What does "quarantine" mean?
Quarantine is defined as ‘strict isolation designed to prevent the spread of disease’. Quarantine stations were created when necessary in Europe’s ports so that vessels suspected of carrying infectious diseases could be isolated for the duration of the quarantine. The origins of the word quarantine come from the Italian quaranta (i.e. quaranta giorni) which is forty and relates to initial period of quarantine of 40 days during the fourteenth century. At North Head the period of quarantine varied depending on the incubation time of the disease.
