Question

suggest any two ways to prevent being infected by protozoa

Answer 1

One way is to wash your hands regularly, especially after handling uncooked food or feces.

Many protozoan infections can be prevented. Modern sanitary methods can limit the contamination of food and water with the single-celled parasites, called protozoa, which cause the condition. If you are visiting an area known to have contaminated water, boil it before use to destroy any parasites.
