I think the way the MC virus works is it's probably mostly infectious from the fully developed white bumps, which are probably filled with viruses. When those white bumps touch another person the viruses will start infecting the skin and then they seem to invisibly "dig" deeper, infecting cell to cell to the lower layers of skin first before they start to form a small bump after about a month and then it might take one or two months for most of the bumps to be visible as the fully developed white bumps.
But each place where the virus touches the skin will get a different "dose" amount of viruses and take a different amount of time for the viruses to form a bump. The time to develop is probably based on the "dose" of viruses in the area. The more firmly the white bump touched the skin, the faster the bump will develop in that area. Just from one touching event some bumps might start to develop after about a month and some might take several months to develop.
I think the body makes antibodies to the MC fairly quickly and I think the antibodies prevent too much self reinfection so I don't think the MC really "spreads" much on the same person as some people think, it's more you first see the bumps appear where the skin received a higher dose of viruses, and then lower dose areas take longer to develop.
