State health codes dictated the rules surrounding the conveyance of a person diagnosed with a quarantine-able disease like leprosy. Leprosy patients were denied the use of public transportation.

Only designated vehicles would be used to transport patients to the Louisiana Leper Home (1894-1920) which became the National Leprosarium (1921-1999).
