:It kills bacteria, protazoa (including cryptosporidium), and viruses, without leaving a taste in the water.
How does this compare to the Wilderness Medicine book on the use of povidone iodine (often referred to by the brand name of "Betadine").Betadine solution (NOT scrub, which has soap in it) is an excellent wound cleansing agent. It should be diluted 1 part in 10 parts water (obviously clean water) before using, as full strength Betadine is indeed somewhat harsh on tissue.
Another use is water purification. 10 drops Betadine solution in one liter of water will kill bacteria, Giardia and amoeba.

Chlorine dioxide is one of the more effective treatments for crypto known. It is used to treat many municipal water supplies. Here is a link to a study about its effectiveness:Sounds good, is there some scientific proof that it kills Cryptosporidium? That seems to be the only weak point to many of the chemical treatments.
