The virus probably survives on an object at least as long as the object remains moist. More than 90% of people get infected by EBV in their lives. EBV is now proved linked to a bunch of chronic diseases and cancers, but there's no reported evidence that EBV leading to Fibromyalgia. However, a lot of people with Fibromyalgia have symptoms of EBV infection, it's possibly because people with Fibromyalgia have weak immune so the virus can be reactivated. You may talk to your primary doctor how to manage the Fibro pain, also discuss how to improve the immune.
