Mopping regularly with wood floor cleaner has no real impact on the living bacterium that causes sneezing and other flu symptoms. The only way to stop flu is to use common sense and good hygiene by washing your hands regularly and cleaning up objects that other people could touch. The virus lives in the mucus of the nose, throat, and eyes of the people who are infected. You can get the flu by touching objects or surfaces that have the virus on it and then touching your nose, eye, or mouth. But you can not get the flu if you touch someone who is infected. The virus travels between people on the tiny water droplets from coughs and sneezes. So, you can not get the flu from walking on a wood floor, table, or chair.
