Top 10 Water-Borne Diseases and How to Avoid Them

Imagine you're on a week-long hiking trip through the Appalachian Trail. You've packed all the essentials—food, shelter, first aid—but halfway through, you realize you forgot one crucial item: a reliable method to ensure your drinking water is safe. This oversight can turn a dream adventure into a nightmare if you fall victim to a water-borne disease. Clean water is critical for maintaining health and safety, especially for survivalists, outdoor enthusiasts, and anyone committed to emergency preparedness. This blog aims to educate you on the top 10 water-borne diseases and how to effectively avoid them, ensuring your outdoor adventures remain enjoyable and safe.

How Water-Borne Diseases Come About:

Water-borne diseases are infections caused by pathogenic microorganisms that are transmitted in water. These pathogens, including bacteria, viruses, and parasites, thrive in contaminated water sources. They can enter the human body through ingestion, skin contact, or inhalation of contaminated water droplets. Common causes of water contamination include:

Human and Animal Waste: Poor sanitation and inadequate sewage treatment can lead to water contamination with fecal matter containing harmful microorganisms.
Agricultural Runoff: Pesticides, fertilizers, and animal waste from farms can wash into rivers, lakes, and groundwater, introducing pathogens.
Industrial Pollution: Factories and industrial plants may release harmful chemicals and waste products into water sources, contributing to contamination.
Natural Disasters: Floods, hurricanes, and other natural disasters can disrupt sanitation systems and contaminate water supplies with debris and pathogens.

Here are 10 of the most common waterborne diseases :

1. Cholera

Overview: Cholera is a severe bacterial infection caused by Vibrio cholerae. It is often associated with large outbreaks in areas with poor sanitation and contaminated water supplies.

Transmission: Cholera spreads through ingestion of contaminated water and food.

Prevention:

Use portable water filters to remove bacteria.
Boil water before drinking or cooking.
Practice good hygiene by washing hands frequently and ensuring food is prepared safely.

2. Dysentery

Overview: Dysentery is an infection of the intestines, resulting in severe diarrhea with blood. It can be caused by Shigella bacteria or amoebas (amoebic dysentery).

Symptoms: Bloody diarrhea, abdominal pain, and fever.

Transmission: Contaminated water, food, and poor sanitation practices.

Prevention:

Filter and boil water before use.
Avoid unclean food sources such as food that has not been properly cooked or raw produce.
Maintain good hand hygiene.

3. Giardiasis

Overview: Giardiasis is a parasitic infection caused by Giardia lamblia. It is one of the most common water-borne diseases affecting travelers and outdoor enthusiasts.

Symptoms: Diarrhea, gas, stomach cramps, and nausea.

Transmission: Ingesting water or food contaminated with Giardia parasites.

Prevention:

Use portable water filters designed to remove protozoa.
Avoid drinking untreated water from streams and lakes.
Ensure proper sanitation and hygiene.

4. Cryptosporidiosis

Overview: Cryptosporidiosis is caused by Cryptosporidium parasites, which are highly resistant to chlorine and can survive in various water sources.

Symptoms: Watery diarrhea, stomach cramps, and weight loss.

Transmission: Consuming contaminated water, particularly from pools and natural water sources.

Prevention:

Use water filters that remove parasites.
Avoid swallowing water from pools, lakes, or rivers.
Practice good hygiene, especially after handling animals.

5. Hepatitis A

Overview: Hepatitis A is a viral infection affecting the liver, caused by consuming contaminated food or water.

Symptoms: Jaundice, fatigue, stomach pain, and loss of appetite.

Transmission: Contaminated water and food.

Prevention:

Get vaccinated against hepatitis A.
Use filtered and boiled water for drinking and cooking.
Practice good personal hygiene.

6. E. coli Infection

Overview: E. coli infection is caused by Escherichia coli bacteria, some strains of which can lead to severe gastrointestinal illness.

Symptoms: Severe stomach cramps, diarrhea (often bloody), and vomiting.

Transmission: Contaminated water and food.

Prevention:

Ensure water is properly filtered and treated.
Avoid consuming raw or undercooked food from unclean sources.
Practice good hygiene to prevent contamination.

7. Typhoid Fever

Overview: Typhoid fever is a serious illness caused by Salmonella typhi bacteria, often linked to contaminated water and poor sanitation.

Symptoms: High fever, weakness, stomach pain, and loss of appetite.

Transmission: Contaminated water and food.

Prevention:

Get vaccinated against typhoid fever.
Use reliable water filtration methods.
Maintain proper sanitation and hygiene.

8. Norovirus

Overview: Norovirus is a highly contagious virus that causes gastroenteritis, leading to severe vomiting and diarrhea.

Symptoms: Severe vomiting, diarrhea, stomach pain, and fever.

Transmission: Contaminated water, food, and surfaces.

Prevention:

Use filtered and treated water.
Practice rigorous hand hygiene.
Avoid contaminated food sources.

9. Leptospirosis

Overview: Leptospirosis is a bacterial infection caused by Leptospira, commonly found in floodwaters and areas with poor sanitation.

Symptoms: High fever, headache, muscle aches, and vomiting.

Transmission: Contact with contaminated water, particularly in floodwaters.

Prevention:

Avoid swimming or wading in potentially contaminated water.
Use water filters and treat water before consumption.
Wear protective clothing in high-risk areas.

10. Legionnaires' Disease

Overview: Legionnaires' disease is caused by Legionella bacteria, which thrive in stagnant water and can be inhaled through water droplets.

Symptoms: Severe pneumonia, fever, cough, and muscle aches.

Transmission: Inhalation of contaminated water droplets.

Prevention:

Avoid stagnant water sources.
Use water treatment and filtration systems.
Regularly clean and maintain water systems.
Important Fact: During 2015–2020, Legionella-associated outbreaks continued to increase and were the leading cause of nationally reported drinking water-related outbreaks, hospitalizations, and deaths.

General Strategies for Preventing Water-Borne Diseases

Ensuring safe drinking water is crucial for avoiding water-borne diseases. Here are some effective strategies to protect yourself:

Portable Water Filters:

Explanation: Using portable water filters, such as Survivor Filters, helps remove bacteria, protozoa, and other contaminants from natural fresh water sources. These filters are designed to make water safe for drinking, reducing the risk of water-borne diseases during outdoor adventures and emergencies.
Tip: Always carry a reliable portable water filter when hiking, camping, or traveling to areas with questionable water quality.

Boiling Water:

Explanation: Boiling water is one of the simplest and most effective methods to kill pathogens, including bacteria, viruses, and parasites. Boiling for at least one minute at a rolling boil ensures that the water is safe to drink.
Tip: In high-altitude areas, where water boils at a lower temperature, extend the boiling time to three minutes.

Chemical Treatment:

Explanation: Chemical treatments, such as chlorine or iodine tablets, can purify water by killing harmful microorganisms. These tablets are lightweight, portable, and easy to use, making them a convenient option for emergency water disinfection.
Tip: Follow the manufacturer's instructions for dosage and wait time to ensure effective purification.

Hygiene Practices:

Explanation: Good hygiene practices are essential to prevent the spread of water-borne diseases. Washing hands with soap and water frequently, especially after using the toilet and before handling food, can significantly reduce the risk of infection.
Tip: Carry hand sanitizers for situations where soap and water are not available.

Safe Food Handling:

Explanation: Proper food handling and storage are critical to prevent contamination. Ensure food is cooked to safe temperatures and avoid consuming raw or undercooked foods. Store food in clean, sealed containers to keep it free from contaminants.
Tip: Avoid using untreated water to wash fruits and vegetables. Instead, use filtered or boiled water.

By incorporating these strategies into your routine, you can greatly reduce the risk of water-borne diseases and enjoy safer outdoor and emergency experiences.

Clean water is essential for health and survival, especially in outdoor and emergency situations. By understanding the risks of water-borne diseases and employing effective prevention strategies, you can protect yourself and your loved ones.
