There
are several ways disease-causing agents get from one person to another:
- Airborne
or droplet infection (e.g. colds, flu).
- Animal
borne or insect borne infection (e.g. rabies, malaria, Lyme Disease).
- Blood
borne infection (e.g. HIV, hepatitis).
- Food
borne or water borne infection (e.g. salmonella, giardia).
- Sexually
transmitted (e.g. chlamydia, gonorrhea, syphilis).
- Other
direct contact (e.g. some kinds of warts, scabies).
- Indirect
contact (e.g. colds and flu carried from person to person on dirty tissues,
money, door knobs, phones, computer keyboards).
