Cholera: transmission routes, preventive measures

20.09.2024

Cholera is an acute intestinal infection that occurs as a result of human infection with cholera vibrios.

Routes of infection transmission:

  • Water: when drinking water, using ice, swimming in bodies of water, washing dishes; 
  • Food: when consuming foods that have not been sufficiently cooked; 
  • Contact-household: through unwashed hands and household items.

The source of infection is a person who has contracted cholera or is a carrier.

Often the infection causes diarrhea, nausea, vomiting, or has no obvious clinical manifestations. In some cases, 12 hours to 5 days after the bacteria enter the body, patients develop severe watery diarrhea and vomiting. In these cases, the loss of large amounts of fluid can quickly lead to severe dehydration, which can be fatal if not treated properly.

Preventive measures:

  1. Use boiled or bottled water for drinking and household purposes (for example, brushing teeth), washing fruits and vegetables, making ice for cooling drinks; 
  2. Avoid eating raw and undercooked foods (especially fish and seafood), and do not buy food from street vendors or random vendors; 
  3. Use only water bodies permitted for organized recreation for swimming. When swimming in open water bodies or swimming pools, avoid getting water in your mouth; 
  4. Observe personal hygiene rules (wash hands with soap, use antiseptic after visiting toilets, public places, before eating).

When going on a trip, it is necessary to familiarize yourself in advance with the epidemiological situation in the destination country and preventive measures.

According to the World Health Organization, there is a high activity of the cholera epidemic process in the world, including in Asian countries (India, Bangladesh, Thailand) and Africa (Somalia, Burundi, Zambia, Zimbabwe, Nigeria, Ethiopia, Kenya, Cameroon, Democratic Republic of the Congo, Mozambique).
