Giardia in the Wilderness - Giardia and water filters

"The Giardia Horror Show, live from a stream or pool of water near you..."

Giardia is an interesting looking critter that just craves attaching itself to the lining of your intestinal wall. How quaint.


Giardia Bug

Giardia - this is the little varmint that causes so much trouble. I don't want to scare you too much, but some people get pretty sick when giardia latches on to the intestine and starts doing its thing.

The giardia lifestyle is to feed on you and then reproduce, sending potential offspring flowing out the anal canal and into the environment. In fact, as you read this, there are literally billions and billions of giardia cysts in the wild, and in cities. They wait eagerly for you to ingest them. Then you too, will become a full fledged member of the Giardia Club

The Horror of Giardia

I've had giardia making a home inside my intestines, but I've never experienced the horror part. Mine was only uncomfortable, a bit of a pain. But some people do have a time with it. You see, the symptoms vary from person to person. At least the severity of the giardia symptoms vary.

There is certainly some of the "I wish I were dead" syndrome. Unfortunately, there is no way to know in advance whether your body will react mildly to giardia, or whether it will go into full scale revolution and chaos at the introduction of the giardia organism to your system.

It would be nice if one became immune to giardia, but if that does occur, it takes generations of humans to do it. For now, you're stuck. You can catch it again, and again, and again. So after checking over the giardia symptoms, you'll want to take a look at water filters and other techniques for avoiding giardia.
