In case it has not been brought up yet, the Centers for Disease Control and Prevention (CDC) has excellent information on Cholera:

Also, as sad as it is a coincidence, 1854 saw not only the emigration of Wends to Texas but also the first time the dreaded cholera was accurately
located through a contaminated water source in the Broad Street public water pump thanks to the efforts of Dr. John Snow.
