With new coronavirus (COVID-19) clusters sprouting aboard ships overseas, the U.S. cruise industry is extending its suspension of operations through October. The Hurtigruten cruise line was one of the first to resume sailing in June, offering cruises from Germany to Norway. Positive coronavirus tests have also been reported this week on cruise ships in Italy and Tahiti. The risk of infection aboard a cruise ship is elevated because of the close quarters. States that rely on the cruise industry, like Florida, Texas and Alaska, have been hit particularly hard.
