A leaked internal memo from the Federal Emergency Management Agency has reportedly revealed a near-17 percent spike in coronavirus-related deaths inside the United States last week. ABC News obtained the memo that showed the trend in new deaths has shot way up since the start of September. It said that 5,906 coronavirus-related deaths were recorded in the U.S. from Sept. 9-15, which represents a 16.6 percent increase compared with the seven days prior. That figure comes despite 261,204 new cases of COVID-19 being confirmed in the same period, which is a 0.7 percent decrease from the previous week. Officials have found that coronavirus deaths are a lagging indicator and rise in the weeks after cases surge.
