NASA finds that Dormant Viruses Act during Eye Space



Space travel can be exciting for those watching far from home but there are many complicated difficulties as they approach new conditions that have never happened on Earth. NASA's new research is now revealing that there can be a dormant virus reactivation space.

Virus says half the teams on Space Shuttle missions and the International Space Station (ISS).

"NASA astronauts survive weeks or even months of exposure to microchipy and cosmic radiation – not to mention the G forces of resignation and re-entry.," Said the senior author, Dr. Thomas. Satish K. Mehta from KBR Wyle at the Johnson Space Center.

"This physical challenge is exacerbated by more common stresses such as social separation, childbirth and cycle after sleep has changed."

Mehta and his colleagues monitor the physiological impact of space light through saliva samples, analyze blood and urine from the astronauts. There was a problem with what they found.

"During the light of the space there is an increase in the secretion of stress hormones such as cortisol and adrenaline, which are associated with the immune system. Normally, prevention and elimination of viruses ̵

These circumstances could be made worse by the stressful environment the astronauts relate to.

"To date, 47 of the 89 (53%) astronauts on short space space flights, and 14 out of 23 (61%) on ISS missions reported longer their viruses or urine samples," Mehta said.

"These frequencies – along with the amount – of viral shedding are significantly higher than in samples from before or after flight, or from matched healthy controls."

Researchers felt four of the eight viruses human herpes including oral herpes and genital herpes ([HS9013] Fortunately, asymptomatic is the majority of viral leakage now. ”Only six astronauts developed any symptoms due to viral reactivation,” Mehta says, however, that the virus tsedding continues after flight, which could be a danger to immune or uninterrupted people on the Earth.

"Scanning VZV and CMV infection in fluids up to 30 days after returning from the International Space Station, "said Mehta.

In addition, as we go on longer missions to space,

"The size, frequency and duration of the viral transmission increases the length of space space."

Required countermeasures

Mehta argues that countermeasures need to be developed against this tsedding. Ideally, vaccination would only work for a while there is only one type of herpes;

"Other herpes virus trials have few pledges, so our current focus is on the development of targeted treatment regimes for individuals with viral reactor effects."

"This research is of great clinical importance to patients in the world Already, our technologies are developed by space space to make rapid viral sensitivity in saliva employed in clinics and hospitals around the world. , "concluded Mehta
