Question | Answer |
Asepsis | Absence of pathogens |
Communicable | Disease capable of being transmitted more or less rapidly to other persons; also called contagious |
Universal Precautions | Guidelines recommended by the Center for Disease Control to prevent the transmission of blood-borne pathogens |
Sterile | 0 pathogens/microorganisms |
Vector | An animal, especially an insect, that transmits pathogens from infected to non infected persons
Can carry pathogens on their body or inside their body, they are indirect |
Terminal sterilization | Process of sterilizing articles after they have been used and before putting them into circulation |

Occurrence of infection | *Portal of entry
*Resistance of host
*Number of organisms
*Virulence of the organism |
Types of infections | *Primary
*Secondary
*Mixed
*Latent |
Secondary | Usually caused by opportunistic type |
Mixed | Appendicitis, trench mouth, wound infection |
Latent | Early TB, malaria |
Acute | Runs a rapid and severe course terminating abruptly |
Chronic | Runs a slow course over a long period of time; may last for weeks to years |
Acute | Period of actual illness with symptoms, degree of fever, and length of time depending upon the disease, condition of patient and treatment |
Convalescent | Begins with decline of fever and acute symptoms; length of time depends upon the severity of the acute stage, treatment, and general health of the patient |
Incubation | Period between entrance of organisms to the body and onset of symptoms |
Prodromal | Short period, usually a day or less, when symptoms are vague or cause only mild discomfort |
What is the order of stages of an acute infection? | *Incubation
*Prodromal
*Acute
*Convalescent |
