The ship should have docked at a remote island, the passengers and crew let ashore and observed for three months. Much could have been learned about the nature of this disease.
FIRST! We need to bring back mfg of medicine/mask/equipment in case of true pandemic.
SECOND, we need to reactivate quarantine islands on US soil/territories. I nominate those islands closed down by Clinton/Bush/Obama to include Midway Island, Johnston Atoll, etc. We need to rebuild those. We also need to reactivate Pease AFB and Presque Isle AFB as back up CONUS quarantine. All of the above were former SAC bases. We need to spin up Hickman AFB, Andersen AFB (Guam) and Ramey AFB in Puerto Rico as primary quarantine bases. There are a couple of USVI air strips we can use for East Coast/Caribbean.
As far as the rest of the world? Lots of former SAC bases/greek islands, diego garcia, Thule, Canary Islands, etc.
BRING BACK quarantine islands!
