A Norovirus can be considered as a 30 nm in diameter spherical particle, made of protein and DNA·The Noroviruses are known to be
highly infective. As few as 10 viruses are enough to cause infection in a human. a) Suppose that an infected individual releases 5 cm3 of fluid containing 10% of Noroviruses by volume. Calculate the number of Noroviruses in this sample and the number of humans that could be infected with these viruses. What percentage of the human population on Earth (assumed 7 billion) could be infected? b) Could the virus spread around and infect all these humans only by diffusion? Calculate the diffusion coefficient and the time needed for one virus to diffuse to a length of 1 meter at 20°C (viscosity of water being 1.0x103 kg m s)?
I would say that because Jupiter already has a lot of mass on it and I would suspect that you would too. But I am not sure if it is 100% right, so correct me if I am wrong! Have a nice day! :)
