1)Illness

2)Infection

1)General subjective term "not feeling well"

2)Body invated by *pathogen either apprent or innapropriate

*something that causes disease

1)Disease

2)Syndrome

1)Conditions that impair normal tissue functions

2)Colelction of signs and symptoms

Sign

Symptom

Syndrome

Explain: Symptom

• non- contagious
• non-communicable
• chronic
• degenerative

1)Addictions

2)Cogenital anomalies

1) Alcohol

2)Fetal Alc. Syndrome/ Heart Defect

1)Allergies 

2)Introgenic

1)Asthma 

2)Caused by treatment: Infection

Those conditions that must be present or absent for the disease to occur

-present = virus 

AKA= Pathogen

-absent= lack of vit D

Infectious Disease Agents

Define- Communicable

(Name 3)

Define- Non-Communicable

(Name 3)

Communicable- Infectious or contagious

1) measles

2)HIV

3)gonorrhea

Non-Communicable- Non-infectious/non-contagious

1)cancer

2)diabetes

3)heart diseases

• enter hosts body
• ADHERE to specific host cells, then
• INVADE and COLONIZE host tissues, then
• INFLICT and DAMAGE- disrupt cells by releasing toxins

1)True Pathogens

2) Opportunistic Pathogen

1)influenza, virus, plague, shigella

2) HPV/ Staph/ Ecoli

Infectious Disease Agents 

1) Bacteria 2) Viruses 3) Fungi 4) Protozoa 5) Helminths 6) Prions

Give ex of each

1)Lyme disease 2) Flu 3)Ath. Foot 4)Malaria 5) roundworm 6) mad cow disease

What are Helminths?

3 Helminths infections?

Worms that enter boyd through open wound into intestines

1) roundworm

2)pinworm

3)tapeworm

1) What is a prion?

2)What disease is cattle associated with?

3)How was the disease transmitted?

1) Protein found in animal brains

2)mad cow disease

3)consuming animal beef

3 characteristics of infectious disease agents (9 total) DEFINE EACH:

1)Immungenicity

2)Infectivity

3)Pathogenicity

1) ability to provoke an imune system

2)ability to establish an infection (e.coli)

3)ability to produce clinical disease (gohnorrea)

4)ability to produce severe disease or death (flu)

5)hot,warm,dark,damp

6)single and multiple hosts

7)reactivation of latent or dormant infection- reoccurance

8) to be dormant / to survive for a long period 

- how long it lasts?

9)random evolution changes- viruses can change

Drift- minor change in antigenetic structure (reason flu vaccines somehwhat work)

Shift- major change in antigenetic structure (reason flu vaccines don't work)

1)Direct Transmission

2)Indirect Transmission

1)Kisses and sneezes

2)

• Airborne 
• Vehicle/ Vector borne
• Small particles in air (flea or fly)

1)Vector

2)Carrier

3)Reservior

1) animal that carries the disease without having it

2)person/animal with disease, potential source or infection

3)place disease enters

1)Active nature

2)Artificial active

3)Passive natural 

4) Passive artificial 

1. stage of susceptibility
2. stage of subclinical disease
3. stage of clinical disease
4. stage of recovery, disability, or death

1. pathogenic
2. reservoir
3. means of escape
4. mode of transmission
5. means of entry
6. host susceptibility

1. immunization
2. isolation treatment
3. blocking transmission

Are not communicated from person to person and are not ude to disease-causing organisms. 

Chemical- bee sting, poison ivy

Physical-heat, radiation

Psychological-noise, addictions

Social

Genetic

an evvironmental or behavior factor that is associated with increasing the risk of a particular illness or of a cause of death.

is one that has been established beyond reasonable doubt as a causal agent of an illness.
