Cryptosporidiosis is a gastrointestinal illness caused by protozoa of the genus Cryptosporidium, whose taxonomy continues to evolve.
In immunocompetent persons, cryptosporidiosis is characterized by weight loss, abdominal pain, diarrhea, which can be profuse, usually nonbloody, and watery, as well as anorexia, fatigue, joint pain, headache, fever, and vomiting (5). However, asymptomatic infection also can occur (6–9). Recurrence of symptoms after seeming resolution has been frequently reported; illness is self-limiting, and symptoms most frequently completely resolve within 2–3 weeks (5).
- Crypto often comes straight through our water municipalities since 90% of the municipalities in the U.S. only filter down to 7 or 8 microns. To filter out Crypto you must be able to filter down to 2 microns.
- While our lab continues to work on a solution to this problem we strongly urge all pool owners to only use DE and Sand Filtration Systems and to backwash on a regular basis. Also remember to replace DE powder each time in DE Filtration Systems.
- Swimming pools provide a tremendous amount of fun and enjoyment for everyone but remember an ounce of preventative is worth a pound of cure. Let’s work together to keep our pools a fun and safe environment.
