Without a Varicella Zoster Virus Infection, no Schizophrenia

Abstract

Background:
Despite decades of research and major efforts, a cause or the cause of schizophrenia is still not
identified. Although many studies indicate that infectious agents are related to schizophrenia, no
definite consensus has been reached on this issue.
Methods:
The purpose of this study was to investigate the relationship between varicella zoster virus (VZS) and
schizophrenia, while relying on new statistical methods.
Results:
The meta-analysis results provide striking evidence that VZV is a necessary condition of
schizophrenia.
Conclusion:
There is some weak evidence that VZV infection is the cause of schizophrenia
