How is cholera spread from one person to another?
If the infected person sneezes close to an un infected person Cholera is caused by a bacterium called Vibrio cholerae. A person gets cholera by drinking water or eating food infected with the bacterium. Once swallowed, it settles in the lining of the small bowel and releases a toxin (poison) that can cause the body to flush liquid into the small bowel, resulting in watery diarrhea. The bacterium that causes cholera is usually transmitted by water contaminated with human feces, but it can also be transmitted by ingesting contaminated food, especially raw or undercooked seafood and shellfish. Nost people infected with cholera have no symptoms, yet they carry the bacteria for few weeks, excreting them slowly into the water supply.
How did john snow help save lives?
Snow used epidemiological and statistical methods to identify the water pump in a district of London that was the source of cholera germs that had caused an outbreak of the disease.

Flood water can be contaminated with chemicals salt and unsafe levels of microorganisms Explain why this should be a concern to people in a community?
"Chemicals" becomes a hazard of acute poisoning, chronic carcinogenicity, or simply gastrointestinal distress. "Salt" becomes a problem with dehydration. The kidneys excrete fluid with a more-or-less constant salinity. If higher salinity is ingested, the body is drained of fluids to achieve the kidney's target. "Microorganisms" becomes a problem with disease. Cholera is a real issue in contaminated waters, as is e. coli. A community will suffer if its members are ill and cannot help one another.
