Dangerous viruses become active during space travel


Passive viruses that cause 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 infection will be as active as possible. 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 the people around them, there is a problem of stress.

Researchers have collected samples of saliva, blood, and urine from the astronauts to find out the same effects on the body during space travel. During the journey, the study of samples collected before and after it came out that during space travel, the discharge of hormones responsible for stress in the body occurs. As a result, the body’s immune system becomes weak. Many times immune cells of the astronauts remain ineffective for 60 days after returning from space.

Due to the 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 skin diseases in the body of 14 of 23 astronauts who stay long in ISS begin to grow rapidly. The speed of these viruses increases during the journey before and after the journey. ‘

Some people show signs of active these viruses. Scientists say that this can cause a big 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 Slieve and Urine, scientists found that four out of eight related skin diseases were active during space travel. They include VZV, CMV, and EBV with HSV responsible for smallpox and mouth ulcers. Mono or kissing disease become infected with CMV and EBV infection. There may be problems like fever, throat disorders and dizziness in this disease.
