It is highly recommended to have adequate knowledge of mathematics.

The Epidemiology and Statistics course is of the second year and is a compulsory subject of the degree of Veterinary studies. The subject introduces in the bases of the application of the statistics to the veterinary sciences and in the basic concepts of epidemiology that allow to understand the evolution of the diseases in the populations.

The objective of the subject is that the student knows the terminology and the methods used in statistics and in epidemiology.

The specific objectives are that the student knows:

- What are the basic statistical tests and in what situations can they be used.

- Apply the basic statistical tests and interpret the numerical results.

- Know the behavior of diseases and infections in animal populations.

- Design and carry out simple epidemiological studies.

- Apply the most appropriate study and epidemiological methods in each case.

- Develop the analytical and critical capabilities of an epidemiological study.

- Analyse, synthesise and resolve problems and make decisions.
- Apply scientific method to professional practice, including medicine
- Apply the basics governing the transmission and maintenance of diseases in animal populations.
- Assess and undertake epidemiological studies and therapeutic and preventive programs in accordance with the standards of animal welfare, animal health and public health.
- Demonstrate knowledge and use of statistical concepts and methods applicable to veterinary science.
- Diagnose different individual and collective animal diseases, and know about prevention measures, with emphasis on zoonoses and notifiable disease.
- Value and interpret the production and health parameters of one animal group, considering the economic and welfare aspects.

- Analyse, synthesise and resolve problems and make decisions.
- Apply appropriate statistical methods to different types of epidemiological studies.
- Apply concepts related with the transmission and maintenance of diseases in populations to the analysis of real-life situations.
- Apply scientific method to professional practice, including medicine
- Apply the concepts of statistics and epidemiology to the analysis of production and health parameters.
- Calculate and interpret measures of position and dispersion applicable to a data series.
- Define the epidemiological and statistical bases of evidence-based medicine.
- Describe the basic foundations of disease prevention programs.
- Design and perform simple epidemiological studies, selecting the most suitable for each case.
- Develop the capacity for critical appraisal of epidemiological studies.
- Distinguish the different types of epidemiological studies and their utility.
- Explain the evolution of diseases in populations and the factors that determine the same.
- Identify the pathways and methods for transmitting diseases.
- Properly evaluate the efficiency of a diagnostic test in terms of its application to a population.
- Recognise and describe basic causality and causal inference, and their relationship with statistics.
- Recognise the statistical distributions of a variable.
- Select, apply and interpret the most commonly used parametric and non-parametric statistical methods in veterinary science.

**Master classes - in non-contact format**

Economics of the disease

**Tutorials - in non-contact format**

There will be non-contact tutorials to resolve doubts about the different topics

Computer practices - non-contact:

Hypothesis and ANOVA tests

Ji-square test and regression

**Computer practices - face-to-face (if the health situation allows it):**

Introduction to the program R. Estad. description

Analysis and interpretation of data in the context of an epidemiological study

**Classroom debate - face-to-face (if the health situation allows it):**

Statistical problems

Problems with diagnostic methods and rates

Design of epidemiological studies

Analysis and interpretation of data in the context of an epidemiological study

*Unless the requirementsenforced by the health authorities demand a prioritization or reduction of these contents.

The teaching methodology will involve asynchronous theory classes and synchronous tutorials via Teams to resolve doubts that we will try to be as participatory as possible. We will also do synchronous computer practices via Teams in which students will have to obtain the statistical and epidemiological parameters of different databases.

We will also do synchronous practical classes in which students will have to obtain the statistical and epidemiological parameters of different databases.

At the same time, students will have to prepare some problems that will later be discussed in class and any doubts that may arise will be solved and they will have to prepare two oral presentations that will be discussed in the classroom.

*The proposed teaching methodology may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.”

Attendance at practical classes (face-to-face or synchronous) is mandatory to pass the subject.

The final grade is calculated based on:

- Statistical exam (30% of the note). The exam will be of short questions and problems.

- Epidemiology exam (40% of the note). The exam will be of test and short questions.

- 3 exercises (30% of the note).

. Assistance and deliveries of the statistical practices (5% of the note)

. Oral presentation on design of epidemiological studies (10% of the note)

. Oral presentation on analysis and interpretation of data in the context of an epidemiological study (15% of the note)

To approve, you need to take a minimum of 5 of each one of the exams. The last week the exam and the two analysis works of a database can be retrieved. If you have to go to recovery, the student must be examined of the part that is below 5. Students who have approved and want to raise their note should keep in mind that only the final exam will be considered.

*Student’s assessment may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.
