Question

What does the F-diagram represent?
A) Fecal-oral disease transmission
B) Fecal disease transmission
C) Oral disease transmission
D) None of the above

Answer 1

Hint: The F-Diagram is one among the various tools within the Participatory Hygiene and Transformation (PHAST) methodology which seeks to vividly describe intimately the fecal oral transmission route. It's a cycle characterized by F's as follows: Fluids-the drinking of contaminated water. Fingers-faecal contamination of fingers/hands.

Complete answer:
Diseases caused by fecal-oral transmission include diarrhea, typhoid, cholera, polio and hepatitis.
Fecal-oral transmission means the germs that cause illness are found within the stool (feces) of an infected person, and are spread to a different person. This happens when an individual touches the stool of an infected person or an object contaminated with the stool of an infected person and ingests the germs.
The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and customary Vehicle. The portal of entry is the means by which the infectious microorganisms gain access into the new host. This will occur, for instance, through ingestion, breathing, or skin puncture.
There are two sorts of contact transmission: direct and indirect. Direct contact transmission occurs when there's physical contact between an infected person and a susceptible person. Indirect contact transmission occurs when there's no direct human-to-human contact.

Hence, option (A) is correct.

Note:
Modern vehicles are available in two different transmission types – automatic or manual. During a manual transmission, the driving force is liable for shifting the gears, while during a vehicle with an automatic drive, the car does the shifting for you.
