Immune To COVID? New Study Suggests Why

New York, New Jersey and Connecticut will require travelers from states with surging cases of COVID-19 to quarantine for 14 days.

The governors of the three states announced the new rules Wednesday.

"All individuals traveling from states with significant community spread of COVID into NY, NJ, or CT must quarantine for 14 days," New York Gov. Andrew Cuomo said on Twitter. "This travel advisory is effective midnight tonight."

The quarantines will be based on infection rates, Cuomo said during a joint press conference. Travelers arriving from states with a positive test rate either higher than 10 per 100,000 residents or 10% of the total population will be required to quarantine.

As of Wednesday, the rule applies to Alabama, Arkansas, Arizona, Florida, North Carolina, South Carolina, Utah, Texas and Washington. Cuomo said the list of states under the quarantine order could change on a daily basis.

"We did a complete 180,” he said of the infection rates in New York, where more people have tested positive for COVID-19 than any other state. “We went from the highest cases, the highest viral transmission rate, to some of the lowest rates in the country. We now have to make sure that the rate continues to drop."

Cuomo said enforcement would be up to each of the three states, and violators in New York could face fines between $2,000 to $10,000.

Florida still has a similar rule on the books for travelers to the Sunshine State from those areas, but it was never widely enforced.

Meanwhile, Americans as a whole could be barred from traveling to as many as 27 European countries over fears they could spread coronavirus and bring a resurgence of COVID-19 cases to areas where the outbreak has slowed.

The European Commission is in the process of making recommendations to EU member countries on what restrictions should be put into place when their borders reopen on July 1. The EU encompasses most major European countries and many popular tourist destinations, including France, Italy, Spain and Germany.

The commission is compiling a list of which travelers should be allowed in, based on the status of coronavirus cases and spread in their countries of origin. The U.S., Russia and Brazil - the top three countries in the world in terms of infections - will likely not be on the list, according to a report by the New York Times.

The commission's recommendations aren't binding.

The EU's borders have been closed since mid-March. The U.S. also still has restrictions on travelers from most European countries.

With 2.3 million known cases of COVID-19 and more than 121,000 deaths, the U.S. is by far the hardest hit country in the world, according to data tracked by Johns Hopkins University. By contrast, the largest outbreak in the EU so far is in Spain, where about 246,000 cases have been reported and 28,325 people have died.

More than 9.2 million people worldwide are known to have been infected with COVID-19, and at least 478,160 have died,
