1.

Biological Transmission – Propagative

a)

Agent multiplies. Example: Plague (Flea)

b)

Agent does not multiply. Example: Malaria (Mosquito)

c)

Agent is transmitted through direct contact. Example: HIV

d)

Agent is transmitted through contaminated water. Example: Cholera

2.

Prevention of Communicable Diseases

a)

Primordial: Improved sanitation, Housing, Education

b)

Primary: Immunization, Vector control, Safe water

c)

Secondary: Screening, Early treatment, Isolation

d)

Tertiary: Disability limitation, Rehabilitation

3.

Biological Vector

a)

Agent that transmits disease without multiplying, e.g., Housefly → Typhoid

b)

Agent multiplies/develops, e.g., Mosquito → Malaria

c)

Agent that only carries the disease, e.g., Tick → Lyme Disease

d)

Agent that cures diseases, e.g., Antibiotics → Bacterial Infections
