Secondary attack rate refers to the spread of disease in a family, household, dwelling unit, dormitory, or similar circumscribed group. The spread of infection from an index case (the initial case, i.e. the case that introduced the organism into the population) to the attending medical staff is called secondary attack rate. It is a good measure of person-to-person spread of disease after the disease has been introduced into a population.
