What are 'Enteric Diseases'?

Enteric diseases are illnesses caused by pathogens that infect the intestines (the enteric tract). These diseases typically spread through contaminated food, water, or hands, and are closely associated with poor sanitation and hygiene.

They are caused by bacteria, viruses, parasites, or sometimes toxins. Common pathogens include:

Type    Examples
Bacteria    Salmonella, Shigella, E. coli, Vibrio cholerae
Viruses    Rotavirus, Norovirus, Hepatitis A
Parasites    Giardia, Entamoeba histolytica, Cryptosporidium

How do they spread?

  • Fecal-oral route

  • Contaminated drinking water

  • Poor food hygiene

  • Person-to-person contact

  • Contaminated surfaces or utensils

How can they be prevented?

  • Access to clean water and sanitation

  • Handwashing with soap

  • Food safety and hygiene

  • Vaccination (e.g., for cholera, hepatitis A, rotavirus, typhoid)

  • Public health education

Typical vaccines for enteric diseases
