Understand what happens to animals when they are affected by viruses

In this free online course, you will learn about animal viruses that affect pets, birds, sheep, cattle, swine and horses, and produce important diseases. These animal diseases may cause huge economic losses to farmers and severe emotional distress to animal owners. They may even be transmitted to humans, posing important questions about their spread and control. The course has been developed by a team at Complutense University of Madrid, who are all experienced in teaching virology and infectious diseases at veterinary schools at Madrid and Alfort.

Skip to 0 minutes and 12 seconds The term “virus” was invented in the 19th century to describe the mysterious cause of certain diseases, and since then, it has become synonymous with “problems”.

Skip to 0 minutes and 25 seconds When we consider the word virus, we think about Epidemic, Disease, and even an infection in our computers… We have even coined the term “viral” to refer to something that expands rapidly. But do we really know how viruses work and cause disease in the animals they infect?

Skip to 0 minutes and 49 seconds In this course, we will study many viral diseases that affect animals. Some, such as rabies, have been known since ancient times; others, such as West Nile fever, Ebola haemorrhagic fever, or the avian flu, have emerged with force in recent decades. Both ancient and recent viral diseases can cause major economic losses of milk, meat or egg production; some induce the death of our animals either, directly or by the need to euthanize them to prevent that the infection spreads; and undoubtedly, many of us know how sad it is to see our pets sick.

Skip to 1 minute and 39 seconds It is very difficult to cure a viral infection since, usually, there are no effective treatments against viruses. The truth is that viruses resemble the components of the cells they infect. This makes it very difficult to stop viral infections once they infect the cell. Therefore, it is very important to prevent that animals become infected, mainly avoiding the transmission between them. In this course, we will focus on the main mechanisms of transmission of viral diseases, learning step-by-step the different forms in which various types of viruses spread, and we will show related biological and medical aspects.

Skip to 2 minutes and 17 seconds We will also learn about some infections which are difficult to control as the virus establishes persistent infections, remaining hidden inside the cells, waiting to activate at the adequate time. In our tour, we will stop to know more about some of the most important viral diseases in animals and learn about their possible impact in the health of people.

Skip to 2 minutes and 49 seconds Accompany us in this course and you will have a very broad, cursory view of the importance of the diseases caused by viruses in animals. You will understand the reasons for their great expansion, and you will learn about the best methods and techniques available in our globalized world to prevent them and control them. Get ready to enter the world of viruses and the diseases that they cause as presented to you by a group of specialists in Virology, from the Schools of Veterinary Medicine and of Biology of the University Complutense of Madrid and of the University of Maisons-Alfort.

What topics will you cover?

  • Introduction to animal viruses, their form and structure (or morphology), and characteristics. Basic information to help understanding viral diseases in animals and humans.
  • Faecal-oral transmission: using parvoviruses and canine parvovirosis as an example.
  • Open wounds: focusing on rabies and other zoonotic viruses, which produce diseases in both humans and animals.
  • Arthropod transmission: viruses that are carried by insects and ticks, and introduced directly into the bloodstream.
  • Airborne transmission: such as influenza, which may be transmitted from birds and pigs to humans.
  • Other infections difficult to control because they are persistent: produced by viruses that remain in their host, including herpesvirus and retrovirus.

Learning on this course

On every step of the course you can meet other learners, share your ideas and join in with active discussions in the comments.

What will you achieve?

By the end of the course, you‘ll be able to...

  • Describe the differences between DNA and RNA viruses, naked and enveloped viruses, and how this affects variability of the genome and the resistance pattern to physical and chemical agents.
  • Compare the transmission requirements for the different ways viruses spread: airborne, through the skin (vertebrate/invertebrate/vector bites) shed in faeces, and how to avoid spread through management, such as quarantine, disinfection, etc.
  • Describe the epidemiology and the transmission routes of the diseases dealt with in the course and identify which are transmissible to humans (zoonosis).
  • Reflect on the pathogenesis of the different diseases, i.e., how viruses produce each specific disease, and the main clinical signs of the diseases mentioned above.
  • Reflect on the effects of climate change on the distribution of vectors of viral diseases and, thus, on the spread of arboviral diseases.
  • Evaluate which samples and techniques are the most conclusive to diagnose the different viral diseases mentioned above.
  • Identify which vaccines are used for the different viral diseases mentioned, their types, and problems that may arise from their use.

Who is the course for?

This course is designed for anyone with a keen interest in the science behind animal viruses and animal diseases. It will be particularly useful to veterinary and science students wishing to complement their studies and anyone working in animal health and welfare. A basic knowledge of biology is desirable, although not required. Though some aspects may be basic for specialists, such as veterinarians, the course will certainly complement their previous knowledge.

What software or tools do you need?

No specific hardware or other resources is required. A few steps will require padlet, which is freely available online.

Please note that the videos for this course are delivered in Spanish, with English subtitles and transcripts.
