Coronavirus latest: 5 states removed from New York travel advisory list

Testing at the University of Miami showed 141 people, most of them students, tested positive for COVID-19, according to data from the school.

There were 2,627 students, faculty, staff and university vendors were tested between Aug. 16 and Aug. 22, the school posted on its new COVID-19 dashboard.

There were an additional 59 students placed in isolation and another 98 quarantined because of potential exposure to someone who was infected.

One member of the university staff was hospitalized.

There are 158 people who have been asked to quarantine in Seminole County, Florida, since schools opened for in-person learning last week.

The Seminole County School District opened schools on Aug. 17.

Nine schools in the district have people who are under quarantine -- the district has approximately 12 positive cases, according to public school officials.

Those in quarantine were switched to the remote learning platform until they are cleared to return to the schools, officials said.

New York Gov. Andrew Cuomo announced Tuesday that five states -- Alaska, Arizona, Delaware, Maryland and Montana -- have been removed from the Empire State's coronavirus travel advisory list, while the U.S. territory of Guam has been added.

The advisory mandates a 14-day self-quarantine for travelers arriving from areas "with significant community spread." That list now includes Alabama, Arkansas, California, Florida, Georgia, Guam, Hawaii, Iowa, Idaho, Illinois, Indiana, Kansas, Kentucky, Louisiana, Minnesota, Missouri, Mississippi, North Carolina, North Dakota, Nebraska, Nevada, Oklahoma, Puerto Rico, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Virgin Islands and Wisconsin.

New York state has had a rate of positive COVID-19 tests below 1% for 18 straight days, according to Cuomo, who warned "this pandemic is not over" and urged residents to "stay vigilant and be careful."

"New Yorkers made enormous sacrifices to get our numbers as low as they are today, and we don't want to give up an inch of that hard-earned progress," Cuomo said at Tuesday's press briefing. "That's why these travel advisory precautions are so important -- we don't want people who travel to states with high community spread to bring the virus back here."

Face masks will be obligatory for children aged 6 and older while at schools in Spain's central capital.

Madrid's regional premier, Isabel Diaz Ayuso, announced the new measure at a press conference Tuesday, while presenting a strategy for the safe return to schools amid the coronavirus pandemic. She said class sizes will also be reduced and thousands more teachers will be hired on a temporary basis.

Diaz Ayuso noted that, if Madrid's epidemiological situation improves, face masks will only be mandatory for students aged 11 and up. The region is planning for the staggered reopening of schools in September.

With over 405,000 diagnosed cases of COVID-19 so far, Spain has the highest case count of any country in Europe. The day-to-day increase of new cases has been steadily climbing since Spain emerged from a more than three-month national lockdown in late June.

Last week, Spain's head of health emergencies, Dr. Fernando Simon, warned that "things are not going well" regarding a recent spike of infections.

"Each day, we are seeing more and more transmission," Simon said.
