In a family of 6, one person is the primary case of measles and one other member is already immune. Two further members develop measles within the incubation period. The secondary attack rate is:
सही उत्तर: ग) 50%
Susceptible contacts = 6 − 1 (primary case) − 1 (immune) = 4; SAR = 2/4 = 50%. Using 6 or 5 as denominator is wrong because the primary case and immune persons are excluded.

If the basic reproduction number (R0) of an infection is 4, the minimum proportion of the population that must be immune to interrupt transmission (herd immunity threshold) is:
सही उत्तर: ख) 75%
Herd immunity threshold = 1 − 1/R0 = 1 − 1/4 = 0.75, i.e. 75%. 25% is simply 1/R0, a common slip.
