What is the definition of a vector?CaRoLyN_s wrote:We all have our moments.![]()
Correct!! Your turn!
A vector is an organism that transmits disease. Examples include mosquitoes (transmit malaria) , possibly dogs (transmit rabies) and ticks (transmit lime disease)

What are false positives and false negatives and why are they important when investigating an outbreak?
False Positives are where you say something is false even though it is true. False Negatives are where you say something is true even though it is false. False Positives occur when there is enough random variation in the population to assume that something has changed, on the other hand False Negatives occur when the change is too small to think much has changed.

Outbreak: occurrence of more cases of a health condition than usual in a given area. Epidemic: a widely dispersed, rapidly spreading occurrence of disease in an area. Pandemic: an epidemic on a global scale.
