Unclean water can contain harmful bacteria, viruses, and parasites that can cause diseases like cholera, typhoid, and dysentery. When people consume or come into contact with contaminated water, they are at risk of getting sick, leading to the spread of diseases within a community.
Legionnaire's disease is caused by inhaling small droplets of water contaminated with Legionella bacteria. These bacteria thrive in warm water environments like air conditioning systems, hot tubs, and plumbing systems. The disease is not spread from person to person.
A vehicle-borne disease is an infectious disease that is transmitted through a contaminated object or substance, such as food, water, or insects, rather than through direct person-to-person contact. This type of disease can spread quickly through a population if the contaminated vehicle is not identified and controlled.
The packed them on ships and had them at seas for days with limted water and food. and some would die at sea and since they were all packed in tight on the ship disease spread. And it slowed down the trade bc they would care disease with them and spread among there new home.
Disease spread rapidly in slave ships due to overcrowded and unsanitary conditions. Poor ventilation, lack of clean water, and limited access to medical care contributed to the rapid transmission of infectious diseases among slaves who were already weakened by malnutrition and physical abuse.
A faulty sewer line can leak sewage into the surrounding soil and groundwater, contaminating sources of drinking water. This contaminated water can spread disease-causing bacteria and pathogens, increasing the risk of waterborne diseases such as cholera, dysentery, and hepatitis among people who consume or come into contact with the polluted water. Regular maintenance and prompt repair of sewer lines are essential to prevent the spread of waterborne illnesses.
In the middle ages city dwellers were crowded together and usually had unclean water supplies. They had no knowledge of the causes of disease so could not do things to prevent diseases spreading, such as collecting waste and keeping it away from their water supply.

Cholera is a disease that is spread by contaminated water, particulary, by water that is contaminated by human sewage. If water is properly treated, it will not spread cholera and the disease will be prevented.
The disease is spread through water.
Its called diarrhea
fecal-oral
The spread of disease
There could be spills on the land, infected water, radiation.One way that land use change may contribute to the spread of infectious diseases is when these changes affect the local insect population. For example, mosquitoes spread malaria. If mosquitoes are drawn to an area in large numbers by use change, the spread of malaria is a risk.
Disease, poisonous animals, unclean water, lack of food. It depends on what part of Africa though.
Traveler's diarrhea disease is usually spread by contaminated food or water.
the plage was spread throughout animals, which carried fleas, and fleas carried the disease. china did not carry the disease, because they had boiling water.
Since disease can come from humans to animals, and vise versa, animals can be in water and infect it with its problems.
