As mentioned previously, after a primary VZV infection, the virus will remain dormant in the sensory ganglia of its host. When reactivated, VZV will erupt from the sensory neurons and infect surrounding skin tissue, causing characteristic rashes and severe pain due to nerve damage. Therefore, identifying the VZV factors responsible for not only skin-tropism, but also neurotropism is of great importance.
