Giardia is a microscopic parasite that can potentially cause gastrointestinal illness. It is found in water sources such as lakes, streams, and rivers, and can also be transmitted from person to person through contact with feces. Symptoms of giardiasis include diarrhea, abdominal cramps and pain, nausea, dehydration, fatigue, weight loss, and greasy stools.

If you’re a hiker, camper, or someone who plans to visit areas with potentially contaminated water sources, it is important to take precautions by purifying your drinking water. Some methods of purification include boiling the water before use, using chemical treatments like iodine and chlorine dioxide tablets, and filtering it with specialized water filters.

The survival of humans in the wild depends on access to clean, safe drinking water. But if you’re stuck in an area with contaminated water sources, it is important to take the necessary steps to protect yourself from giardia and other potentially dangerous parasites. Remember that boiling, chemical treatments, and filtering can all help to purify the water and reduce your risk of becoming ill. With proper preparation and safety precautions, you can ensure a safe and successful outdoor experience.
