The coronavirus pandemic caused nearly 300,000 deaths in the United States through early October, federal researchers said on Tuesday. The new tally includes not only deaths known to have been directly caused by the coronavirus, but also roughly 100,000 fatalities that are indirectly related and would not have occurred if not for the virus. The study, published by the Centers for Disease Control and Prevention, is an attempt to measure "excess deaths" " deaths from all causes that statistically exceed those normally occurring in a certain time period. The analysis highlights two disturbing trends. The researchers discovered a high percentage of excess deaths in an unexpected group: young adults in the prime of life. And the coronavirus has greatly raised deaths over all among people of color. Although the pandemic has mostly killed older Americans, the greatest percentage increase in excess deaths has occurred among adults ages 25 to 44, the analysis found. While the number of deaths among adults ages 45 to 64 increased by 15 percent, and by 24 percent among those ages 65 to 74, deaths increased 26.5 percent among those in their mid-20s to mid-40s, a group that includes millennials. People of color also had large percentage increases in excess deaths. Hispanics experienced a 54 percent increase, while Black people saw a 33 percent rise. Deaths were 29 percent above average for American Indians or Alaska Native people, and 37 percent above average for those of Asian descent.
