Chickenpox is caused by the varicella-zoster virus (VZV).
Understanding the Varicella-Zoster Virus (VZV)
The varicella-zoster virus (VZV) is a highly contagious virus responsible for chickenpox. According to available information, chickenpox primarily spreads from unvaccinated individuals who have the virus to those who have never been infected. Alarmingly, nearly 90% of non-immune individuals in close proximity to someone with chickenpox will contract the infection.
Transmission of Chickenpox
Here's a breakdown of how chickenpox spreads:
- Primary Cause: The varicella-zoster virus (VZV).
- Main Mode of Transmission: Person-to-person contact, especially from unvaccinated individuals who are currently infected.
- High Contagion Rate: Approximately 90% of non-immune individuals exposed to an infected person will contract the disease.
