The Port of New Orleans is testing embarking cruise ship passengers but not disembarking (!) ones. This when we have community spread in the parish already and have gone from 1 to 6 to 11 cases this week alone.
Although it is technically correct, this is the least contagious way. AFAIK most sick people were near sick persons for a considerable amount of time.

It seems false positives are a real thing [1] but can we afford even one asymptomatic infected individual that might be a super spreader? In shifting away from containment are we just accepting these?
> Although the possibility of transmission from an asymptomatic person has been reported （https://www.nejm.org/doi/full/10.1056/NEJMc2001468）, little is known on how Coronavirus disease 2019 (COVID-19) spreads from person to person. Generally speaking, with most respiratory viruses, people are thought to be most contagious when they are most symptomatic. https://www.cdc.gov/coronavirus/2019-ncov/about/transmission...
That CDC link [2] states that:
> People are thought to be most contagious when they are most symptomatic (the sickest). Some spread might be possible before people show symptoms; there have been reports of this occurring with this new coronavirus, but this is not thought to be the main way the virus spreads.
