Coronavirus news: University imposes quarantine for all students

In New York City -- once the U.S. epicenter of the pandemic -- indoor dining can resume on Sept. 30 at a 25% capacity, New York Gov. Andrew Cuomo announced Wednesday.

Tables must be spaced 6 feet apart, Cuomo said, and at least one diner in each party must leave contact information.

The governor asked New Yorkers to help report any restaurants that violate the 25% capacity rule.

If there is a spike in infection rate, the city can "hit the emergency pause button," Cuomo said.

If there is no rise in infection rate, "we can always reassess the guidelines and go from 25% to 50%," he said.

Nov. 1 has been set as the benchmark date for upping indoor capacity to 50%, he said.

The Department of Health and Human Services will allow licensed pharmacists to administer COVID-19 vaccines to children ages 3 and up, when or if a vaccine is made available, Surgeon General Jerome Adams announced Wednesday.

In August, the Health and Human Services Department said pharmacists would be permitted to provide routine childhood vaccinations amid concerns that kids were missing out on visits to their doctors during the pandemic.

But the American Academy of Pediatrics called that decision "incredibly misguided," saying children would not get the same level of care from a pharmacist that they would from pediatricians. The American Academy of Pediatrics stressed that doctors' offices are open and safe.

Miami University in Ohio reported 159 new cases of the coronavirus over the Labor Day weekend, bringing the university's total number of cases to 1,037 in the last two weeks, according to a school dashboard.

Over the long weekend, six Miami University students were cited for breaking the city’s ordinance against large gatherings, ABC Cincinnati affiliate WCPO reported.

The students told police they tested positive for COVID-19 and were supposed to be quarantining, WCPO reported.

No trick-or-treating is allowed this Halloween in Los Angeles County due to the pandemic, ABC Los Angeles station KABC reported

The health department said it's too difficult to maintain social distancing with door-to-door trick-or-treating.

Parties, haunted houses and "trunk or treating" -- when kids go from car to car instead of house to house -- are also not allowed.

Car parades, dressing up houses and Halloween-themed meals at outdoor restaurants are permitted, the Department of Health said.

California has the most coronavirus cases of any state in the U.S., with over 745,000 people diagnosed, according to Johns Hopkins University data.
