Viruses and Influenza

Introduction

  • Definition of viruses

  • Definition of influenza

  • Importance of understanding viruses and influenza

Types of Viruses

  • DNA viruses

  • RNA viruses

  • Retroviruses

DNA viruses are like tiny machines that invade our cells and use our own machinery to make copies of themselves. They have a genetic code made of DNA, just like we do. Examples of DNA viruses include herpes and chickenpox.

RNA viruses are similar to DNA viruses, but their genetic code is made of RNA instead of DNA. They also invade our cells and use our machinery to make copies of themselves. Examples of RNA viruses include the flu and HIV.

Retroviruses are a special type of RNA virus that can actually insert their genetic code into our own DNA. This means that once we are infected with a retrovirus, it becomes a permanent part of our genetic code. HIV is an example of a retrovirus.

Emerging viruses are viruses that are new or have recently started infecting humans. They can be very dangerous because our bodies have not had a chance to build up immunity to them yet. Examples of emerging viruses include Ebola and Zika. Scientists are always studying these viruses to try to find ways to prevent and treat them.

Emerging viruses

Structure of Viruses

  • Capsid

  • Envelope

  • Genome

    The capsid is like a shell that protects the virus's genetic material, which is called the genome. The genome is like a set of instructions that tells the virus how to make more copies of itself.

    Some viruses also have an envelope, which is like a coat that covers the capsid. The envelope helps the virus enter and exit cells.

    When we talk about capsid, envelope, and genome, we are talking about the three main parts of a virus: the protective shell (capsid), the coat (envelope), and the genetic material (genome).

Replication of Viruses

  • Attachment

  • Entry

  • Replication

  • Assembly

  • Release
