US deaths from the coronavirus pandemic have exceeded 160,000, nearly a quarter of the world's total, according to a Reuters tally.
It comes as the country debates whether schools are ready to reopen their doors in the coming weeks.
The country with the most coronavirus cases, the US recorded 160,003 deaths and 4.91 million cases.
Coronavirus deaths are rising in 23 states and cases in 20 states, according to a Reuters analysis of data the past two weeks compared with the prior two weeks.
On a per-capita basis, the US ranks 10th highest in the world for both cases and deaths.
There has been an increase of 10,000 deaths in nine days in the country.
Many of the new deaths have come from California, Florida and Texas, the top three US states for total cases.
While infections appear to be declining in those states, new outbreaks are emerging coast to coast.
White House coronavirus task force coordinator, Dr Deborah Birx, warned that Boston, Chicago, Detroit and Washington could face outbreaks due to increases in the percentage of coronavirus tests coming back positive.
Meanwhile, US officials, teachers’ unions, parents and students battle over how to reopen schools safely.
US President Donald Trump has urged states to resume in-person classes, saying the virus "will go away like things go away", but health officials have told states with rising counts to be on guard.
Nearly 300,000 US residents could be dead from Covid-19 by 1 December, University of Washington health experts forecast on Thursday, although they said 70,000 lives could be saved if Americans were scrupulous about wearing masks.
