• Improved water taste

• Increased water clarity

• Enhanced nutritional value

Multiple Choice

• Eritrea

• India

• Vietnam

Open Ended

Discuss the relationship between open defecation and child stunting as shown in the data.

Multiple Select

Which of the following are consequences of poor sanitation as described in the slides?

• Transmission of diarrhoeal diseases

• Stunting in children

• Increased antimicrobial resistance

• Improved economic development

Multiple Choice

What trend is observed in the number of reports of human and animal waste in San Francisco from 2015 to 2021?

• It increased overall, peaking in 2020 before slightly decreasing in 2021.

• It steadily decreased each year.

• It remained constant throughout the years.

• It peaked in 2015 and then dropped sharply.

Open Ended

What factors might contribute to the rise in sidewalk feces in San Francisco despite a decrease in litter, as reported in the news article?

Multiple Choice

Which of the following is NOT listed as a recurring theme affecting human health in the first image?

• Clean water

• Nutrition

• Genetic engineering

• Access to healthcare

Open Ended

Based on the information from the first two images, explain how human activities and environmental changes can influence the spread of parasitic diseases.

Multiple Select

Which of the following are stages in the life cycle of Dicrocoelium dendriticum, as shown in the diagram?

• Eggs ingested by snails

• Cercariae released in slime balls

• Metacercariae eaten by ants

• Adult fluke in bile duct

Multiple Choice

What is the main difference between a monoxenous (direct) and heteroxenous (indirect) life cycle in parasites, as illustrated in the images?

• Monoxenous involves only one host, heteroxenous involves multiple hosts

• Monoxenous parasites are always viruses, heteroxenous are bacteria

• Heteroxenous life cycles do not require a host

• Monoxenous life cycles are more dangerous to humans

Open Ended

Why is it important for clinicians to understand the life cycle and natural habitat of Dicrocoelium dendriticum when diagnosing rare human infections?

Multiple Choice

Which of the following statements about human dicrocoeliasis, as reported in the Saudi Arabia case study, is correct?

• All patients were over 14 years of age.

• Praziquantel was successful in treating all patients.

• 23% of the patients were under 14 years of age.

• No patients had disturbed liver functions.

Open Ended

Describe the life cycle of Euhaplorchis californiensis as depicted in the diagram.

Multiple Choice

Why is it important to discuss immunity in the context of parasitic infections?

• Because immunity has no effect on parasitic infections.

• Because immune responses are responsible for much of the pathology, and understanding them can help develop vaccines.

• Because immunity only affects bacterial infections.

• Because vaccines are not related to immunity.

Multiple Choice

Which of the following are major challenges in the prevention of parasitic diseases according to the slides?

• Development of effective vaccines

• Lack of public awareness

• Shortage of medical professionals

• Overuse of antibiotics

Open Ended

Summarize the key features of adjuvants in licensed vaccines and their importance as described in the review abstract.

Multiple Choice

Which of the following is NOT a main function of the immune system as shown in the diagram?

• Immunological recognition

• Immune effector functions

• Immunological memory

• Pathogen replication

Multiple Select

Which factors influence infection dynamics according to the diagram?

• Genetics

• Vaccines

• Climate change

• Nutrition

Open Ended

Explain how the balance between pathogen presence and immune response determines health versus disease.

Multiple Choice

Which of the following cell types is part of the innate immune system?

• B-cells

• T-cells

• Macrophages

• Antibodies

Open Ended

Reflecting on today's lesson, what questions do you still have about the factors that impact human health, particularly regarding water contamination?

Multiple Choice

How can the contamination of drinking water with feces impact human health?

• It can cause waterborne diseases such as cholera and dysentery.

• It improves the taste of water.

• It increases the nutritional value of water.

• It has no effect on human health.
