Waterborne diseases are diseases that are transmitted by ingesting contaminated water, food and contact with faeces that contain harmful bacteria, viruses and other disease causing microorganisms.
Most common waterborne disease symptoms include:
“Waterborne disease is a disease transmitted through water which is contaminated and if you ingest water from unclean sources such as public tanks, lakes or tap water (which is often contaminated in India), you might get infected with waterborne disease. From Gastroenteritis to typhoid and amoebiasis, there are a number of health conditions that can occur due to consumption of contaminated water.”
– Dr. Pragnya Rao, General Physician
Common causes of waterborne diseases
There are two major causes of water borne diseases:
(i) Waterborne pathogens such as viruses and bacteria that are ingested through contaminated water
(ii) Contact with waste products such as faeces through contaminated water.
If you ingest water from unclean sources such as public tanks, lakes or tap water (which is often contaminated in India), you might get infected with waterborne disease.
There are different types of waterborne diseases, most of which are caused by chemical pollution of water bodies due to the effect of increased levels of nitrates and heavy metals on the body. Industrial areas in India often have contaminated water
bodies because the waste from factories contains toxic materials that are dumped into nearby lakes and rivers.
According to the United Nations, over 1 lakh Indians die due to waterborne diseases every year.
Around 37.7 million Indians are affected by waterborne diseases every year, ranging from simple diarrhoea to more complicated infections. This is
mainly due to lack of access to safe drinking water and living in unsanitary conditions.
Rivers such as the Ganges provide water for nearly 500 million people in India. So contamination of even one water source can affect a large part of the population. Access to clean water is extremely important and
making sure that you boil water before drinking and using it for cooking is absolutely essential.
Most water borne diseases can be treated at an early stage. The first step to preventing serious complications from waterborne diseases is to ensure you stay hydrated. Treatment of waterborne diseases mainly includes rehydration, rest, and sometimes medication and antibiotics.
Waterborne diseases are extremely common in India and anybody can fall prey to them. Therefore, understanding the nature of these diseases and being able to identify the symptoms in time is crucial for treatment of waterborne diseases.
If you have symptoms of a possible waterborne disease, just consult a general physician on MFine
While there are a number of different kinds of waterborne diseases, there are a few which are extremely common in India and there is no collective, common water borne disease symptoms. The symptoms varies with different types of waterborne diseases.
These diseases typically occur both in rural and urban areas, so it’s important to take strict precautions no matter where you live.
Here are the symptoms and characteristics of some of the most common waterborne diseases in India.
Typhoid is a common bacterial waterborne disease caused by the Salmonella typhi bacteria. This disease is often seen in places where personal hygiene is low and
handwashing is not practised enough. According to one report, around 494 out of every 1,00,000 children in India suffer from typhoid. A lot of villages and smaller towns in India with poor sanitation face a higher risk of typhoid. However, it can also occur in urban cities during the monsoons.
Typhoid can have very serious consequences and can even be fatal if proper treatment is not administered. On average,
around 1 in every 5 cases of typhoid can be fatal. The bacteria is spread through the urine and faeces of infected people, also known as the faeco-oral transmission route. Salmonella typhi
bacteria is also passed through contaminated food and drinking water. This makes typhoid very contagious and anyone who comes in contact with an infected person can contract the disease.
Once infected, you need to be treated immediately. Any delay in treatment can have serious consequences.
Symptoms of typhoid are usually not immediately apparent. The bacterium enters the body through the mouth and then makes its way to the intestine. After around 1-3 weeks, it passes through the intestinal wall to the bloodstream. Once it enters the bloodstream, it can get passed on to other organs in
the body and it is during this period that the symptoms of typhoid become noticeable.
Some of the common typhoid symptoms include:
These are the most typical waterborne disease symptoms if you’re suffering from typhoid.
Typhoid diagnosis and treatment in India:
Typhoid is usually diagnosed through a blood test or urine samples or stool test to check for the presence of Salmonella typhi.
Once the diagnosis has been made, antibiotics are administered to battle against the infection. The patient will also be given oral fluids or an IV to rehydrate them and prevent dehydration.
If the disease has reached more advanced stages and has affected the bowels, surgical treatment might be required.
One of the reasons why typhoid is so dangerous is because the body’s immune system cannot fight against it. The bacteria resides within the cells of the host, and so the immune
system cannot attack it. Thus, prevention is the most important step in combating the prevalence of typhoid.
To prevent typhoid, you should practice the following steps:
There are also two vaccines available for typhoid – oral vaccine and injectable vaccine. Oral vaccine is given to kids below 6 years of age. Injectable vaccine is given to children under 2 years of age and 2 weeks before to people travelling to high-risk areas.
Consult a general physician on MFine if you’re experiencing Typhoid symptoms
Cholera is a waterborne disease caused by the bacterium Vibrio cholerae. It is commonly transmitted through contaminated food and faeces. According to a report by WHO, there are around 4 million cases of cholera each year. India has experienced cholera outbreaks in the past and there are still
active cases of cholera in the country. One study of an at-risk locality in Kolkata found that there were around 2.2 cases out of every 1000 people. It’s extremely important that we maintain good hygiene and sanitation to contain the spread of cholera and protect ourselves from it.
Some of the ways in which a person might contract cholera include:
Person-to-person transmission of cholera is very rare so it is unlikely that you might contract cholera from coming into contact with someone suffering from it.
Cholera is a waterborne disease that is extremely virulent and in some cases can even be life-threatening. Once a person ingests the bacteria, it reaches the intestine and starts producing toxins that cause diarrhoea.
Some of the common symptoms of cholera include
These are the most typical symptoms of cholera, a waterborne disease. You must meet a doctor immediately if you’re experiencing a combination of these symptoms.
Cholera Diagnosis and Treatment in India:
If you are experiencing symptoms of cholera, your doctor will first look at your history to check if you have travelled to any areas where cholera can spread. They will also check for other signs of cholera like reduced skin elasticity and dry mucous membranes in the nose, eyelids and mouth. If your doctor suspects a case of cholera, you will be asked to provide a stool sample.
The sample will then be examined to identify the presence of the bacteria Vibrio cholerae
Common treatment methods for cholera in India include:
Malaria fever is caused by plasmodium parasites and is transmitted by the female Anopheles mosquito that breeds on stagnant, unclean water such as lakes and sewage drains. When a carrier mosquito bites you, the parasite enters your bloodstream and goes straight to the liver, the site of RBC production. There, the parasite attacks your
RBCs and infected RBCs burst open, resulting in malaria symptoms and the onset of the disease. According to the WHO, India reports around 15 million cases of malaria each year. Sewage systems and public waterbodies, if maintained well will significantly reduce Malaria cases.
Some of the common symptoms of malaria include:
Malaria diagnosis and treatment in India:
A doctor will be able to diagnose malaria fever through a medical examination and a blood test, such as a peripheral smear to visualize the parasite and serological tests to determine the stage of the disease.
A blood test will tell you what type of malaria you have, if it’s a drug-resistant parasite, if it has resulted in anaemia and if any vital organs have been affected. A peripheral smear test is the most common method to detect malaria in the blood. A drop of the patient’s blood is smeared on a microscopic slide and is stained to identify malarial parasites. Serological tests are also done to detect antibodies against malaria.
Malaria and dengue may have similar symptoms, so you should get a test.
Malaria is treated through a series of drugs and medications as prescribed by a doctor.
To prevent contracting malaria, always practice safe hygiene protocol, install blinds in your house to prevent mosquitoes from entering and stay clear of unhygienic water sources such as sewage drains and stagnant water.
Consult a general physician on MFine if you’re experiencing Cholera or Malaria symptoms
Giardiasis is a parasitic infection caused by Giardia lamblia, a water-based pathogen, that mainly spreads through a faeco-oral contamination route and affects the small intestine. You may contact Giardia by eating contaminated food or drinking contaminated water. It is quite common in India and countries with cramped spaces and poor sanitation in communities.
Giardia lamblia is most commonly found in human and animal faeces. Swimming pools, lakes and public water bodies are the most common infection points of this water based disease. It mostly spreads when people come into contact with infected faeces.
These are the most common water borne disease symptoms of Giardiasis.
Giardiasis diagnosis and treatment in India:
Your doctor will prescribe anti-parasitic drugs to speed up the treatment process.
Amoebic dysentery is a waterborne disease that mainly spreads through contaminated food, water and contact with faecal matter. It is an intestinal infection which leads to
inflammation of the intestine as well as severe abdominal cramps and diarrhoea. Blood and mucous in the stools is common too.
Amoebic dysentery usually lasts for 3-7 days.
Diarrheal infection is located
and targets only intestinal
lumen and upper epithelial cells
Dysentery not only upper
epithelial cells are
colon ulceration also results
Amoebic Dysentery symptoms:
Amoebic Dysentery Diagnosis and Treatment in India:
Amoebic dysentery is diagnosed through a stool sample under a microscope.
A blood test and a stool test is enough to confirm dysentery. Your doctor will suggest rehydration methods to make up for all the lost fluids
from your body and will also recommend OTC medications and antibiotics if necessary.
Another common viral waterborne disease, Hepatitis A, occurs by exposure to contaminated food and water. Hepatitis A infection leads to the
inflammation of the liver and temporarily affects liver function. Fortunately, Hepatitis A is not very serious or fatal and
generally goes away on its own in a few days. However, if symptoms persist your doctor will recommend medications and antibiotics to combat the disease.
Waterborne diseases such as Hepatitis A spread when you come in contact with uncooked vegetables, contaminated food and water in unclean food joints and roadside vendors.
Hepatitis A symptoms:
Symptoms take some time to appear, usually 15-50 days after you contract the virus.
Hepatitis A diagnosis and treatment in India:
Your doctor will conduct a blood test and look for physical signs such as jaundice for Hepatitis A. There’s no hard and fast treatment for Hepatitis A. Since it goes away on its own in most cases, taking rest for a few weeks will help you recover
fully. Drink plenty of water, eat hot home-cooked meals and avoid alcohol and outside junk foods.
To get the best treatment for a Giardiasis, Dysentery or Hepatitis A, consult a general physician on MFine
Shigellosis is caused by the Shigella bacterium strain and it affects the intestine, resulting in diarrhoea and vomiting. It is a common disease that spreads through the faeco-oral route. Shigella bacteria is present in contaminated water, food and faeces.
Shigellosis commonly occurs in toddlers and school-going children, because they tend to touch dirty surfaces and put their fingers in their mouths.
More serious symptoms include:
Symptoms appear 1-3 days after exposure to the bacteria.
Shigellosis diagnosis and treatment in India:
Dehydration is the biggest issue associated with Shigellosis. It’s important to replenish
your body with fluids to ensure that you don’t lose more water. Your doctor may recommend medications and antibiotics if it’s more severe.
Amoebiasis is a water-based disease caused by the protozoan Entamoeba histolytica. It affects the intestines and causes loose stools, water
loss and stomach cramps. It usually goes away on its own with rest and rehydration.
It is waterborne and enters the body through contaminated food, drinks and faeces. When you ingest small cysts containing E.Histolytica, you will get
infected. If infected, a person can spread the disease through faecal contamination.
Amoebiasis Diagnosis and Treatment in India:
A stool test taken continuously over a few days will confirm the presence of cysts. You may also have to take a liver function test to check for any liver damage. In serious cases, a colonoscopy may be prescribed too.
To get treated for Shigellosis or Amoebiasis, consult a general physician on MFine
As you’re now aware, you can contact water borne diseases by drinking contaminated water, eating contaminated food or coming in contact with unclean
water such as swimming pools and lakes. While most conditions are treatable, it’s best if you try and prevent them altogether by practising some simple habits.
Here are some ways you can ensure you are protected from waterborne diseases:
1. Practice Environmental Hygiene:
Whenever you use a toilet, whether at home or in public, make sure you flush it well or use a bucket of water to flush it down. At home, regularly clean the toilet with
hot water and anti-bacterial detergent, preferably a chlorine-based one to keep your toilet clean and disease-free.
If possible, avoid using public bathrooms altogether. If you must, try using an Indian-style bathroom to completely avoid any contact with contaminated surfaces.
2. Practice personal hygiene:
3. Practice food safety precautions:
4. Practice good water hygiene:
The above is the most common water borne diseases list that can be avoidable by following simple hygiene standards. However, if you do contact a water-based disease, the first step you need to take is to
to get your symptoms evaluated and treated. Putting off treatment can worsen your condition and lead to severe consequences like extreme dehydration.
