The coronavirus pandemic passed the 15-million case mark on Wednesday, with more than half of them in the United States and Latin America, according to an AFP tally.
The pandemic continues to accelerate, the data showed, and many countries are being forced to step up their prevention measures.
In less than five days, one million new cases have been recorded worldwide.
While in the past week, more than 230,000 cases have been reported daily on average. The number of known infections has doubled since June 11.
At least 15,007,291 total cases were recorded, with 617,603 deaths and 8,351,373 people reported to have recovered from the disease.
The US is the worst-affected country with 3,915,780 total cases, including 142,312 deaths — more than 460,000 new cases were recorded in one week, according to data from the Centers for Disease Control and Prevention (CDC), 10% more than the previous week.
Other signs of acceleration outside the US included several countries or territories recording record numbers of cases in recent days, such as Australia, with 502 new cases on Wednesday and a total approaching 13,000
Hong Kong saying it had 113 new COVID-19 infections on Wednesday — also a new record.
