Introduction to Virology: How Viruses Work Learn more

?What is Virology?
Virology is a branch of science that deals with the study of viruses. Viruses are submicroscopic, parasitic particles of genetic material enclosed in a protein covering. The subject focuses on a number of aspects of these microorganisms, including their structure, classification and evolution, the diseases they cause, their interaction with the physiology and immunity of host and the techniques to segregate and culture them as well as their use in research and therapy. Virology is considered to be a subfield of microbiology or of medicine.
Who should take this course?
This course has been designed for students who are currently enrolled in a university to pursue advanced studies in virology. Even if you are not enrolled for an advanced course in virology, you should have molecularly-oriented introductory biology background.
What are the benefits of this course?
This introductory course in virology focuses on common reactions necessary for successful reproduction of viruses within a host cell and for their survival and spread within a host organism. In this course you will study the molecular basis of alternative reproductive cycles with examples taken from a set of viruses that infect human beings and animals.
