An Icelandic news organization is reporting that three Icelanders who have tested positive for COVID-19 were infected with the respiratory disease in Denver.

The Iceland Monitor, the English-language arm of mbl.is, published a story on Friday attributing that information to Víðir Reynisson, chief superintendent of the county’s department of civil protection and emergency management.

So far, 117 Icelanders are confirmed to have contracted COVID-19, according to the news agency, with most of those people coming into contact with the novel coronavirus while visits the Alps in Italy, Austria and Switzerland. Almost 1,000 people are in quarantine.

It’s not clear when the three infected people were in Denver, where they may have stayed or when they traveled back to Iceland.

An email seeking comment on the report sent to Iceland’s Directorate of Health after the close of business hours in the county was not immediately returned on Friday afternoon.

Thirteen Denver residents had tested positive for COVID-19 as of Friday afternoon, according to the Colorado Department of Public Health and Environment, the second-highest concentration of cases in the state behind Eagle County.

President Donald Trump has banned foreign nationals from traveling to the U.S. from Iceland and most other European countries for 30 days starting at midnight Friday.

Icelandair has previously announced plans to continue flights to New York City, Chicago, Seattle and Washington, D.C., during the travel ban. The airline does offer nonstop flights between Denver International Airport and the Icelandic capital Reykjavik. The last flight from DIA to Reykjavik is scheduled to leave at 4:30 p.m. Saturday before Icelandair suspends service, according to airport spokeswoman Emily Williams.
