Disease Detectives B/C

An epidemiologist studying an outbreak of E Coli finds out that the more hamburgers someone ate, the more the person was at risk for contracting E Coli. Why is this information important?

This would suggest that hamburgers caused the E. coli outbreak (dose-response relationship), but more inquiry would be required to conclude anything.

Describe the differences between an outbreak, epidemic, and pandemic.

Describe the differences between an outbreak, epidemic, and pandemic.

Outbreaks have more cases than expected in a particular place (size does not matter) and time. Epidemics have a large number of people affected over a large area (usually a couple of countries), while pandemics are larger, possibly multiple continents.

Give three reasons why it is important to establish an outbreak before conducting a study about a particular disease.

Give three reasons why it is important to establish an outbreak before conducting a study about a particular disease.

1) There may be no real threat from the disease, wasting resources.

2) If there is no outbreak, the mode of transmission may also be misinterpreted.

3) It is more difficult to conduct a study about a disease if there are few people suffering from it.
