The latest on the coronavirus pandemic

There are 36 coronavirus cases linked to a Kentucky football team's practice in a weight room, Gov. Andy Beshear said during a news conference Friday.

Beshear said 18 players, three coaches and 15 family members have tested positive following the practice.

The governor would not say where the cases occurred.

The state reported the third highest single-day coronavirus case increase on Friday, with 531, Beshear added.

There are now a total 21,605 cases statewide, the governor said.

Eight new deaths were reported Friday for a total of 653 coronavirus deaths statewide, the governor said.

People in Miami, Florida, will no longer get a warning when they fail to wear a mask in public starting Monday. 

Mayor Francis Suarez said the new order will require a fine for the first offense of the city’s mask order. The fine starts at $50 and increases with every additional offense. 

At the same time, Suarez said the city does not intend to return to a full stay-at-home order – at least not yet.

"We are consulting with Miami-Dade County and with all the cities,” Suarez said.

Texas reported 174 new Covid-19 related deaths on Friday, a record single day high, surpassing Thursday's record of 129 deaths in a single day. 

The total number of Covid-19 related deaths in the state is now 3,735.

Texas reported 10,256 new COVID-19 cases on Friday, bringing the total number of cases in the state to 307,572 .

To eliminate the spread of the novel coronavirus, governments should synchronize lockdowns, a new model shows.

The model, published Friday in the journal Science, found that when intermittent lockdowns were synchronized across Europe, half as many lockdowns were needed to end community transmission all across the continent.

Nick Ruktanonchai, an infectious disease epidemiologist at the University of Southampton in the United Kingdom, ran 1,200 simulations. To create the models, Ruktanonchai and his team used data from mobile phones provided by Vodaphone and Google that can show contact rates between people, in combination with different intervention scenarios.

The details: When the team ran a scenario that synchronized four cycles of three-week long lockdowns in all the countries in Europe, Covid-19 spread was eliminated 90% of the times.

When the lockdowns weren’t synchronized, community spread of the disease was eliminated only 5% of the time. When lockdowns are lifted early or unevenly, people interact and the disease spreads. 

The authors argue this information is generalizable to other parts of the world, including the United States. They believe national governments should coordinate pandemic preparedness efforts moving forward.

Mississippi Gov. Tate Reeves said that unless coronavirus conditions change dramatically over the weekend, the state may add 11 counties to its mask requirement. 

Thirteen counties are already under the more restrictive order.

Reeves noted that state figures show an additional thousand Covid-19 cases a day in Mississippi for each of the past two days.

State Health Officer Dr. Thomas Dobbs said some hospitals are running out of intensive care space.

“Every resource is exhaustible,” Dobbs said, encouraging everyone to wear a mask in public. “I'm baffled that the simplest of solutions is the one that we refuse to broadly adopt.”

Despite the surge in the state, the governor says he is not yet inclined to require all Mississippi public schools to go to remote learning plans.

“We can't force every parent to homeschool their kids indefinitely,” said Reeves.

There were 237,743 new Covid-19 cases reported to the World Health Organization in the last 24 hours, according to a new situation report published Friday.

The total number of cases that have been reported to the WHO from around the globe is now 13,616,593.

The rise in newly reported cases sets another record for cases reported to the WHO within a 24-hour period. The previous record was set on Sunday with 230,370 new cases of Covid-19.

Friday's report also noted there were 5,682 additional Covid-19 deaths reported to the WHO in the past 24 hours, bringing the total number of deaths worldwide to 585,727.

To note: While these numbers are OK to report as an independent news item, CNN relies exclusively on Johns Hopkins University data for its coronavirus case and death counts.

In an order issued today, Broward County, Florida, is enacting a curfew for the entire county, including incorporate and unincorporated areas, to help mitigate the spread of Covid-19.

The curfew is effective immediately from 11 p.m. to 5 a.m. ET nightly through Aug. 1, the order said.

According to the order, during curfew, no persons shall make use of any street or sidewalk in Broward County.

The order also prohibits gatherings of more than 10 people.

Major League Baseball free agent Yasiel Puig says he has tested positive for Covid-19.

In a statement posted on social media Friday, the Cuban-born outfielder said he was currently asymptomatic and will remain in quarantine.

Some context:  On Friday, the MLB and Major League Baseball Players Association released the latest testing results as of July 16, in which six out of 10,548 samples came back positive for Covid-19.

Five of the positive tests were players, and one was a staff member. The MLB season is scheduled to resume on July 23. 

Watch:

Arkansas has reported 31,762 positive cases of coronavirus and 353 deaths, Dr. Nate Smith, Arkansas cabinet secretary for the Department of Health, said during a news conference on Friday.

That total includes an increase of 648 Covid-19 cases since Thursday. There have been 12 deaths reported from June 12 to June 24, Smith said.

Arkansas has conducted 5,861 Covid-19 tests, Smith added.

Former Arkansas governor and US Senator David Pryor, who tested positive for Covid-19, was released from the hospital and is in good health, Hutchinson said.
