Latent Varicella–Zoster Viral DNA in Human Trigeminal and Thoracic Ganglia

Abstract
Some human herpesviruses become latent in dorsal-root ganglia. Primary infection with the Varicella Zoster virus causes chickenpox, followed by latency, and subsequent reactivation leading to shingles (zoster), but the frequency and distribution of latent virus have not been established.
