The latest on the coronavirus pandemic

The top health official for Seattle and King County, Washington, has warned that the drop in new coronavirus cases in their community seems to be leveling off again.

Duchin said people should not become cavalier about public gatherings because the virus can still be spread easily.

“In the last two weeks, we've had almost 200 business identified as having one or more people with Covid-19 working while contagious,” he said

Although the daily count of new Covid-19 cases in King County has fallen since peaking a month ago, the seven-day rolling average of new cases has remained in triple-digits since June 27. And Duchin said they are not expecting better news in the next few months.

“We expect Covid-19 to get worse in the fall and winter and people to spend more time indoors," he said. 

Just over a week after announcing the famed Kentucky Derby would allow fans in the stands to witness the 146th edition, organizers have changed their minds. The rescheduled Run for the Roses will now be held without spectators.

Churchill Downs originally said it would allow 14% capacity at the racetrack (some 23,000 fans) for the Sept. 5 Triple Crown race.

“The Kentucky Derby is a time-honored American tradition which has always been about bringing people together. However, the health and safety of our team, fans and participants is our highest concern," the Churchill Downs Friday announcement said.

“We deeply regret the disappointment this will bring to our loyal fans.”

Kentucky’s governor Andy Beshear supported the decision saying, “The virus is still aggressively spreading in Kentucky, and the White House has announced that Jefferson County and the City of Louisville are in a ‘red zone’ based on increases in cases … I applaud Churchill Downs for continuing to monitor the virus and for making the right and responsible decision.”

The US Centers for Disease Control and Prevention updated its school guidance Friday. The update adds more details to inform administrators’ decisions about opening schools and limit risk, according to CDC Director Dr. Robert Redfield. 

Redfield said the updated guidance comes out of discussions the CDC has been having with districts about how to best operate during a pandemic.

The updated guidelines encourage schools to work closely with local and public health leaders if there is an infected person on campus. Rather than shut everything down immediately for a long period of time, the guidelines said one option is an initial short-term class suspension and cancelation of events and after school activities, so that public health leaders can get the time they need to determine how widespread the infections are.

When schools are using a pod system, keeping certain students together, administrators may only need to close certain parts of the building where an infected person had been. If local health officials recommend against closing the building, school leaders should thoroughly clean that area.

The decision to suspend school altogether should be made on a case-by-case basis using the most up-to-date information about the pandemic, according to the guidelines, taking into account local case counts and the degree of ongoing transmission in the community.

More details: Schools are encouraged to “regularly” and “transparently” communicate with staff, teachers, students and families, including about mental health support services available at the school, the CDC said. Sharing facts will “counter the spread of misinformation and mitigate fear,” the guidelines said.

Schools should offer remote counseling and ensure the continuity of mental health services. Schools should also encourage students that feel overwhelmed and want to harm themselves or others to call 911 or the National Suicide Prevention Lifeline.

New York City has 19,007 confirmed coronavirus deaths and 4,634 probable coronavirus deaths as of Aug. 19, according to the most recent data on the city website.

The New York City Health Department defines probable deaths as people who did not have a positive Covid-19 laboratory test, but their death certificate lists as the cause of death “Covid-19” or an equivalent.

The total number of confirmed coronavirus deaths and probable coronavirus deaths in New York City is 23,641.

More data: There have been 227,927 coronavirus cases in the city and 56,862 people have been hospitalized, according to the city.

The data is from the New York City Health Department and was updated on Aug. 21 at 1 p.m., according to the website.

The University of Iowa is discontinuing four sports programs at the conclusion of the 2020-21 academic year.

The school cited the financial toll of the coronavirus pandemic as the reason for shutting down men’s gymnastics, men’s and women’s swimming and diving, and men’s tennis.

Existing scholarships will be honored through graduation as long as the student-athlete decides to remain at Iowa. Athletes in those sports will have the opportunity to compete in their upcoming 2020-21 seasons, but only if the circumstances surrounding Covid-19 permit before the sports are discontinued. 

Some context: Iowa is the latest high-profile university to cancel sports programs due to the coronavirus pandemic.

Last month, Stanford University cut 11 varsity sports programs including field hockey, synchronized swimming, men's volleyball and wrestling.

Arkansas is seeing an uptick in active cases of coronavirus, Gov. Asa Hutchinson said.

The state is reporting an increase of 887 cases of coronavirus and 22 deaths within the past 24 hours, Hutchinson said during a news conference today.

The governor said this is the largest number of deaths recorded since the pandemic began, and the fourth highest day of Covid-19 cases in the state, Hutchinson said.

The governor reminded residents that “we are not back to normal” and urged them to remain vigilant.

By the numbers: Arkansas has reported 55,652 total cases of coronavirus and 663 deaths since the pandemic started, according to Hutchinson. 

To note: These numbers were released by the Arkansas Department of Health and may not line up exactly in real time with CNN’s database drawn from Johns Hopkins University and the Covid Tracking Project.

New Hampshire Gov. Chris Sununu tweeted Friday that effective immediately, all restaurants in the state can go to 100% capacity for indoor dining. 

Tables will still be required to be six feet apart, and all other public health guidelines remain in effect, Sununu said.

Paraguay will institute a social quarantine in the country’s capital Asunción and its central region on Monday due to the increase of Covid-19 cases in the country, Health Minister Julio Mazzoleni announced on Friday. 

The social quarantine will be accompanied with restricted movement for the population during the night, limited long distance transport during the weekends as well as a ban on the sale of alcoholic beverages, the health ministry said in a statement on Friday. 

Physical activities will only be allowed on an individual basis, according to the statement. 

Mazzoleni said the measures were created to limit community activities where most of the transmission happens. 

“The pandemic will continue, but we need to stop the speed of transmission and stabilize the number of cases,” Mazzoleni said. 

As of Friday afternoon, the country reported a total of 11,817 Covid-19 cases and 170 deaths. 

The latest numbers: The number of deaths from coronavirus in Paraguay has more than doubled in 10 days, according to figures released by the country's health ministry. The total number of cases has risen by nearly 25% during this same period.

At least 36 students at Purdue University in Indiana were suspended this week after attending an off-campus party that violated the school’s social distancing rules.

The number of students suspended was confirmed by Tim Doty, the school's director of public information and issues management.

Doty said the students "may appeal the interim suspension, and the ultimate sanctioning decision will be made later after a full hearing process."

"The University will move that process forward expeditiously,” he said.

Meanwhile, Dr. Katie Sermersheim, associate vice provost and the dean of students, said the school has been "clear and consistent" in its messaging to students

Sermersheim said the university is asking to put on hold large gatherings in confined spaces for now, and that the university is calling upon its entire community of faculty, staff, and students to work together to "meet our collective health responsibilities."

Earlier this week, Purdue said in a news release that it was adding violation of the Protect Purdue Plan to its code of conduct regulations — meaning that students who violate the code could be subject to disciplinary action.

"If you don’t abide by rules, there is no place for you here,” Sermersheim said. 

Purdue announced its plan Friday for continued surveillance and testing of its nearly 40,000 students. According to the plan, all on-campus employees must undergo required weekly testing and random testing will take place for all students throughout the semester.

Classes are scheduled to begin on Monday.
