The coronavirus epidemic in the United Kingdom is showing signs of slowing and antibody tests could be ready in days, Neil Ferguson, a professor of mathematical biology at Imperial College London, said on Monday.
"We think the epidemic is just about slowing in the UK right now," Ferguson told BBC radio.
He said a third or even 40% of people do not get any symptoms. He said perhaps 2% to 3% of the United Kingdom's population had been infected.
But Junio Health Minister Helen Whately said she could not say when the antibody tests would arrive telling BBC radio: "I am not going to confirm when that's going to arrive."
