Task 1 - Cholera
i, You are interested to show the board of the charity some graphic
evidence about how easily one of your diseases can spread.
Carry out the experiment to investigate the oral fecal rout of disease
transmission and write this up. Photos of the result make a useful
evidence. In your conclusion/discussion describe what the experiment
shows about how cholera spreads.
Cholera is an infection of the small intestine by some strains of the
bacterium Vibrio cholerae.
A person can become infected by drinking water or eating food
contaminated by the bacterium. Common sources of foodborne
infection include raw or poorly cooked seafood, raw fruit and
vegetables, and other foods contaminated during preparation or
storage.
Bacteria present in the faeces of an infected person are the main source of contamination. The
bacterium can also live in the environment in brackish rivers and coastal waters. The disease can thus
spread rapidly in areas where sewage and drinking water supplies are inadequately treated.
