The sixth cholera pandemic (1899–1923) was a major outbreak of cholera beginning in India, where it killed more than 800,000 people, and spreading to the Middle East, North Africa, Eastern Europe and Russia.

The last cholera outbreak in the United States was in 1910–1911 when the steamship Moltke brought infected people to New York City from Naples. Vigilant health authorities isolated the infected on Swinburne Island, built in the nineteenth century as a quarantine facility. Eleven people died, including a health care worker at the island hospital.

At the turn of the century, the sixth pandemic killed more than 800,000 in India before moving into the Middle East, northern Africa, Russia and parts of Europe. By 1923, cholera had receded from most of the world, although many cases were still present in India.
^The Boston Medical and Surgical Journal. Massachusetts Medical Society. 1911. In New York, up to July 22, there were eleven deaths from cholera, one of the victims being an employee at the hospital on Swinburne Island, who had been discharged. The tenth was a lad, seventeen years of age, who had been a steerage passenger on the steamship, Moltke. The plan has been adopted of taking cultures from the intestinal tracts of all persons held under observation at Quarantine, and in this way it was discovered that five of the 500 passengers of the Moltke and Perugia, although in excellent health at the time, were harboring cholera microbes.
