I don't know that I contracted this on the trail but I suspect I did. My right eye slowly became blurred and I assumed it was a cataract. I delayed seeing an Opthamologist after my thru as I spent 4 months skiing away from home. I have a rather severe case of toxoplasmosis and am being treated with antibiotics and steroids. Switching to eye injections this week.
My research of the Google variety shows that this is usually contracted from cats and I have never had cats. More recently it is believed that it can be contracted from contaminated water supply. My question to anyone who might know; Is the parasite Toxoplasmosis Gandii (hope I have it spelled correctly) killed or inactivated by Aqua Mira, boiling and steripen.?
My best guess - and its only a guess, is that I contracted it from water on the trail. I used Aqua Mira throughout my hike, occasionally only boiled water when I was making a hot drink and for about a month I shared a friends steripen to make safe. I drank untreated only when the spring flowed strongly straight out of the side of the mountain or through a pipe in the side of the mountain.
Again I dont know that I got this from water on the trail but all of the other ways of getting this seem very unlikely for me.
