Epidemiology The study of diseases and populations at
risk. Investigates the sources of disease,
routes of transmission, and infection
patterns in an effort to maintain good
public health.
Epidemic When a disease shows a higher incidence
than expected
Pandemic When a disease has spread across very
large regions, even continents.
What kinds of factors beyond Natural environment of a region, the
the health of an individual can genetic background of a population,
contribute to the spread of a infrastructure present in a nation, and
disease? cultural and social practices.
, Cholera Spreads via fecal-to-oral route, so in a
country like the U.S., where we have
extensive sewage systems and water
treatment plants, it's not an issue. But in
places with less water infrastructure, it is a
huge problem.
HIV Infects human T-cells by binding to a
protein called CCR5, which enables it to
enter the cell, begin propagating, and
cause immune cell death. This results in
immunodeficiency.
A small percent of Europeans has been
found to be naturally immune to HIV
because their CCR5 genes are mutated.
Maybe this should be a
therapeutic/preventative target.
