Quarantine law began in Colonial America in 1663, when in an attempt to curb an outbreak of smallpox, the city of New York established a quarantine. In the 1730s, the city built a quarantine station on the Bedloe's Island. The Philadelphia Lazaretto was the first quarantine hospital in the United States, built in 1799, in Tinicum Township, Delaware County, Pennsylvania. There are similar national landmarks such as the Columbia River Quarantine Station, Swinburne Island and Angel Island. The Pest House in Concord, Massachusetts was used as early as 1752 to quarantine those suffering from cholera, tuberculosis and smallpox.
