“I hope we can turn the corner without re-imposing sanctions.
“If the current increase continues to be called 10,000 or more, which will have serious consequences, people will fall seriously ill and people will die.”

“If it is to be avoided, it will be a conscious effort by all of us to slow down the transmission.”
