In an optimistic scenario - 2500-3000 new infections per day will be reported by mid September, Up to 700 people could be in hospital, and as many as 130 people in ICU
In the most pessimistic of scenarios - there could be up to 12,500 covid infections per day.
Most likely - is that we will see highs of between 3000-5000 cases per day, while more than 750 covid patients may require hospital treatment.
Critical care beds may also be needed for between 150-250 people with the virus.
The CMO says the emergence of new variants is inevitable - but vaccines are likely to provide significant protection against them.
NPHET has said that mask wearing in certain setting will be required until at least the Spring of next year."
