Giardia: The Microscopic Parasite that Spreads through Contaminated Water
Giardia is a microscopic parasite that is transmitted through infected feces. However, unlike other parasites, contaminated water is the primary source of human illness in the case of giardia. What makes this parasite particularly dangerous is its ability to survive outside the body for weeks. Additionally, its protective shell enables it to withstand the corrosive effects of chlorine, allowing it to thrive even in chlorinated bodies of water. To safeguard against giardia infection, it is crucial to refrain from drinking pond or pool water.
Cryptosporidium: The Waterborne Parasite
Cryptosporidium, also known as crypto, is a parasite that can lead to a diarrheal illness when consumed, typically through contaminated water sources. Similar to giardia, crypto possesses a protective shell that allows it to survive outside of the human body for extended periods. While it usually does not pose a significant threat to individuals with robust immune systems, it remains one of the primary waterborne contaminants in the United States. However, for those with weakened immune systems, such as immunocompromised individuals, crypto can result in more severe complications. Fortunately, most people are able to recover from crypto with the aid of fluids.
