R number – Covid-19

The Department of Health has published the current Covid-19 reproduction number (R).

The current estimate of R is 0.5 – 0.9 enabling the Executive decision today to ease some further restrictions. 

As of 9 June, the seven-day rolling average of new cases is 8. 

It is important to model the COVID-19 epidemic in Northern Ireland in order to plan the delivery of Health and Social Care services and to inform decision making with regard to social distancing and other restrictions.    

Central to this modelling is estimating the Reproduction Number (R).  R is the number of individuals who, on average, will be infected by a single infected person.    

There are different ways of calculating R and a number of different values for R each day are produced. That is why the number is being published in the form of banding.

The Executive has indicated that keeping R below 1 is a key objective as we move forward in the epidemic.

Notes to editors: 

1. R is not the only factor which will influence decisions about social distancing and other restrictions.  It is also necessary to consider the number of cases of COVID-19 and other indicators of the activity of the epidemic, in addition to the benefits which would come from relaxing restrictions.
