Fight against parasitosis

Objectives

After this unit, students should be able to:
1. To introduce concepts of control, elimination and eradication of parasitic diseases.
2. To characterize the basic components supporting control programs of parasitic diseases: i) treatment and prophylaxis; ii) vector and intermediate host/reservoir control; iii) community health education.
3. To develop skills in the application of currently available tools for control and monitoring of mosquito populations.
4. Addressing novel control strategies under experimental development: vaccines and genetically modified mosquitoes.
5. To identify the main obstacles to the success of control programs, particularly concerning implementation and sustainability.

Teaching method

Teaching of this course will be based on the lecturing method, translated into 7 theoretical lessons; the demonstrative method, with two laboratory practical classes; and a Seminar given by the students where the active and interrogative methods will be applied. There will also be tutorial sessions to support student’s autonomous study and seminar preparation.

Evaluation method

Student evaluation will be based on two elements: student performance in the seminar class (weighting factor: 0.6), and a theoretical written exam consisting of 20 multiple choice questions and a development question (weighting factor: 0.4). Approval to the course implies: i) a minimum class attendance of 75%; obtaining a final mark of 10 points (out of a maximum of 20 points).
