Infectious Diarrhea Causes, Prevention, and Treatment [Infographic]

Infectious diarrhea, often called gastroenteritis, is an inflammation involving both the stomach and the small intestine. Occasionally, it has a non-infectious cause but results more often from food and water contamination. Thereby, it’s more prevalent in places with low water quality and poor food hygiene. Usually, infectious diarrhea is acute, self-limited, and does not require medications.

Common symptoms of Gastroenteritis

  • Diarrhea.
  • Nausea.
  • Stomach pain.

Other symptoms

  • Headache.
  • Fever.

Transmission of pathogens

Most gastrointestinal pathogens are transmitted by the fecal-oral contact, contaminated surfaces, hands, water or food. Infected people pass the pathogen from their bodies to the environment through stool while they’re sick.

Lack of hygiene in closed places can increase the spread of infection. Hence, the infection could be common in schools. Children can spread the infection to family members due to the close contact.

Types of infectious diarrhea

Causes of Infectious Diarrhea

Viruses are the main cause in children, but not for adults because of the acquired immunity. Instead, Campylobacter bacteria are the major cause in adults.

• Bacterial

The top 4 species are E.coli, campylobacter, salmonella, and shigella. Salmonella causes also typhoid fever, whereas, shigella is one cause of dysentery.

• Parasitic

Commonly, it’s either Giardia lamblia or Entamoeba histolytica, but mostly giardia. There is mucus with the green-colored stools and no fever.

Viral

Perhaps, a viral infection in GIT is why the folks call it stomach flu or intestinal flu. Rotavirus has been reported to be the viral cause in children. While norovirus is the leading cause in adults. Besides, a secondary infection may shoot the body temperature above 38.5°C.

There is no particular medication for the treatment of viral diarrhea. The only purpose, in this case, is to rehydrate the body so as dehydration can lead to serious problems. Severe dehydration may require hospitalization for treatment with intravenous fluids.

Treatment of Infectious Diarrhea

  • Do not overuse antibiotics, especially for a long period.
  • Anise, clove, cinnamon, and peppermint percolated drinks are effective for bloating and gasses.
