Transmission of VZV

B) False

Answer: B

Few things are relatively less know about VZV infection. 

  •  Humans are the only known hosts of VZV infection
  • VZV is transmitted in humans by droplet and airborne routes

Exposure to airflow from rooms occupied by patients with VZV is one of the major risk factors transmission.
