Are There Vaccines Available For Cholera?

What Is Cholera?

Cholera is an infectious disease that affects mostly the intestines, but causes complications to the rest of the body. Once a person suffers from cholera, the first parts of the body to be affected are the intestines. It is an infection caused by a bacteria known as the Vibrio cholerae bacteria. This bacteria invades the human body and starts multiplying.

The Vibrio cholerae bacteria has the ability to survive in different environments. As a result of this, the infection is very easily spread. This also makes cholera a highly contagious and dangerous infection. This means that the infection can be transmitted from one person to another through a number of mediums.

Cholera has been for long been a dangerous infection, causing several deaths all over the world every year. Over a long period of time, different agencies and organizations have been looking for the best treatment for the infection.

  • Drinking contaminated water: This is one of the most common causes of cholera. This water may be mostly contaminated though the feces of an infected person.
  • Coming into contact with feces of an infected person: Most of the Vibrio bacteria are accumulated in the infected person’s feces. As a result of coming into contact with the feces, one can easily get the infection.
  • Contaminated food: Intake of contaminated food may arise from buying vendor foods or poor management and storage of foods.
  • Poorly prepared food: Especially fish. The Vibrio cholerae is known to live within some sea creatures. Consuming these creatures without cooking them thoroughly can transmit the bacteria into your body.
