1. It is when the host defense overcomes pathogen’s secondary infections.
2. It is when the individual experiences the typical signs and symptoms on the disease.
3. It is when the pathogens begin to invade tissues.
4. It is when the tissue damage is repaired and patient regains strength.
5. It is a silent stage time between infection and the appearance of signs and symptoms of the disease.
Answers
Answer:
1)
pathogens are able to get past the first line of defence, for example, through a cut in your skin, an infection develops. The second line of defence is a group of cells, tissues and organs that work together to protect the body. This is the immune system.
2)
A disease is any condition in which the normal structure or functions of the body are damaged or impaired. Physical injuries or disabilities are not classified as disease, but there can be several causes for disease, including infection by a pathogen, genetics (as in many cancers or deficiencies), noninfectious environmental causes, or inappropriate immune responses. Our focus in this chapter will be on infectious diseases, although when diagnosing infectious diseases, it is always important to consider possible noninfectious causes.
3)
Microorganisms capable of causing disease—pathogens—usually enter our bodies through the mouth, eyes, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread—or be transmitted—by several routes.
4)
The inevitable response to any implant is wound healing comprised of hemostasis, inflammation, repair, and remodeling. For nondegradable smooth-surfaced implants, repair and remodeling leads to isolation of the implant through tissue encapsulation. The nature of the encapsulation tissue and the cellular participants in the immune reaction leading to this outcome varies depending on the site of implantation and the type of tissue that hosts the implant (not to mention the skill of the surgeon).
5)
This stage of subclinical disease, extending from the time of exposure to onset of disease symptoms, is usually called the incubation period for infectious diseases, and the latency period for chronic diseases. During this stage, disease is said to be asymptomatic (no symptoms) or inapparent.
