| 5 stages of infection in humans |
|
Definition
1. incubation- no sign or symptoms
2. prodromal- vague, general symptoms...SUBJECTIVE
3. illness- most severe, most infectous...OBJECTIVE
4. decline- decrease symptoms
5. convalescence- no symptoms |
|
|
Term
|
Definition
1. localized infection- contained
2. systemic infection- blood/lymph
3. acute disease-rapid, short (ebola)
4. subacute-in between acute and chronic
5. chronic- slow lengthy (HIV)
6. latent infection- mostly virus, hidden (herpes)
7.primary infection- virus
8. secondary infection-bacteria |
|
|
Term
|
Definition
1. entry- into body >> portal of entry
2. attachment- virus (attach and enter cell)
bacteria (attach)
attach to tissue by receptors called integrins
3. multiplication- localized or systemic (growth curve)
4. invasion or spread
5. evasion of host defenses
6. damage of host tissue- may cause death to host |
