Question
Chapter 21, Problem 11SA
Summary Introduction
To answer:
The reason so as to why Epstein-Barr virus shows no ill-effects when this virus infects at age one even when medical care is poor and shows severe reactions when individuals are infected after puberty even when medical care is good in industrialized areas.
Concept introduction:
Epstein-Barr virus (EBV) is also known as Human herpesvirus 4 (HHV-4). This virus is responsible for causing contagious mononucleosis. It is an enveloped virus with icosahedral capsid having double-stranded DNA (deoxyribonucleic acid) replicates inside the nucleus of host cells. It suppresses apoptosis of B-lymphocytes, which may also lead to cancer.

small particle aerosols to large droplets. N95 respirators are tight-fitting
respirators that filter out at least 95% of particles in the air, including large
and small particles." (https://www.cdc.gov/coronavirus/2019-
