The number of coronavirus infections around the world hit 13 million on Monday, according to a Reuters tally, climbing by a million in just five days.

The pandemic has now killed more than half a million people in six-and-a-half months, and World Health Organization (WHO) chief Tedros Adhanom Ghebreyesus said there would be no return to the “old normal” for the foreseeable future, especially if preventive measures were neglected.
