The World Health Organization (WHO) reported the largest single-day increase of coronavirus cases on Sunday, June 21, with 183,0020 new cases reported in just 24 hours—the majority of which were identified in the Americas. The largest portion of new cases was reported by Brazil (54,771,) followed by the United States (36,617), and India (15,413). The global total number of cases has just surpassed nine million, according to Reuters. While the U.S. has seen a shift in the demographics and regions most affected by the coronavirus, the country as a whole is seeing a rise in new cases. However, according to The New York Times, overall deaths from coronavirus have dropped by over 40 percent. While Brazil’s most recent one-day death toll was over a thousand, the U.S. reported less than 600 for the same 24-hour period. According to CNN, “Many experts believe the number of cases [in Brazil] could surpass the United States and that Brazil may soon become the country worst hit by the virus.“ae0fcc31ae342fd3a1346ebb1f342fcb RELATED: For more up-to-date information, sign up for our daily newsletter.
