OXFORD'S LEADING TRAVEL VACCINATION CLINIC
Cholera Vaccination Oxford
Cholera is a highly contagious bacterial infection caused by the bacterium Vibrio cholerae. It is primarily transmitted through contaminated food and water, and it can lead to severe diarrhoea and dehydration if left untreated. If your travel plans include destinations where cholera is prevalent, it is strongly advised to seek vaccination as a preventive measure.

Frequently Asked Questions
What is Cholera?
Cholera is a potentially life-threatening diarrheal disease caused by the bacterium Vibrio cholerae. It is mainly transmitted through the consumption of contaminated food and water, particularly in areas with inadequate sanitation and poor hygiene practices. Travelers to certain regions with a higher risk of cholera, such as parts of Africa, Asia, and Latin America, should be aware of the disease and take necessary precautions.
The symptoms of cholera can range from mild to severe and typically include profuse watery diarrhoea, vomiting, and dehydration. Without prompt treatment, cholera can rapidly lead to severe dehydration, electrolyte imbalances, and even death. It is crucial for travellers to take preventive measures, including vaccination and practicing safe food and water hygiene, to reduce the risk of contracting cholera during their journeys.
How you can contract Cholera?
Cholera is primarily contracted through the ingestion of food or water contaminated with the bacterium Vibrio cholerae. This contamination often occurs in areas with poor sanitation and inadequate access to clean drinking water. The bacterium can be present in faeces of infected individuals, and it can contaminate water sources such as rivers, lakes, or wells, as well as food products grown or washed with contaminated water.
​
When a person consumes the contaminated food or water, the bacteria multiply in the intestines, releasing toxins that cause severe diarrhoea. Cholera is highly contagious, and it can spread rapidly in communities and crowded places, such as refugee camps or areas with poor hygiene practices. Person-to-person transmission is uncommon, but it can occur if proper hygiene measures are not followed, especially in the handling of faecal matter or contaminated items.
​
Travellers to regions with a higher prevalence of cholera should be particularly cautious. It is crucial to ensure the safety of drinking water by using bottled water, purifying water through boiling or using water filters, and avoiding ice made from tap water. Additionally, practicing good hand hygiene, such as frequent handwashing with soap and water or using alcohol-based hand sanitisers, can significantly reduce the risk of contracting cholera.
Symptoms of Cholera
Profuse diarrhoea: Cholera is characterised by severe watery diarrhoea. The stool appears like rice water and is odourless. It can lead to rapid and extreme fluid loss, resulting in dehydration.
​
Vomiting: Cholera often causes uncontrollable vomiting, which can further contribute to dehydration and electrolyte imbalances.
Dehydration: Due to the excessive loss of fluids through diarrhoea and vomiting, dehydration is a significant symptom of cholera. It can lead to symptoms such as extreme thirst, dry mouth, decreased urine output, and lethargy.
​
Muscle Cramps: Cholera can cause painful muscle cramps, particularly in the legs and abdomen. These cramps can be intense and are often associated with the loss of essential minerals and electrolytes.
​
Rapid Heartbeat and Low Blood Pressure: As cholera severely dehydrates the body, it can lead to a rapid heartbeat (tachycardia) and low blood pressure (hypotension). These symptoms can result in weakness, dizziness, and fainting.
​
Prompt medical attention is crucial if you experience any of these symptoms, as untreated cholera can quickly become life-threatening. Rehydration therapy, antibiotics, and other supportive measures are vital in managing cholera and preventing severe complications.
How is Cholera Treated?
The treatment for cholera focuses on rehydration and restoring the body's electrolyte balance. Prompt rehydration can greatly reduce the risk of complications and death associated with cholera.
The primary treatment approach is oral rehydration therapy, which involves drinking a solution of clean water and oral rehydration salts that contain a balanced mixture of sugar and electrolytes. This helps replace the fluids and electrolytes lost through diarrhoea.
In severe cases or when oral rehydration therapy is not feasible, intravenous fluids may be administered to rapidly rehydrate the body. Antibiotics may also be prescribed to reduce the duration and severity of cholera symptoms, although they do not replace the need for rehydration.
In addition to treatment, proper sanitation and hygiene practices are crucial in preventing the spread of cholera. This includes access to clean water, adequate sanitation facilities, and practicing good hand hygiene.
It is important to seek medical attention promptly if you suspect cholera or experience symptoms such as profuse watery diarrhoea, vomiting, and dehydration. Early treatment can help prevent complications and improve the chances of recovery.
How to prevent Cholera?
Preventing cholera primarily involves practicing good hygiene, ensuring access to clean water, and adopting safe food handling practices. Here are some measures to prevent cholera:
-
Safe water and sanitation: Drink clean and safe water from reliable sources. If the quality of water is uncertain, boil it or use water disinfection tablets or filters. Avoid consuming ice made from untreated water. Use proper sanitation facilities and promote proper sewage disposal to prevent contamination of water sources.
-
Hand hygiene: Wash your hands thoroughly with soap and clean water, especially before eating or preparing food, and after using the toilet. If soap and water are not available, use alcohol-based hand sanitizers containing at least 60% alcohol.
-
Food safety: Consume only properly cooked and hot foods. Avoid raw or undercooked seafood, raw fruits and vegetables (unless they have been washed with clean water and peeled), and unpasteurized dairy products. Ensure that food is stored and handled properly to prevent contamination.
-
Vaccination: Consider getting vaccinated against cholera if you are traveling to an area with a high risk of cholera transmission. Cholera vaccines are available and can provide some protection against the disease.
-
Proper waste management: Dispose of waste properly to prevent contamination of water sources and the spread of diseases. Encourage community-wide efforts to improve sanitation and waste management practices.
-
Education and awareness: Stay informed about cholera prevention measures and educate yourself and others on good hygiene practices. Promote community awareness programs on cholera prevention and encourage others to adopt preventive measures.
By following these preventive measures, you can significantly reduce the risk of contracting and spreading cholera.
Countries that have Cholera
The top countries/regions where cholera is commonly found include:
Sub-Saharan Africa: Cholera remains endemic in many countries in this region, including countries such as Somalia, Democratic Republic of Congo, and Mozambique.
South Asia: Cholera is prevalent in countries like Bangladesh and India, where overcrowded urban areas and inadequate sanitation contribute to the spread of the disease.
Southeast Asia: Countries such as Indonesia and Myanmar have reported cases of cholera, particularly in areas with limited access to clean water and sanitation facilities.
Haiti and other parts of the Caribbean: Cholera outbreaks occurred in Haiti following the devastating earthquake in 2010, and sporadic cases continue to be reported in the region.
Yemen: Yemen has been experiencing a severe cholera outbreak since 2016, exacerbated by conflict and disruption of water and sanitation infrastructure.
It is important to note that cholera can also occur sporadically or in localised outbreaks in other regions and countries. Travellers to areas with a high incidence of cholera should take necessary precautions, such as practicing good hygiene, avoiding contaminated food and water, and considering cholera vaccination. It is advisable to consult with healthcare professionals or travel health clinics for personalised advice and recommendations before traveling to regions where cholera is common.
