This first wave came from India in around 1817.
The second wave was far worse!!! Why?
Well. The first wave lingered around a while and partied and multiplied and grew more virulent. FACT (?)
By 1828 it had travelled to China via trades routes. From China it went to Japan, Afghanistan, and even over the Urals to Russia! No passport needed – hey?
By late 1831 it arrived in the UK. After having stowed away on a ship.
By early 1831, frequent reports of the spread of the pandemic in Russia prompted the British government to issue quarantine orders for ships sailing from Russia to British ports. By late summer, with the disease appearing more likely to spread to Britain………
The epidemic reached Great Britain in December 1831, appearing in Sunderland, where it was carried by passengers on a ship from the Baltic. It also appeared in Gateshead and Newcastle. In London, the disease claimed 6,536 victims; in Paris, 20,000 died (out of a population of 650,000), with about 100,000 deaths in all of France. In 1832, the epidemic reached Quebec, Ontario, and Nova Scotia, Canada; and Detroit and New York City in the United States. It reached the Pacific Coast of North America between 1832 and 1834. The pandemic prompted the passage of the landmark Public Health Act and the Nuisances Removal Act in 1848 in England.
In mid-1832, 57 Irish immigrants died who had been laying a stretch of railroad called Duffy’s Cut, 30 miles west of Philadelphia. They had all contracted cholera.
