Vectors-These are diseases transmission which involves the piercing of the skin-vectors penetration e.g by mosquito. ticks.
Air borne which involves entry through the nasal passages, mouth, eyes to reach the body the respiratory tracts and the blood.
Blood borne diseases are transmitted from e.g piercing of the skin by contaminated objects needles, broken glass. If there is an opening in the skin these transmission is also possible.
Sexual can be transmitted through open sores at the genitals.or use of contaminated needle by infected subject. Sores in the mouth during kissing may be another route
food borne or water borne needs to enter through natural opening of the mouth to reach the body fluids and the blood through the GIT.
