Protozoan Parasites

Protozoan parasites are single-celled organisms which can cause a range of diseases in humans, ranging from mild diarrhoea to the deadly malaria. Protozoans, such as Giardia and Cryptosporidium, can spread through contact with contaminated water and food, leading to waterborne disease. Infections caused by protozoan parasites can be treated with a range of drug combinations, and improved water, sanitation and hygiene practices are important for prevention. Understanding how protozoan parasites are spread and how to identify, treat and prevent their transmission is essential for public health and food safety.
