Objectives

• Gain an understanding of the cholera bacterium and how it spreads as well as efforts to stop the spread.

• Describe low tech solutions to preventing outbreaks.

• Define epidemiology and terms associated with it.

From Aug 2008 to Jan 2009 there were over 40,000 confirmed cases of cholera in Zimbabwe. Over 2,000 of those were fatal.

Spread of Cholera

• Carried in water by small animals called copepods and in their egg sacks.

• Burst from the egg sacks when the copepod hatches and feed on the egg shell.

Now for a positive note…

• Epidemiology – the study of how diseases spread.– Ex: Rita Colwell studied the spread of the

pathogen cholera.

• Vaccines – used to increase resistance to infection by a disease by injecting genetic information from a dead or weakened pathogen into a host (that’s you).

Genetics and Treating Diseases

• Genetics – the science of heredity– Gives insights into how a disease can be

prevented, cured, or fought based on its genome.

• Genome – the complete set of genetic information for an organism.
