These enteric infectious diseases all have symptoms of abdominal pain and diarrhea, and some have symptoms of fever. They belong to inflammatory diarrhea, which is caused by the destruction and massive exudation of inflammation, ulcer and other pathological changes to the integrity of intestinal mucosa.
There are many ways to produce intestinal infectious diseases: caused by bacteria, viruses, parasites and other infections, pathogenic bacteria can enter the digestive tract through the mouth and reproduce in the intestinal tract.
In addition, intimate contact such as shaking hands and kissing, as well as the spread of insects such as cockroaches, are also one of the reasons for intestinal infectious diseases. Virus transmission is mainly caused by blood, sexual life or vertical transmission between mother and infant. Therefore, attention should be paid to personal hygiene, and typhoid fever, cholera, etc. should also be isolated in a timely manner.
