To figure out the mass of a subatomic particle, then, you'd use Albert Einstein's famous equation E=mc^2 to get the mass (m) in kilograms. Perhaps one of the biggest misconceptions about viral spread is that for a mask to be effective, it must filter out all particles that are the size of a single virus. She wanted to understand why COVID19 transmission messaging had changed and what she should do to protect her family.

While the benefits of a specific mask will depend on the fabric and construction of the mask (not to mention how it is worn), having some form of barrier between an infected individual and a healthy individual is far superior to open air allowing for the transfer of virus between those individuals, Makal writes. Answer (1 of 37): Okay, so, until last week, I would never have imagined that anyone would seriously ask this question. Viruses contain around 4 million atoms and are, on average, one thousand times larger than oxygen and nitrogen molecules. An additional filter or piece of material can be put in there to strengthen the mask. 2012 proteinaceous: of, pertaining to, or consisting of protein.
