Cholera Symptoms: Causes and Prevention

Cholera Explained: Risk Factors, Symptoms, and Prevention Tips

Cholera is a diarrheal illness caused by the bacterium Vibrio cholerae and is fatal if left untreated. It is transmitted through contaminated food and water, and its spread can result in fatal dehydration. Cholera poses a public health threat, especially among communities with poor sanitation and little access to clean drinking water. Knowledge of the symptoms, causes, and preventive measures will assist in managing the disease itself and its effect on susceptible groups.

What is Cholera?

Cholera is a severe bacterial infection of the intestines. It results in profuse, watery diarrhea, leading to severe dehydration and, in the absence of treatment, death. It is linked closely with poor sanitation, bad hygiene, and the ingestion of contaminated food and water.

This disease has been responsible for catastrophic epidemics throughout history, most notably in developing nations with poor access to clean water and healthcare. Cholera is still an international health concern today, with outbreaks in numerous regions of the globe, notably where natural disasters, conflict, or refugee crises have occurred.

How is Cholera Transmitted?

Cholera is caused primarily by the ingestion of food or water containing the Vibrio cholerae bacterium. The primary sources of infection are:

● Consuming drinking water with human feces that has Vibrio cholerae.
● Consuming raw or undercooked fish caught from contaminated waters.
● Food prepared in dirty conditions, for example, street food or food prepared by infected people.
● Bad personal hygiene habits, for instance, not washing hands before eating or after going to the toilet.

The bacteria are digested and enter the intestines, where they multiply and secrete toxins that result in cholera's distinctive symptoms.

What are the Common Symptoms of Cholera?

Early identification of cholera symptoms is important to obtain immediate medical care and avoid serious complications. The primary symptoms are:

1. Profuse Watery Diarrhea

One of the characteristic signs of cholera is acute, profuse diarrhea that is also called "rice-water stools" due to its milky, pale or slightly cloudy texture. The diarrhea may be very watery and cause fluid loss at a rapid rate.

2. Vomiting

Individuals with cholera tend to vomit quite often, which leads to dehydration as well.

3. Severe Dehydration

As a result of excess loss of fluids, dehydration happens quickly. It is indicated by:

●  Dryness of the mouth and intense thirst
●  Sunken eyes
●  Reduced urine production
●  Dry and wrinkled skin
●  Fast pulse and decreased blood pressure

4. Muscle Cramps and Weakness

Dehydration and electrolyte disturbances may lead to cramping of muscles, weakness, and dizziness.

5. Shock and Coma (Severe Cases)

In the worst possible instances, untreated cholera may cause hypovolemic shock, organ failure, and even death.

What are the Causes of Cholera?

The primary causative agent for cholera disease is the bacterium Vibrio cholerae, which secretes an intestinal toxin. In this regard, the major factors contributing to cholera are:

1. Contaminated Water

Consuming untreated water from polluted sources like lakes, rivers, or wells is the prime reason for the outbreak of cholera.

2. Poor Sanitation and Hygiene

Lack of proper disposal of sewage, poor handwashing, and inappropriate sanitation account largely for the spread of cholera.

3. Consuming Contaminated Food

Consumption of food cooked in unhygienic environments, such as raw or undercooked fish and seafood, unclean fruits, and inadequately stored food, may result in infection.

How do Doctors Diagnose and Treat Cholera?

Diagnostic Methods for Cholera

Cholera is diagnosed by:

●  Analysis of a stool sample for Vibrio cholerae.
●  Rapid diagnostic tests (RDTs).
●  Blood tests are required in major cases.

Cholera Treatment Options

Immediate treatment is essential to prevent complications. The main treatment options include:

1. Oral Rehydration Therapy (ORT)

●  The main treatment for cholera is oral rehydration solution (ORS), which restores lost fluids and electrolytes.

2. Intravenous (IV) Fluids

●  In acute situations, IV fluids are used to avoid dehydration shock.

3. Antibiotics

●  In certain instances, antibiotics like doxycycline or azithromycin can be given to reduce the duration of diarrhea.

4. Zinc Supplements

●  Zinc supplementation may decrease the duration and severity of diarrhea, particularly in children.

What are the best Methods for Cholera Prevention?

The prevention of cholera is important to control outbreaks. Here are the major prevention strategies:

1. Drink Safe Water

●  Always drink bottled, boiled, or filtered water.
●  Use the tap for toilet use only and never drink its water.
●  Tap water and ice should be avoided wherever the risk level is high.

2. Maintain Proper Hygiene

●  Wash hands often with soap and clean water.
●  Do not touch your face and mouth with dirty hands.

3. Food Safety Measures

●  Consume freshly prepared food.
●  Do not consume raw or undercooked seafood and raw vegetables.

4. Sanitation and Waste Management

●  Dispose of human waste properly.
●  Maintain toilets, clean them regularly and keep them in good condition.

5. Cholera Vaccination

●  Oral cholera vaccines, e.g., Dukoral, Shanchol, and Euvichol-Plus, give short-lived protection against the disease.

What are the 10 Ways to Prevent Cholera?

1.Use only safe, treated, or bottled water for drinking.
2.Wash hands regularly with clean soap and water.
3.Cook food well and consume it hot.
4.Do not use raw and unwashed fruits and vegetables.
5.Practice good personal hygiene.
6.Make use of clean, well-maintained sanitation facilities.
7.Dispose of waste properly and hygienically.
8.Avoid eating from unhygienic street stalls.
9.Get vaccinated before travelling to cholera-endemic regions.
10.Educate people in communities on cholera prevention and good hygiene practices.

Cholera is an ever-present global health threat, especially in areas of poor sanitation and limited availability of clean water. Public awareness, prompt detection, and preventive actions can immensely decrease the possibility of infection and prevent fatalities. 
The public and communities can fight this fatal disease by maintaining clean drinking water and sanitary facilities and providing proper medical care at the right time.
