The specific host defenses that immunodeficient, cancer, and AIDS patients lack that make them so susceptible to the viral diseases in this chapter. 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.

Students have asked these similar questions

a. During which stages of an infectious disease does the host exhibit signs and symptoms? Is there a correlation between this and when a disease is communicable? b. Why are some viral diseases, like smallpox and polio, no longer seen in the United States? Why are many bacterial disease, like syphilis, no longer a death sentence? Think about how these two types of microbes infect humans. Why might we make an effort to treat viral diseases before infection but continue to treat bacterial diseases after infection? c. Based on the graph below, which pathogen is more virulent: Agent 1 or Agent 2? Explain. 100 Agent 1 LD5 = 400, Agent 2 LD50 = 600 25 100 200 300 400 500 600 700 800 900 1,000 Dose (organisms administered per animal) Percent mortality 75

Please match the definition. 1. Layers that surround the virus, giving it an exact shape that will interlock with the host cell. 2. Process where a virus inserts its DNA into and replicates with the host cell's genetic material (does not destroy cell). 3. Non-living particles that reproduce inside a living cell. 4. The genetic material (DNA or RNA) inside a virus. 5. Process by which a virus enters a host cell, uses its raw materials and energy to create new viruses, which then burst from the host cell (destroying it) and spread. The answer choices are is on the picture.

Which link in the chain of infection is the intervention described below meant to break? "N95 respirators reduce the wearer's exposure to airborne particles, from 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."
