A judge halted an executive order requiring schools to be open five days a week.
The global coronavirus pandemic has now killed more than 806,000 people worldwide, nearly a quarter of those in the U.S.
More 23.2 million people worldwide 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 actual numbers are believed to be much higher due to testing shortages, unreported cases and suspicions that some national governments are hiding or downplaying the scope of their outbreaks.
The United States is the worst-affected country, with more than 5.6 million diagnosed cases and at least 176,659 deaths.
New York Gov. Andrew Cuomo said the COVID-19 infection rate in the state was 0.66% as of Sunday, the lowest since the start of the pandemic.
"It is a great day," Cuomo said at Monday's press briefing, noting that the state has now had an infection rate under 1% for more than two weeks.
However, the western part of the state, including the Buffalo region, has seen an uptick in cases and the infection rate, he said.
The U.S. Environmental Protection Agency announced Monday that it has granted emergency authorization for the first antiviral surface coating approved for use to continuously protect against the virus that causes COVID-19 with a single application.
The product, SurfaceWise 2 from the Texas-based company Allied BioScience, is now approved for use by American Airlines, the Texas Methodist Health Group and at certain locations of the Texas-based clinics Total Orthopedics Sports & Spine.
"This is, I believe, a major game-changing announcement for our efforts to combat coronavirus and COVID19," EPA administrator Andrew Wheeler said on a call with reporters Monday morning.
While the product is intended to deactivate the virus on surfaces between routine cleanings for up to seven days, Wheeler said it’s not supposed to replace frequent cleaning with disinfectants, hand washing, wearing masks or social distancing. He also said that the EPA did not find any adverse health risks from coming in contact with the product on a surface, though the National Institutes of Health has found the main ingredient, quaternary ammonium, can be an irritant and exacerbate asthma.

The University of Hong Kong claims it has documented the world's first case of COVID-19 reinfection.
The university made the announcement in a press release Monday, revealing findings from its study of an "apparently young and healthy patient" who had a second episode of COVID-19 infection which was diagnosed more than four months after the first episode. A team of researchers showed that the genome sequence of the virus strain in the first episode of COVID-19 infection is "clearly different" from that of the virus strain found during the second episode of infection, according to the press release.
Last week, the World Health Organization said there were over 75,000 COVID-19 sequences identified and that they would need to see evidence of individuals who were infected by two different sequences in order to prove reinfection.
There are dozens of studies on COVID-19 immunity being conducted around the world. So far, WHO officials say they have learned that people do develop an immune response to the virus, but it's not completely clear yet how strong that response is and for how long it lasts.
"What we understand from the press release is that this 'may' be an example of reinfection," Dr. Maria van Kerkhove, WHO's COVID-19 technical lead and an infectious disease epidemiologist, said at Monday's news briefing in Geneva.
"It's very important we document this and in countries where sequencing can be done that would be very, very helpful," she added. "But we need to not jump to any conclusions, even if this is the first documented case of reinfection."

France’s national public health agency identified 4,897 new cases of COVID-19 on Sunday, the country’s highest day-to-day increase in infections since coming out of lockdown.
However, just one coronavirus-related fatality was recorded in the past 24 hours.
Since the start of the pandemic, France has reported 242,899 confirmed cases of COVID-19 with 30,513 deaths. The country is among the hardest-hit in Europe.
The positivity rate for COVID-19 tests in France increased from 2.8% on Aug. 18 to 3.6% on Aug. 24, according to the national public health agency.
