fatigue, anorexia, N/V, enlarged lymph nodes, positive blood cultures.
What factors influence susceptibility to infections?
Inadequate hand hygiene, chronic diseases, surgical climates, lines-drains-tubes, breaks in skin,
impaired circulation, immunocompromised, medications that inhibit immune response, medical
procedures, age, smoking, drugs, IV drug use/shared needles, multiple sex partners, unprotected
sex, poor nutrition, stress, crowded environments, poor living conditions, visiting regions with
parasites and diseases and poor sanitation.
What are the five classifications of an infection?
1. Incubation
2. Prodromal
3. Illness
4. Decline
5. Convalescence
What is the first classification of infection?
Incubation- infection begins, pathogens multiply, person does not suspect that they have been
infected, but may be capable of infecting others. Can last one day with influenza or several months
to years with tuberculosis.
What is the second classification of infection?
Prodromal- first appearance of vague symptoms. Mild throat irritation
What is the third classification of infection?
Illness- patient becomes ill and shows signs and symptoms of disease.
What is the fourth classification of infection?
Decline- Signs and symptoms of the infection began to fade. When the immune defenses along with
medical therapies reduce the number of pathogenic microbes.
What is the fifth classification of infection?
Convalescence- healing begins as the remaining number of microorganisms approaches zero. Can be
as short as a day or long as a year.
What are the three types of infections?
1. Primary
2. Secondary
3. latent
, What is the primary type of infection?
First infection that occurs.
What is the secondary type of infection?
Occurs after infection can be caused by immunocompromise state.
What is the latent type of infection?
Can cause no symptoms for long periods/hides.
What is the chain of infection?
1. Infectious Agent
2. Reservoir
3. Portal of Exit
4. Mode of Transmission
5. Portal of Entry
6. Susceptible Host

2. Exercise
3. Good metal health
