Giardia and Cryptosporidium are microscopic parasites that cause intestinal illness and can be transmitted in a number of ways:
Some people may be at greater risk from Cryptosporidium and Giardia than the general population. People that have undergoing chemotherapy, organ transplants or dialysis; and those with HIV/AIDS can be at a greater risk of infection. Symptoms of infection can include:
These symptoms can come and go, but usually last no longer than 30 days. A small number of people go on to develop chronic giadiasis, causing persistent or repeated bouts of diarrhoea lasting for up to two years.
