The rate of COVID-19 transmission has risen above a critical level that means the infection is growing exponentially, official figures show.

The last time the reproduction rate was above one was in early March.
It is understood that schools and universities are expected to cause a further increase in the spread of COVID-19.
Is it time to shut schools to push R rate down?
