At which stage of life would one most likely suffer from immune senescence?
A. Adulthood
B. Geriatric
C. Adolescence
D. Prenatal
E. Neonatal
Correct option is B. Geriatric.
As age advances, the immune system will decline or senescent with major impact on health and survival. This puts the older adults to a higher risk of acute viral and bacterial infections. Newborn too are relatively susceptible to those infections, but immune system is not senescent.
Prenatal period is the period of growth within womb. The neonatal period is the period from birth to 1 month. Adolescent period is the transitional phase of growth and development between childhood and adulthood. Age between 10 and 19.
Adulthood is the period in which full physical maturity have been attained. It is the age starting from 20 or 21. Geriatric age refers to period of medical care for older adults. An age age around and above 65, where immune senescence can be observed.
