccinated, and most of them are, when they get infected, most of them have a milder disease than they would have had, say, last January.”

She said plans to roll out booster jabs are being put in place by the HSE.

Prof Butler also said she hopes all staff in nursing homes are vaccinated, but the approach of mandatory vaccination has “never been a good thing” and has “always been a last resort”.
