| The majority of immuno-competent individuals suffer a short (less than 2 weeks) self limiting course that requires supportive care with re-hydration and occasionally anti-diarrhoeal medication. In immuno-incompetent individuals (including some with [[HIV]]/[[AIDS]]) anti-retroviral therapy has been associated with improved outcomes. Several drug trials with high dose [[azithromycin]] look promising.

| ==Infectious agents== | | [[Cryptosporidiosis case study one|Case #1]] |
| A number of species of ''Cryptosporidium'' infect mammals. In humans the main causes of disease are ''[[Cryptosporidium parvum|C. parvum]]'' and ''C. hominis'' (previously ''C. parvum'' genotype 1). ''C. canis'', ''C. felis'', ''C. meleagridis'', and ''C. muris'' can also cause disease in humans.

| * In 1993 a waterborne cryptosporidiosis outbreak occurred in Milwaukee, Wisconsin. An estimated 403,000 people became ill, including 4,400 people hospitalized.<ref name=Corso_2003>{{cite journal | author = Corso P, Kramer M, Blair K, Addiss D, Davis J, Haddix A | title = Cost of illness in the 1993 waterborne Cryptosporidium outbreak, Milwaukee, Wisconsin. | journal = Emerg Infect Dis | volume = 9 | issue = 4 | pages = 426-31 | year = 2003 | id = PMID 12702221}}</ref>
| |
| | |
| * In the summer of 2005, after numerous reports by patrons of gastrointestinal upset, a water park at Seneca Lake State Park, in the Finger Lakes region of upstate New York, was found to have two water storage tanks infected with ''Cryptosporidium''. By early September of 2005, over 3,800 people reported symptoms of a ''Cryptosporidium'' infection.<ref>{{cite web | title=State Health Department Issues Update on Seneca Lake State Park Gastrointestinal Outbreak | work=New York State Health Dept | url=http://www.health.state.ny.us/press/releases/2005/2005-09-01_school_precautions_seneca_lake_release.htm | accessdate=2006-09-29}}</ref> The "Sprayground" was ordered closed for the season on August 15.
| |
| | |
| * In October 2005 Gwynedd and Anglesey areas of North Wales (UK) suffered an outbreak of Cryptosporidiosis. The outbreak may be linked to the drinking water supply from Llyn Cwellyn but this is yet to be confirmed. This has resulted in over 200 people falling ill and the company Welsh Water (Dwr Cymru) advising 61000 people to boil their water before use.
| |
| | |
| *The UK's biggest outbreak occurred in Torbay in Devon in 1995 when 575 people fell ill.
| |
| | |
| * In March 2007, a suspected outbreak occurred in Galway, Ireland, after the source of water for much of the county, Lough Corrib, was suspected to be contaminated with the parasite. A large population (90,000 people) including areas of both Galway City and County were advised to boil water for drinking, food preparation and for brushing teeth. On 21 March 2007, it was confirmed that the city and county's water supply was contaminated with the parasite. The area's water supply was finally given the all-clear on 20 August, 2007; five months after it was first detected. Around 240 people contracted the disease, however experts say the true figure could be anything up to 5,000. <ref>[http://www.rte.ie/news/2007/0820/galway.html RTÉ News - ''Galway water now safer than ever - HSE'']</ref>
| |
| | |
| * As of June 20, 2007, Anglian Water Services prepared an alert confirming the possibility that cryptosporidium might have entered the drinking water supply in North Walsham, Anglia, England.<ref>{{cite web | title=Anglian Water Services: alert | work=Anglian Water Services, June 20, 2007 | url=http://www.anglianwater.co.uk/index.php?sectionid=135&contentid=879&parentid=0 | accessdate=2007-06-20}}</ref>. Customers in North Walsham and in the North Walsham Road area of Felmingham are being advised to boil their tap water before drinking it or using it in cooking.

|
| |
|
| * As of August 9 2007, there is an outbreak of Crypto in Montgomery County, PA. There are 20 confirmed cases, and the Health Department is keeping close watch on local swimming pools. The Spring Valley YMCA has been under closest watch as all 20 of the cases have been to it. They have been closing the pools for extra disinfection after accidents. Other local pools have been affected and most are taking the same steps to assure safety, whether they have crypto or not.

|
| |
|
| * Hundreds of public pools in 20 Utah counties were closed to young children in 2007, as children under 5 are most likely to spread the disease, especially children wearing diapers. As of September 10, 2007 the Utah State health department had reported [http://health.utah.gov/uthealthnews/2007/20070911-Restrictions.htm 1302 cases] of cryptosporidiosis in the year; a more usual number would be 30. On September 25, the pools were re-opened to those not requiring diapers, but hyperchlorination requirements were not lifted.
