Virus Life Cycle – Growth Curve

Taken from NYP's Lecture Virus Host Interaction Part 1 (for student).ppt

As you can see the virus growth curve is divided into 3 main parts. They are

  • Attachment
  • Eclipse period
  • Virus burst


At attachment stage, the virus that is in the blood stream will be attached to the host cells, thus beginning to decrease in numbers, therefore having a negative gradient.
At the eclipse stage, more and more virus already penetrated the host cell and is undergoing the replication process, and thus the virus titre decreases. It reaches a 0 gradient when virus in the external medium is no longer detected.The original virus count gets subtracted from the virus released to give the virus yield.
