High School Is An Excellent Medium For Transmission Of Influenza Virus

High School Is An Excellent Medium For Transmission Of Influenza Virus.
By outfitting students and teachers with wireless sensors, researchers simulated how the flu might barbecue through a regular American cheerful school and found more than three-quarters of a million opportunities for infection daily. Over the dispatch of a single school day, students, teachers and staff came into buddy-buddy proximity of one another 762868 times - each a potential occasion to spread illness. The flu, match the common cold and whooping cough, spreads through tiny droplets that contain the virus, said protagonist study author Marcel Salathe, an assistant professor of biology at Pennsylvania State University.

The droplets, which can tarry airborne for about 10 feet, are spewed when someone infected coughs or sneezes, Salathe said. But it's not known how terminate you have to be to an infected soul to get the flu, or for how long, although just chatting briefly may be enough to pass the virus. When researchers ran computer simulations using the "contact network" text collected at the high school, their predictions for how many would fall unpleasantness closely matched absentee rates during the actual H1N1 flu pandemic in the fall of 2009.

And "We found that it's in very thorough agreement," Salathe said. "This data will allow us to foretell the spread of flu with even greater detail than before". The study is published in the Dec 13, 2010 online print run of the Proceedings of the National Academy of Sciences. Figuring out how and where an infectious virus will spread is highly complex, said Daniel Janies, an associate professor of biomedical informatics at Ohio State University in Columbus.

The genomics of the disease, or the genetic makeup of the pathogen, can motivate its proficiency to infect humans as can environmental factors, such as weather and whether a particular virus or bacteria thrives during a given season. Your genetic makeup and salubriousness also influence how susceptible you are to a particular pathogen, he said.
