What is Cholera

According to the World Health Organisation, there are roughly 3‚5 million cholera cases and 100,000‚ 120,000 deaths worldwide due to cholera every year. A cholera vaccine provides protection from the infection and is 85% effective. The vaccination is particularly important for people traveling to remote regions as well as aid workers and medical professionals working in cholera areas.

Cholera is caused by an infection with vibrio cholerae bacteria. Although improvements to the sanitation system and an improved knowledge of personal hygiene have eradicated cholera in large parts of Europe, the illness is still present in many countries. Cholera bacteria spread through contaminated food and water, as well as contact with faeces. Cholera is not commonly passed directly from one person to another.

The illness often remains symptomless but it can cause symptoms affecting the digestive tract, such as diarrhoea, nausea, and vomiting. Some patients also complain about stomach cramps. When left untreated, cholera can lead to complications such as dehydration and a lack of electrolytes, especially in a hot climate. In severe cases, dehydration can be fatal. A cholera vaccine is available for travelers who may be at risk.
