The process of transmission may be simple or involve multiple steps.
This demonstrates how water can get polluted with pathogens.
This publication explained transmission routes and barriers to the transmission of diseases from the focal point of human feces.
Modifications have been made over the course of history to derive modern-looking F-diagrams.
These diagrams are used in many sanitation publications.
The "F-diagram" (feces, fingers, flies, fields, fluids, food), showing pathways of fecal–oral disease transmission.
Based on evaluation studies included in the current review, only three primary prevention strategies have demonstrated significant effects on sexually violent behavior in a rigorous outcome evaluation: (VAWA; Boba & Lilley, 2009).
The number of alerts in each category determines the order in which they appear in the Outbreaks Near Me section.
The category with the greatest number of alerts appears first.
The common fecal-oral routes are fingers, flies, fields, fluids, and food.
Analingus, the sexual practice of licking or inserting the tongue into the anus of a partner, is another route.
