||Incidence of Epstein-Barr virus in astronaut saliva during spaceflight

||Astronauts experience psychological and physical stresses that may result in reactivation of latent viruses during spaceflight, potentially increasing the risk of disease among crewmembers. In order to test the hypothesis that the level of Epstein-Barr virus (EBV) in the saliva of astronauts increases during spaceflight, a total of 534 saliva specimens were collected from 11 EBV-seropositive astronauts before, during, and after four space shuttle missions. The presence of EBV DNA in saliva was assessed by polymerase chain reaction. The findings were that EBV DNA was detected more frequently before flight than during or after flight. No significant difference between the inflight and postflight periods was detected in the frequency of occurrence of EBV DNA. In conclusion, the increased frequency of shedding of EBV before flight suggests that stress levels may be greater before launch than during or after spaceflight.
