NASA is conducting a war in orbit – against space herpes.
Astronauts aboard the International Space Station (ISS) and other missions have been plagued by a resurgence of the often dormant virus, according to astronauts study by NASA researchers published in the month's "Frontiers in Microbiology".
Approximately 53 percent of astronauts on short-range space shuttle flights have herpes signs, according to study lead investigator Satish Mehta.
Exposure Microgravity and cosmic radiation along with the power of blasting have affected the immune system of space travelers.
"During space travel, the secretion of stress hormones like cortisol and adrenaline, which are known to suppress the immune system, is increasing," said Satish, who researches at the Johnson Space Center.
"Accordingly, we find that the immune cells Astronauts ̵
This can be dangerous on longer space flight missions, such as waving, soaring! – to Mars, the researchers said.
A total of 47 out of 89 astronauts showed signs of the virus on short space shuttle missions and 14 out of 23 on long missions.
"These frequencies – as well as the amount – of virus delivery is significantly higher than pre-flight, post-flight or matched healthy controls," said Satish.
