Cholera: Signs and Symptoms, Causes and Treatment

Cholera Overview

Cholera, a bacterial disease primarily transmitted through contaminated water, poses a significant health risk, causing severe diarrhea and dehydration. While advanced sanitation systems have largely eradicated cholera in developed nations, its presence persists in regions facing challenges like poverty, conflict, or natural disasters.

Symptoms and Causes of Cholera

Cholera symptoms include sudden and severe diarrhea, vomiting, and dehydration. The Vibrio cholerae bacterium responsible for cholera can be present in the stool of infected individuals, contaminating water sources and perpetuating the spread of the disease. The risk is particularly high in crowded and unsanitary conditions.

Dehydration and Complications

The hallmark of cholera is rapid dehydration, with severe cases leading to a loss of body weight exceeding 10%. Symptoms of dehydration encompass irritability, fatigue, sunken eyes, dry mouth, extreme thirst, reduced urine output, low blood pressure, and irregular heartbeat. In severe cases, an electrolyte imbalance can cause muscle cramps, shock, and even death.

Cholera Treatment and Prognosis

Cholera is treatable, and timely intervention with rehydration solutions can prevent fatalities. Treatment focuses on addressing the underlying cause, whether it be refractive errors, dry eye conditions, or more severe cases related to infections.

Risk Factors

Cholera can affect anyone, but certain factors increase vulnerability. Poor sanitary conditions, reduced stomach acid levels, household exposure to an infected person, blood type O, and consumption of raw or undercooked shellfish heighten the risk.

Prevention and Vaccination

Preventing cholera involves practicing good hygiene, ensuring the safety of water sources, and consuming thoroughly cooked food. Handwashing, using safe water for drinking and food preparation, and avoiding street food are essential precautions. Vaccination, such as the cholera vaccine Vaxchora, is recommended for travelers visiting affected areas.


While cholera is rare in developed countries like the United States, it remains a threat in various parts of the world. Understanding the symptoms, risk factors, and preventive measures is crucial for individuals in both affected regions and those planning to travel to such areas. Combining vaccination with hygienic practices significantly reduces the risk of contracting and spreading cholera, contributing to global health efforts.
