The COVID-19 pandemic is spreading fast across the U.S.
The country has been seeing more than 40 thousand new cases each day for the past 7 days.
According to Johns Hopkins University, the U.S. reported around 53-thousand cases on Wednesday, the most new cases in a single day so far.
South Korea is also seeing cluster infections pop up across the country.
Out of the 54 new cases of COVID-19 reported in South Korea on Thursday, 44 were transmitted locally.
That's the highest number of local transmissions in two weeks.
And 22 new cases-- which is half of the local transmissions-- came from the southwestern city of Gwangju, raising concerns over a surge in cases in the area.
"Infections are spreading to areas outside the capital such as Daejeon and Gwangju, centered on door-to-door sales companies and religious facilities. Only when preventive measures like wearing masks and keeping a safe distance are consistently followed, we can fundamentally prevent clusters of outbreaks caused by asymptomatic infections."
The World Health Organization says 60 percent of the total COVID-19 cases worldwide have been reported in the last month alone.
The WHO's Director-General on Wednesday expressed worries about countries easing their restrictions.
"We are concerned that some countries have not used all the tools at their disposal and have taken a fragmented approach. These countries face a long, hard road ahead."
The WHO said the number of new cases globally has been exceeding 160-thousand a day for the past week.
