Detailed explanation-1: -Transmission of protozoa that live in a human’s intestine to another human typically occurs through a fecal-oral route (for example, contaminated food or water or person-to-person contact).

Detailed explanation-2: -Faecal-orally transmitted parasites are those parasites which are spread through faecal contamination of food and drinks. Infections with these parasites are among the most common in the world being responsible for considerable morbidity and mortality, especially in children.

Detailed explanation-3: -The most common way people get sick is by swallowing contaminated drinking water or recreational water (for example, lakes, rivers, or pools). Find answers to frequently asked questions about Giardia. Giardia infection can cause no symptoms, short-term symptoms, or long-term symptoms.

Detailed explanation-4: -Main causes of fecal–oral disease transmission include lack of adequate sanitation (leading to open defecation), and poor hygiene practices. If soil or water bodies are polluted with fecal material, humans can be infected with waterborne diseases or soil-transmitted diseases.

Detailed explanation-5: -These parasites can be spread when someone swallows water that has been contaminated with fecal matter from an infected person or animal. Individuals with compromised immune systems who come into contact with these parasites can also be at greater risk for serious illness.
