New research finds the risk of catching Ebola from a survivor to be ‘very low.’Researchers set out to discover how long the Ebola virus persists in different human body fluids — including blood, urine, semen, sweat, breast milk, feces, and vaginal fluids.While other health complications have been widely reported, the team did not find any evidence that the virus can reactivate to the point it becomes infectious for others by non-sexual contact.
