Virus spread has implications for cruise ships, things to look at to help eliminate virus spreading on cruise ships

air filters for each cabin
water filters cold taps for each cabin

water basins and shower bases that are heated to help eliminate virus spread
Air filters in the U of the basin to prevent air flow back from the sewage system

toilets that suck in air and exhaust it
seat covers that are designed to come out and cover the toilet when flushed (containment of water vapour = containment of virus spread)

Air filters in the U of the toilets to prevent air flow back from the sewage system
water Filters for cold water in the toilet flush tank

Filters in al the water tanks

What about legionnaires disease?

(In hot water.)

Have facilities to isolate/quarantine anyone that comes down sick.

Get the well people off the ship as soon as you can.

Just caught sight of this thread.

The ships are not the problem.

Their design is no ‘worse’ than the designs of modern major hotels, perhaps better in some ways.

The problem is the people.

The ships carry a population of a couple of thousand people. That population is entirely changed, on average,every 10 to 14 days. Every 1.5 to 2 weeks, a whole new population, equivalent to a small town, leaves, and a new one arrives.

Those populations come from all over the place, and bring with them their own incipient illnesses, their germs, their attitudes, and their habits. They’re exposed to whatever bugs the previous rapidly-changing populations, as well their fellow-passengers in the current group, had/have brought along, and left behind.

The casualness about hand hygiene which some (a lot?) of them have (while not a problem in their home environments, where the germs are ‘familiar’ and the fairly stable population more or less all used to them) leads to them bringing or picking up and spreading about a vast acquired catalogue of germs, some of which many aboard may not have any had exposure to prior to the cruise.

No matter how diligent the ship’s company are in trying to keep things clean and hygienic, their efforts can be outstripped by the unknowing efforts of the population.

Warning, devil’s advocate mode.

Start by putting self-closing bulkheads so if Antone does get sick then they can be locked in with only about 20 other passengers.

Within each such compartment take fresh air directly in from outside and directly back outside, through the side of the ship way below any open deck, preferably below the water line, or incinerate outgoing air in the diesels.

Next, issue face masks to everybody.

As colds are airborne diseases, that’s all that’s needed.

ok version 2

1 Air filters for air conditioning in each cabin
2 The U of the basin, shower and toilet designed to not allow airflow back from the sewage system.
3 Toilets that suck in air and exhaust it (air vapours)
4 Seat covers that are designed to come out and cover the toilet when flushed (containment of water vapour = containment of virus spread)
5 Water basins and shower bases that are heated (after each use) to help kill germs.

What if a condition of the purchase of the ticket is to isolate for two weeks prior to any overseas travel?

Then each passenger gets checked for a virus by a doctor or nurse

Same for ships, air flights.

and all passengers wear masks all the time
