What is Epstein‐Barr virus infection after adolescence and Human herpesvirus 6A as risk factors for multiple sclerosis about?
## Background and purpose Infections with human herpesvirus 6A (HHV‐6A) and Epstein–Barr virus (EBV) have been linked to multiple sclerosis (MS) development. For EBV, late infection has been proposed as a risk factor, but serological support is lacking. The objective of this study was to investigate how age affects the EBV and HHV‐6A associated risks of developing MS. ## Methods In this nested case–control study, Swedish biobanks were accessed to find pre‐symptomatically collected blood samples from 670 individuals who later developed relapsing MS and 670 matched controls. A bead‐based multiplex assay was used to determine serological response against EBV and HHV‐6A. Conditional logistic regression was used to calculate odds ratios and 95% confidence intervals. ## Results Seropositivity against EBV exhibited a pattern where associations switched from a decreased risk of developing MS in the group below 20 years of age to an increased risk amongst individuals aged 20–29 and 30–39 years (__p__ for trend 0.020). The age of transition was estimated to be 18.8 years. In contrast, HHV‐6A was associated with increased MS risk in all age groups (total cohort odds ratio 2.1, 95% confidence
