Sigh—the sweetest two-month vacation just whizzed by like a bullet, and school is back in session, with all the excitement and exhilaration of new beginnings. And guess what else? Flu season is on its way!
Some might have heard that one student with the flu could infect an entire classroom of children. While this sounds scary, it appears to be true. According to the New York State Department of Health, students within three feet of the infected student can “easily be infected” by inhaling airborne droplets. How is that possible? How fast do the droplets travel and how wide do they spread over the class?
We decided to test the flu virus spread with our tool of choice, computational fluid dynamics (CFD) simulation
Virus Distribution at around head height (between 0.9m and 1.5m)
Students exposed to viruses
Using scSTREAM to simulate classroom air flow and virus diffusion shows that more than half of the students in the classroom will be exposed to viruses from a student seated in the middle of the room. Students who do not feel well should be strongly encouraged to stay home untill they feel better
