Chapter 24.L2, Problem 4CT

Summary Introduction

To analyze:

1. The specific host defenses that immunodeficient, cancer, and AIDS patients lack that make them so susceptible to the viral diseases in this chapter.
2. The precautions health care workers can take to prevent transmission of infection to other patients and themselves, given the ubiquity of most of these viruses.

Introduction:

The body’s immune system has mechanisms to protect it from viral pathogens. These mechanisms are weakened or lost in certain conditions, making such individuals vulnerable to viral diseases. Given that viruses are so widespread and may be quite contagious, healthcare workers must take special precautions for their own safety and that of their patients.
