A typical virus is a packet of protein and DNA (or RNA) and can be spherical in shape. The influenza A virus is a spherical virus that has a diameter of 85 nm. If the volume of saliva coughed onto you by your friend with the flu is 0.023 cm3 and 10−9 of that volume consists of viral particles, how many influenza viruses have just landed on you?
