Explanation:
Attack rate of any pathogen describes the speed or morbidity by which the new or emerging population is at risk by the attack of the pathogen.
The attack rate can be calculated by the formula:
Attack rate = people affected or at the risk of infection / Total population.
65 people are affected and 72 people also shows the symptoms.
Attack rate = 65 + 72 / 485
Attack rate = 137 / 485
Attack rate = 0.28.
The attack rate percent = 0.28 × 100 = 28%.
Hence, the answer is 28%.
