• 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).
