Chapter 14 Flashcards
5 stages occurring when a pathogen enters a host
- Incubation Stage
- Prodromal Stage
- Acute Stage
- Decline Stage
- Recovery Stage
Acute Stage:
disease reaches its greatest development
Transmission to others at it highest
Bloodborne Pathogens
Hepatitis B Virus (HBV)
Hepatitis C Virus (HCV)
Human Immunodeficiency (HIV)
Decline Stage:
First signs of recovery appear, signaling the infection is ending
Can experience a relapse if they overextend themselves
Hepatitis B management
Receive Hep B immunization
Hepatitis B Prevention
good personal hygiene, avoiding high risk activities
Can survive for attest one week in dried blood or on contaminated surfaces
Hepatitis B Signs and Symptoms
Flu-like symptoms -> fatigue, weakness, nausea, abdominal pain, headache, fever, dark urine, possibly jaundice
Possible to have no signs or symptoms
85% affected recover within 6-8 weeks
Hepatitis C Management
no vaccine
Eval for liver disease
Hepatitis C Prevention
Don’t share needles, razors. Syringes, toothbrushes, tattoo needles, piercing needles
Hepatitis C Signs and Symptoms
Jaundice, mild abdominal pain in upper right quadrant, loss of appetite, nausea, fatigue, muscle or joint pain, dark urine
80% infected have no signs or symptoms
HIV signs and symptoms: acute phase
fatigue, weight loss muscle or joint pain, painful or swollen glands, night sweats, fever
HIV signs and symptoms: after acute phase
HIV infected enter an asymptomatic phase and may go 8-10 years before developing signs and symptoms
Incubation Stage:
Time pathogen enters body until it multiplies to the point where signs an symptoms appear
Can last from a few hours to years
Prodromal Stage:
Variety of signs and symptoms may briefly develop
Pathogenic agent continues to multiply and host is capable of transferring pathogens to a new host
Should be isolated to prevent transmission to others
Recovery Stage:
Characterized by apparent recovery from pathogen
Susceptible to other pathogens
Body has built up immunity
