What Is DRESS Syndrome?
3. Reactivation of Viruses
It is not uncommon for us to be infected by pathogens, only for those pathogens to become dormant in our bodies. This includes, but is not limited to, some relatively common pathogens such as the Epstein Barr virus (EBV), and the human herpesvirus 6 (HHV6).
When dormant, these pathogens will cause no symptoms at all, although they can still be contagious to other people. They can, however, be reactivated sometimes and this will cause symptoms to return. Some people can find that certain medications will reactivate otherwise dormant viruses, and this can cause them to become quite ill as a result.
