What is it?
Cryptosporidium is a protozoan or 'germ' which may cause diarrhoea. This can be quite common in the UK. The germ can cause infections in animals such as cattle, sheep, dogs and cats as well as man, however, animals may not show any symptoms of infection.
Where can it be caught?
Cryptosporidium infection can be acquired by spread from another person with diarrhoea caused by this germ. The hands, food or objects which are put to the mouth may be contaminated with the organism and cause infection. Contact with animals, especially farm animals, drinking unpasteurised milk and contact with, or drinking untreated water may also result in infection.
This germ may also be present in food, especially undercooked or raw meat products. Only a few organisms are needed to cause infection, this may be as little as 12 oocysts.
How long until symptoms develop?
It can take on average between 7 and 14 days before symptoms start. However, the very young and the elderly may develop symptoms within a few days.
What are the symptoms?
These may vary but usually consist of one or more of the following: Diarrhoea, stomach pains, fever and occasional vomiting.
How long do symptoms last?
Most people's symptoms resolve slowly and gradually after being ill for a few weeks.
Once recovered and having had no diarrhoea for 48 hours it is safe for normal work or school activities to resume, this includes dealing with food. If symptoms persist, consult your GP.
If you have any further questions regarding any of the above, please feel free to contact the Environmental Health Department on 01727 866100 extension 2450 or 2444.
Remember, if you are ill, pay particular attention to personal hygiene. Always wash your hands after visiting the toilet, and before handling food. This will help prevent the spread of infection to others.
