Coronavirus latest: University reports 90% jump in cases on campus
The University of Mississippi confirmed 223 new cases over the past seven days.
A pandemic of the novel coronavirus has now killed more than 857,000 people worldwide.
Over 25.7 million people across the globe have been diagnosed with COVID-19, the disease caused by the new respiratory virus, according to data compiled by the Center for Systems Science and Engineering at Johns Hopkins University. The criteria for diagnosis -- through clinical means or a lab test -- has varied from country-to-country. Still, the actual numbers are believed to be much higher due to testing shortages, many unreported cases and suspicions that some national governments are hiding or downplaying the scope of their outbreaks.
Since the first cases were detected in China in December, the virus has rapidly spread to every continent except Antarctica.
The United States is the worst-affected country, with more than 6 million diagnosed cases and at least 184,689 deaths.
California has the most cases of any U.S. state, with more than 715,000 people diagnosed, according to Johns Hopkins data. California is followed by Texas and Florida, with over 637,000 cases and over 631,000 cases respectively.
Nearly 170 vaccine candidates for COVID-19 are being tracked by the World Health Organization, six of which are in crucial phase three trials.

16 US states and territories are in an upward trajectory, FEMA memo shows
An internal memo from the Federal Emergency Management Agency obtained by ABC News on Tuesday evening shows that 16 U.S. states and territories are in an upward trajectory of new COVID-19 cases, while 10 jurisdictions are at a plateau and 30 are going down.
Nationwide, the numbers of new COVID-19 cases and new deaths have both decreased in week-over-week comparisons. There were 288,876 new cases confirmed during the period of Aug. 25-31, a 1.9% decrease from the previous seven-day period. There were also 6,433 new fatalities recorded, marking a 5.1% decrease compared with the previous week, according to the memo.
Meanwhile, the national positivity rate for COVID-19 tests ticked downward slightly to 5.2%, compared with 5.5% for the prior seven-day period, the memo shows.
Indiana has the ninth-highest case rate in the country, with more than 100 new cases per 100,000 population last week. The state’s positivity rate for COVID-19 tests is nearing 10% amid a rapid case rise linked to university towns. More than half of all counties in Indiana have ongoing community transmission, of which 8% have high levels of community transmission, according to the memo.
South Dakota has the highest positivity rate for COVID-19 tests of any U.S. state, at greater than 15%, according to the memo, which noted that “testing across the state is broadly insufficient.” Approximately 30% of all counties in South Dakota have ongoing community transmission and 21% have high levels of community transmission, the memo shows.
In Ohio, the majority of new cases are among Miami University student-athletes and the people they have come in contact with since Aug. 17. As of Aug. 27, there have been 215 reported cases among students and two reported cases among employees at the public research university in Oxford, Ohio, according to the memo.

US reports over 1,000 new deaths in a single day
An additional 1,067 coronavirus-related deaths were recorded in the United States on Tuesday, a nearly twofold increase from the previous day, according to a real-time count kept by Johns Hopkins University.
It's the first time in almost a week that the nation has reported more than 1,000 new deaths from COVID-19 in a single day. However, Tuesday’s death toll is still under the country’s record set on April 17, when there were 2,666 new fatalities in a 24-hour-reporting period.
There were also 43,253 new cases of COVID-19 identified in the United States on Tuesday. The daily tally is well below the record 77,255 new cases reported on July 16.
A total of 6,075,652 people in the United States have been diagnosed with COVID-19 since the pandemic began, and at least 184,689 of them have died, according to Johns Hopkins. The cases include people from all 50 U.S. states, Washington, D.C. and other U.S. territories as well as repatriated citizens.
By May 20, all U.S. states had begun lifting stay-at-home orders and other restrictions put in place to curb the spread of the novel coronavirus. The day-to-day increase in the country's cases then hovered around 20,000 for a couple of weeks before shooting back up and crossing 70,000 for the first time in mid-July.
However, the numbers of new COVID-19 cases and new deaths in the United States have both decreased in week-over-week comparisons, according to an internal memo from the Federal Emergency Management Agency obtained by ABC News Tuesday night.
Greece reports 1st case in overcrowded migrant camp
Greece announced Wednesday it is imposing a two-week lockdown on the Moria migrant camp on the island of Lesbos, after a refugee there tested positive for COVID-19.
The 40-year-old Somali man had left the camp on July 17 after being granted refugee status and a residence permit to live in Greece. However, for unknown reasons, he had returned in recent days and had been living in a tent outside the camp fence. He has since tested positive for the virus and remains hospitalized on the island, according to a press release from the Greek Ministry of Migration and Asylum.
It’s the first confirmed case of COVID-19 in the overcrowded camp, a space designed for 2,200 people but now, according to the United Nations, houses over 18,000.
The ministry said entry and exit would be prohibited at the camp until Sept. 15, while the presence of security forces has been increased around the structure to enforce the 14-day quarantine. Meanwhile, authorities are working to trace the man’s contacts and a new health unit will be put in place at the camp to isolate and monitor suspected cases, according to the ministry.
