Concept explainers

Viral Infections

Viruses are abundantly found, minute entities that have genetic material enclosed within a protein coat. The proteinaceous material enclosing the genetic material of the virus is called a capsid. The genetic material could be either DNA (deoxyribonucleic acid) or RNA (ribonucleic acid). A virus is too minute to be looked at with naked eyes and therefore visualized with the help of a microscope. They are acellular entities that require a host for processes, such as replication, transcription, translation and multiplication. Plants, animals, and bacteria act as host wherein the virus reproduce. Viruses cannot multiply outside the host's body and thus are considered nonliving outside the host body.

Question

a. What specific host defenses do immunodeficient, cancer, and
AIDS patients lack that make them so susceptible to the viral
diseases in this chapter?
b. Given the ubiquity of most of these viruses, what can health care
workers do to prevent transmission of infection to other patients
and themselves?
