One thing that maybe someone could set me straight on . They talked about a serology test. This is pasted from the article. " She said serology tests would also have to be purchased for the airport and port to test its employees, for taxi drivers and those entering the country so within a day they will be free to roam. " So my question is about the cruse people . They are only there for one day . But the article said with in a day they could roam ?? How can that happen with them ? Please help with any clarification. Thanks
