NASA said astronauts traveling in space are returning home with herpes.
According to new research, half of people traveling outside the Earth's atmosphere aboard the space shuttle or the International Space Station suffer from "reactivation" of the herpes virus.
According to Metro, Dr. Satish K. "Space conditions are thought to be detrimental to the immune system while NASA astronauts experience weeks or even months of exposure to microgravity and cosmic radiation. – not to mention the maximum powers to take off and restitution ", and this physical challenge is compounded by more familiar pressures such as social separation incarceration, sleep cycle and change of awakening.
"During spaceflight, the secretion of stress hormones such as cortisone and adrenaline inhibit the immune system," he said. "We have noticed that the immune cells of astronauts, especially those that inhibit and eliminate viruses, become less effective during space travel and even 60 days later." The activation does not necessarily cause the formation of wounds or viruses to attack the human body again.
"Up to now, 47 astronauts on Space Shuttle flights out of 53 (53%) have been short-lived, and 14 out of 23 (61%) during long space station missions carry virus-borne viruses. Herpes in saliva or urine samples, "adding that" these frequencies, as well as the number of viruses excreted, are significantly higher than samples taken before or after the flight, or from identical health checks. "
Last year, scientists discovered a thriving ecosystem of "infectious organisms" aboard the International Space Station, where the NASA team discovered five different types of "bacilli", a bacterium species that follows the type of amphibians, which are similar to those of hospitals Where the latrines of the orbital base were one of the main sites of infection with the exercise area. According to the researchers, there is "a 79% chance that this could cause the disease", although the analysis was only done on samples that died at this stage, the risk is higher or lower after further research.
