Chicken Pox

Chicken Pox a disease that is caused by the beginning infection of the varicella zoster virus


  • Itchy rashes on the skin
  • Fatigue
  • Fever
  • Loss of appetite
  • Headaches
  • Sore throat
  • Swollen lymph nodes

Immune cells involved in immune response

The antibodies are made by B cells and T cells are the natural killers. T cells are needed for recovery from varicella and this is why the infection produces a specific T cell-mediated immunity and a specific antibody to kill the virus.

How Varicella Replicates


1) The virus attaches to the host cell and injects DNA

2) Viral DNA circularizes

3) Viral DNA integrates into host cell chromosomes

4) The host cell reproduces normally, copying the integrated viral DNA and transmitting it to daughter cells

5) Many cell divisions produce many infected cells

6) When triggered, viral DNA exits the host cell chromosomes and starts the lytic cycle


1) The virus attaches to host cell and injects DNA

2) Viral DNA circularizes

3) New Viral DNA and proteins are synthesized and assembled

4) Cell bursts, which then releases the virus

Varicella goes though both the lysogenic and lytic cycle


Analgesic is used to relieve pain, antihistamine is used to stop allergic reactions, and an antiviral drug used to reduce the viruses ability to replicate.


A vaccine can be used to prevent this virus by preparing your immune system to recognize the disease.

Chickenpox is caused by the varicella zoster virus. This virus can spread easily, usually by touching or breathing in the virus particles
