The project. Diagnostic tests for Sars-CoV-2
In light of the recent emergence of the Sars-CoV-2 worldwide, accurate and novel detection methods for the diagnosis of the disease are mandatory.
The objective of this subject is that at the end of the lectures you will be able to describe four different approaches for the diagnosis of the virus in different settings in the developed or in the developing world. This four approaches will be described in a written project which will be used for your assessment:

Approach 1. An approach for separating and preconcentrating SARS-CoV-2 virus from complex samples for further isolation of the virus.

Approach 2. An RDT for the detection of the infection in low resource settings to screen out patients with requires strict surveillance and quarantine.

Approach 3. A test for quantifying the immunological response of the patients.

Approach 4. A confirmatory diagnosis of COVID in an outbreak setting and assessment of patient viral load as a predictor of outcome.
Instructions for the COVID Project
The main objective is to learn different methods based on Biomolecules (mainly antibodies and DNA based methods) by applying them in the detection of a target. The target selected is the SARS-CoV-2. Virus. Four different analytical challenges will be addressed, as described above. All these approaches will be discussed in the final project. The project will be developed step by step by meeting different milestones, and the lectures will help you out to achieve these milestones.
Introductory lesson of different approaches to detect communicable diseases
In this lesson you will find the different approaches in order to obtain a final diagnosis in the case of any infection disease, taking as a model SARS-CoV-2 virus. The link will be activated soon
Milestone 1
Find general information about SARS-CoV-2 virus infection and diseases. Write a summary about the virus that will help you to build up the introduction for the project. It will be the DELIVERABLE 1.
Milestone 2
Find general information about the current diagnosis of the SARS-CoV-2 virus. It will be the DELIVERABLE 2.
Milestone 3. The final project
Describe the problem in an introduction (DELIVERABLE 1) as well as the current diagnostic of COVID (DELIVERABLE 2). Furthermore, describe, step by step, the development of each test procedure (approaches 1, 2, 3 and 4) and the protocol, for the detection of the biomarker related with SARS-CoV-2 Virus, taking into account:
- The production of the bioreagent (for instance, antibodies from the immunization to the purification) or, instead, the availability of commercial reagents.
- The format used for this specific biomarker as well as the platform.
- The solid support and the immobilization strategy for the bioreagent.
- The labelling of the bioreagent, if needed.
- The signal obtained for the quantification of the biomarker.
The theoretical lectures will help you out to fill all the final project, which will be the DELIVERABLE 3.
Assessment
The assessment of this part of the topic will be as follows,
i) Continuous assessment (40 % of the mark)
Virtual assessment activities proposed for the theoretical lectures as quizzes and as questions to solve in the forum.
QUIZ 1 QUIZ 2 QUIZ 3 QUIZ 4 QUIZ 5 QUIZ 6
The activities are designed to encourage the learning of specific skills. Activities must be delivered on time, on the specific place in a post open for that in the website. On the other hand, individual, autonomous work is required in order to reinforce the knowledge from reading and understanding the proposed reference books, web pages, tutorial videos or books that can be provided for specific topics. In order to carry out a self-assessment of learning, online multiple-choice tests will be proposed for each of the units, and their completion will also be considered in the assessment.
ii) The COVID Project (60 % of the marks)
The Covid Project, including the three milestones: DELIVERABLE 1 (10 %), DELIVERABLE 2 (10 %) and DELIVERABLE 3 (40 %), (the final project).
Example of the assessment
Your marks will appear on the dashboard, in the GradeBook, as shown below:
