“What I just experienced? I never want to experience it here,” said Zurek, 63, a concrete business owner who traveled last month to China with his wife, Annie, 60, to visit her family and meet their new baby granddaughter. After learning of the virus and cutting their visit short to return home after 10 days, the Zureks decided to quarantine themselves in their Highland, Indiana, home for about two weeks even though they haven’t shown any signs of the virus, like fever and cough.
