Although fecal–oral transmission is usually discussed as a route of transmission, it is actually a specification of the entry and exit portals of the pathogen, and can operate across several of the other routes of transmission. [1] Fecal–oral transmission is primarily considered as an indirect contact route through contaminated food or water.
The infection can occur when a person puts anything into their mouth that has touched the feces of a person who is infected with E. histolytica, swallows something, such as water or food, that is contaminated with E. histolytica, or swallows E. histolytica cysts (eggs) picked up from contaminated surfaces or fingers.

The infection of a disease begins when a pathogenic (disease-causing) infectious agent, or a pathogen, is successfully transmitted from one host to another. [3] Pathogens leave the body of one host through a portal of exit , are carried by some mode of transmission and after coming into contact (exposure) with a new susceptible host, they enter ...
The first signs of dracunculiasis occur around a year after infection, as the full-grown female worm prepares to leave the infected person's body. [2] As the worm migrates to its exit site – typically the lower leg – some people have allergic reactions, including hives, fever, dizziness, nausea, vomiting, and diarrhea. [6]
There is a general chain of events that applies to infections, sometimes called the chain of infection [14] or transmission chain. The chain of events involves several steps – which include the infectious agent, reservoir, entering a susceptible host, exit and transmission to new hosts.
Transmissibility is the probability of an infection, given a contact between an infected host and a noninfected host. [8] Community transmission means that the source of infection for the spread of an illness is unknown or a link in terms of contacts between patients and other people is missing. It refers to the difficulty in grasping the ...
The U.S. is the only member state to have made such an exit strategy, Jašarević, of WHO, said. The former Soviet Union withdrew from WHO in 1949 during Cold War tensions, though returned years ...
Uropathogenic E. coli (UPEC) is responsible for approximately 90% of urinary tract infections (UTI) seen in individuals with ordinary anatomy. [11] In ascending infections, fecal bacteria colonize the urethra and spread up the urinary tract to the bladder as well as to the kidneys (causing pyelonephritis), [37] or the prostate in males. Because ...
