NEW YORK (Reuters Health) – Herpes viruses return to most astronauts' lives as they move through space, researchers say: one in 14 to 7% of the virus is already infected with the virus herpes in space.
The researchers found that 57% of the astronauts studied were studying the virus in more space than in the world, noting that viruses causing cold sores, shingles and glandular fever become dormant over time, but that periods of stress or exhaustion can reactivate them. .
Going into space weakens the immune system enough to allow the re-emergence of inactive viruses, which could pose a risk to the health of long-haul travelers, the researchers said.

The researchers, funded by NASA, have studied the saliva of astronauts looking for traces of HSV-1 virus, a strain of herpes that causes ulcers Cold, which can also affect the genitals and other parts of the body. body.
The results show that 53% of astronauts aboard the Space Shuttle and 61% of the International Space Station crew experience the effects of the spread of the virus by spreading and spreading, and the longer astronauts spend in space, the more the virus is active and the quantities discovered the larger.
The activation of the virus is due to an increase in the secretion of stress hormones such as cortisol and adrenaline during space travel, called immune system inhibition.
