Cryptosporidiosis is a disease caused by a microscopic protozoan parasites of the genus called Cryptosporidium. It is primarily a food, animal contact and waterborne disease and although major outbreaks are thankfully fairly rare, the illness resulting from it can be serious and it is therefore important to try and stop it occurring wherever possible. The aim of these web pages is to provide background information on the disease, its occurrence and the control measures currently in place in the UK to deal with it.
Environmental health practitioners play a key role in monitoring and safeguarding the quality of water supplies in the UK and are instrumental in providing support and advice when an outbreak occurs. The body of knowledge about Cryptosporidium is growing fast and what we have been able to provide here is only a small part of it. We hope that you will find the pages in this section a useful introduction to the subject.
