Coronavirus latest: Ohio reports highest number of cases since July
The governor urged residents to be vigilant as Labor Day approaches.
A pandemic of the novel coronavirus has now killed more than 852,000 people worldwide.
Over 25.5 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 184,270 deaths.
California has the most cases of any U.S. state, with more than 713,000 people diagnosed, according to Johns Hopkins data. California is followed by Texas and Florida, with over 633,000 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.

US case count tops 6 million
There were 33,888 new cases of COVID-19 identified in the United States on Monday, bringing the country’s cumulative total soaring past 6 million, according to a real-time count kept by Johns Hopkins University.
Monday’s tally is far below the country's record set on July 16, when 77,255 new cases were identified in a 24-hour reporting period.
An additional 595 coronavirus-related deaths were also recorded Monday. The latest daily death toll is well under the record 2,666 new fatalities that were reported on April 17.
A total of 6,031,013 people in the United States have been diagnosed with COVID-19 since the pandemic began, and at least 183,598 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 by substantial amounts in week-over-week comparisons, according to an internal memo from the Federal Emergency Management Agency obtained by ABC News last week.
Start of in-person school delayed in NYC
The start of in-person learning in New York City public schools has been delayed to Sept. 21, Mayor Bill de Blasio announced Tuesday.
The district's blended-learning plan was scheduled to begin on Sept. 10.
"Teachers who usually get two days of professional development at the beginning of the school year will now get nine," schools Chancellor Richard Carranza said. "We've heard from everyone in our schools that have said we need some more time."
In averting a strike authorization vote by the United Federation of Teachers later Tuesday, de Blasio agreed to delay the start of school to Sept. 16 for all-remote instruction. In-person learning, which is limited to a few days per week, will begin Sept. 21.
The mayor also announced expanded testing for teachers, a significant concession to the United Federation of Teachers.
