Transmission of cholera is typically through the fecal oral route. This was a problem because people didn’t have very good sanitation in poorer countries which allowed the disease to spread. The disease spread through the water because people went to the bathroom next to the water which infected the streams. The water was used as the main water supply for the villages. Then anyone infected with the disease could infect anyone that came in contact with anything their infected hands touched mostly food.

The reason this isn’t a problem in more developed countries is because of technology and knowledge about how infectious diseases are spread. One invention that prevents the spread of cholera is the toilet and sinks. This allows people to keep their fresh water away from their waste water. John Snow was one of the people who gave us the knowledge we have today about cholera. John Snow was able to trace cholera back to water and waste in London. This led to and overall change in this city as well as other cities and allowed for a change in public health overall. Whitehead worked with snow to prove that the Broad street pump was the source of the cholera infections. Robert Koch is the one who is credited as being the first one to identify the disease while Filippo Pacini was completely ignores when he tried to tell people of the disease. These guys completely changed the way we look at germs and sanitation as well as increase the amount of knowledge on infectious diseases.

In the fall of 2010 after the earthquakes, cholera began to spread in Haiti. The cholera spread from a United Nations Peacekeeping camp in Haiti. The disease was brought over from Nepal when Nepalese peace workers were staying at the United Nations camp and due to poor sanitation, the sewage went straight into the local waterways. They have quarantined patients with the disease and treated them for cholera. They have yet to put in a new national water and sanitation system or to pay for any damage they caused.
