Answer:

28.2%.

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%.

Electroconvulsive Therapy (ECT) is done under anesthesia in which currents which are small in magnitude are passed on through the human brain in patients with severe depression.

ECT is used when the patient does not respond to other treatments which involves Electrically stimulating the brain while patient lies in anesthesia.
