There have been 2,399 new cases of Covid-19 reported by the Department of Health.

It is the highest daily total since 22 January 2021.

There are 473 people with Covid-19 in hospitals around the country, down 11 since yesterday. 74 of these patients are being treated in intensive care units, up one.

The five-day moving average of cases is 1,890.

Earlier, the National Public Health Emergency team told the Government that should the latest changes not have a sufficient effect on the profile of Covid-19, the re-imposition of public health restrictive measures may be warranted.

In its 12 pages of advice, NPHET said that the return to the workplace should continue to be phased and cautious.

It has also called for sector-specific guidance and protocols for hospitality, cultural and sporting events to be reviewed and strengthened where necessary.

"NPHET continues to recommend that all who can work from home should continue to do so," it advised.

It added that homeworking has played a very important role in containing the spread of Covid-19 throughout the duration of the pandemic.

It said that with the easing of social and economic restrictions, a majority of employees have already, or will need to return to the workplace on at least a partial basis over the coming months.

NPHET has repeated previous advice that with the Delta variant being highly transmissible, it is unlikely that vaccination alone, even at the high levels of vaccine coverage that Ireland now has achieved, will bring the effective reproduction number below 1, such that Ireland will achieve suppression of the disease.

As a result, during the autumn and winter, possibly in the face of high levels of infection, Ireland will remain dependent on public understanding and buy-in of the basic public health measures.
