Access to clean drinking water is a basic human right, yet many people around the world are forced to drink from contaminated sources. This exposes them to a range of deadly waterborne diseases that can cause severe illness and even death. Understanding the dangers of drinking dirty water can help advocate for improved water quality worldwide.
1. Cholera
Cholera is caused by the Vibrio cholerae bacterium if ingested through food or water. It impacts people in areas with poor sanitation, where sewage mixes with drinking water supplies. The primary symptoms are voluminous diarrhea and vomiting, leading to severe dehydration. Cholera can cause such extreme fluid loss that it can kill within hours if not promptly treated. While most cases can be successfully treated with oral rehydration therapy, providing access to rehydration treatment in impoverished areas remains a challenge. Improving sanitation infrastructure and water treatment in vulnerable regions is key to controlling cholera outbreaks.
2. Cancer
Cancer is not commonly thought of as a waterborne disease, but contaminated water can increase cancer risk. Water pollution from industrial chemicals, pesticides, heavy metals, and nitrates can contain carcinogens. These cancer-causing contaminants enter ground and surface water supplies from industrial effluent, agricultural runoff, and sewage discharge. Over time, exposure through ingestion or absorption during bathing/showering increases cancer risk. Some water contaminants like arsenic and chromium are carcinogenic. Others, like nitrates, can transform into carcinogenic compounds in the body. A prime example is the water contamination at Camp Lejeune that exposed thousands of marines and their families to carcinogens, leading to increased cancer rates that veterans are still battling today. If you are a veteran harmed due to the contaminated water at the base, organizations like www.camplejeuneclaimscenter.com can help you file a claim to get the financial benefits that you deserve.
3. Typhoid Fever
Typhoid fever is another bacterial disease transmitted by contaminated food or water. It is caused by the Salmonella typhi bacteria and is a major health threat in developing nations with unsafe water and inadequate sanitation. After the bacteria are ingested, they multiply and spread through the bloodstream. Symptoms include sustained high fever, stomach pains, headache, and loss of appetite. Typhoid can also produce intestinal perforation and internal bleeding. While antibiotics can treat typhoid fever, multi-drug-resistant strains are a growing problem. Preventative strategies include improving community hygiene and water quality. New typhoid vaccines also show promise for disease control.
4. Hepatitis A
The hepatitis A virus is a common cause of waterborne illness outbreaks worldwide. It spreads easily through contaminated food and water and thrives in areas with poor sanitation and hygiene. Hepatitis A initially causes inflammation of the liver, leading to symptoms like fever, fatigue, nausea, and jaundice. Although most recover fully, hepatitis A can occasionally progress to liver failure and death. This is especially true for those with underlying liver disease. Improved sanitation helps control hepatitis A transmission, but vaccination is the most effective prevention strategy, providing active immunization and protection.
5. Giardiasis
Giardiasis is an intestinal infection caused by the microscopic Giardia parasite. It is one of the most frequent waterborne diseases globally. Giardia spreads through water or food sources contaminated with infected feces. Upon ingestion, the parasite attaches to the intestines and causes diarrhea. Other giardiasis symptoms include excessive gas, greasy stools, stomach cramps, and weight loss. Giardiasis can also lead to malabsorption and deficiencies of essential nutrients. While normally self-limiting, giardiasis causes recurring episodes in a subset of individuals. Preventing contamination of drinking water supplies with sewage and proper treatment of drinking water are key control measures.
6. E. coli Infection
Escherichia coli (E. coli) bacteria are a frequent cause of waterborne disease outbreaks. While most E. coli strains are harmless, some, like O157:H7, can cause severe illness. Contaminated water sources, raw produce, and undercooked meat can transmit pathogenic E. coli. Symptoms include severe diarrhea, vomiting, and painful stomach cramps. In some cases, E. coli infection leads to a type of kidney failure called hemolytic uremic syndrome. This is particularly dangerous in young children and older adults. Preventing fecal contamination of food and drinking water supplies is important to stop the spread of E. coli. Proper handwashing after using the bathroom and before food preparation is also key.
7. Amoebic Dysentery
Amoebic dysentery is caused by the parasite Entamoeba histolytica. It is prevalent in areas with poor sanitation and contaminated water. The parasite is ingested from tainted food or water sources and then invades the intestinal lining. This leads to symptoms like severe stomach pain, bloody diarrhea, fever, and chills. In some cases, the parasite spreads from the intestines to other tissues like the liver, lungs, and brain, causing severe complications. The most serious complication is an amebic liver abscess, which can be fatal if left untreated. While better sanitation helps control the spread, health education programs are also needed. These teach proper handwashing and food preparation techniques to prevent ingestion.
8. Rotavirus
Rotavirus is the leading viral cause of severe diarrhea among infants and children globally. It spreads easily from contaminated surfaces, food, and water. Once ingested, the virus invades and damages the intestinal lining cells, impairing nutrient absorption. Common symptoms include fever, vomiting, and watery diarrhea. Rotavirus diarrhea can lead to dangerous dehydration and death, especially in developing nations lacking access to rehydration therapy. Over 200,000 children under five die from rotavirus each year. Promoting handwashing, safe drinking water, and rotavirus immunization are all essential prevention strategies. New rotavirus vaccines have had a huge public health impact, but access in poor nations remains a challenge.
Preventing Waterborne Diseases
A. Methods to make water safe
- Boiling: Bringing water to a rolling boil kills most disease-causing microbes. This is effective but requires fuel sources that are often scarce in low-income regions.
- Chemical Disinfection: Adding chlorine or iodine can kill bacteria and viruses when done correctly. However, some parasites like Cryptosporidium are resistant.
- Filtration: Filters with tiny pores physically trap microbes. Filter effectiveness varies – advanced filters like ultrafilters or reverse osmosis remove more pathogens.
B. Improving sanitation and hygiene
- Safe disposal of human waste keeps feces from contaminating water supplies. Proper toilets, latrines, and sewage infrastructure must be built and used.
- Handwashing with soap after toileting or before eating removes disease-causing microbes from hands and prevents spread.
- Proper storage of drinking water in covered containers protects it from recontamination by hands, animals, dirt, etc. Even safe water can become dangerous again when stored unsafely.
- Health education programs teach community members about pathogens, hygiene, and safe practices to prevent waterborne diseases.
- Holding authorities and corporations responsible for the safe disposal of industrial wastes and preventing chemical contamination of water supplies.
- Demanding policy change at local, state, and national levels to properly regulate the discharge of chemicals by industries and farms.
- Taking legal action to help victims of chemical pollution obtain financial benefits for health costs and other losses.
Conclusion
Lack of access to clean water facilitates the spread of numerous dangerous diseases that can sicken or kill vulnerable populations. Improving community water supplies, sanitation infrastructure, and hygiene practices is critical. However, global action is urgently needed to help equip impoverished nations with the resources and technology required to provide their citizens with safe drinking water. This will help eradicate many preventable waterborne illnesses that have plagued humanity for too long. Clean water access for all is an essential goal of a just and equitable society.
