Varicella+Zoster+Virus+(Shingles)

*Title is wrong & I can't change it!! :(

Historical background
In the late 18th century, William Heberden discovered how to differentiate between shingles and smallpox (Weller, 2000). In the beginning of the 20th century, it was observed that chickenpox and herpes zoster were caused by the same virus. This was eventually proven by Thomas Huckle Weller in 1953 (Weller, 1953).
