If inhaled an hour, the amount of virus is sufficient to trigger infection.
According to a recent report published in the Journal of the Royal Society Interface, a single sneeze could contaminate a room for a period of more than one hour.
Researchers from Virginia Tech, the United States to analyze air samples from three pieces of the aircraft, the waiting room at a health clinic, and three treatment rooms. As a result, half of the air samples obtained contain contaminated air particles flu virus.
"From an average, one cubic meter of air sampled was recorded containing more than 16 thousand flu virus particles," said Linsey Marr, head of the team of researchers from Virginia Tech, as quoted from MedIndia, Monday, February 7, 2011.
The virus, according to Marr, is still active in the air although it has more than one hour out of the respiratory tract of patients with flu sneezes.
Marr says, considering the high concentration of virus in the air, if a person continues to breathe the air in the room for an hour, the amount of virus is sufficient to trigger infection.
"air containing the virus particles are small enough to allow even the smallest of particles can survive for several days," said Marr. (art)
