Boats full of fleas and lice
Sailors and pirates lived in crowds on ships. Because of this and the lack of hygiene, diseases were spread transmitted by insects, fleas and lices.
At that time ignorance was in the ships and on land to port and starboard
They transmitted diseases between Sailors and Pirates
Fleas: Something very common at the time. The Louse was very widespread among the population of ships and even on land
The lack of hygiene of the time and the poor living conditions on the boats favored their presence
Crammed into the boats
The lack of space on ships, where sailors and pirates lived crowded together, made it easier for lice to spread among them.
They did not change their clothes, nor did they clean
It was usual that for convenience and the difficulty of cleaning it in the sea, people did not change their clothes.
Worse than their discomfort were the diseases they transmitted
Little annoyance leads to disease
Transmitter of disease in large groups of people
At that time it was not considered medically important, it was only considered a nuisance. They were not known to transmit diseases rapidly.
As long as a case appeared on the ship, lice and fleas quickly spread the disease among sailors and pirates.
Salt water cleaning
In places where there were rules and it forced to wash clothes, as in large warships, it was done wrong. Cleaning with fresh water was prohibited because it was very scarce. Cleaning with sea water was incomplete and caused later discomfort.
