Passive viruses that cause the skin disease during space travel are re-activated in the body. This has been revealed in the study of astronauts in International Space Station (ISS). After this, human missions sent to Mars and other planets in the future may be in danger. American Space Agency NASA said that the speed of activation of the virus depends on the period of space travel. The longer the space travel, the virus will be as active as possible.
The biggest problem facing Cosmic Radiation
Satish K Mehta, a scientist from NASA's Johnson Space Center, said, "Astronauts face microbiology (decreasing gravity) and cosmic radiation for several weeks and months. During their mission, their sleep and waking cycle worsens. Due to being cut off from people, they have a problem of stress. "To explore the same effect on the body during the space travel, the researchers gathered samples of astigmatics, blood and urine. During the journey and before and after the samples collected in the study, it came to light that during the journey of space, the hormone responsible for stress in the body starts to be known. This makes the body's immune system weak.
Passive viruses are also activated
Many times immune cells of the astronauts remain ineffective for 60 days after returning from space. Due to weakening of cells, passive viruses are also active. Giving details of the study, Mehta said, "47 out of 89 going from the Space Shuttle, but in ISS, for long periods of 23, in 14 astronauts, skin diseases begin to grow rapidly. The speed of these viruses increases during pilgrimages before and after the pilgrimage. "In some people, the symptoms of active these viruses are visible. Scientists say that it can be a major crisis on astronauts' health. It is necessary to solve this problem before sending humans to the Moon and Mars mission.
Four of the eight pandemic viruses found
In the investigation of saliva and urine, scientists found that four out of eight out of eight related skin diseases were activated during space travel. They include VZV, CMV and EBV with HSV responsible for smallpox and mouth ulcers. There may be problems related to fever, sore throat and dizziness due to CMV and EBV virus responsible for mono or kissing disease.
