About 3.4 million additional cases of Covid were identified during the week of July 12 to 18, 12% more than the previous week, she said.

57,000 deaths from Covid per week


At this rate, the cumulative number of reported cases (since the start of the pandemic) worldwide is expected to exceed 200 million in the next three weeks,
