Q

How do CMV become reactivated

A

Mechanism of reactivation

  1. primary infection
  2. Virus maintain latency
  3. During an inflammation or immune deficiency a lot of chemokine and cytokines are produced
  4. resulting in monocyte recruitment to the site of importance and they differentiate into Macrophages
  5. The virus uses the active Macrophage machinery to replicate itself

Normal people have memory cells that can deal with the reactivation, this is not the case for immunosuppressant people that get really sick
