Yes, it is true that many dangerous diseases can be transmitted through direct or indirect contact. But, while germs may harm the body, sin and sinfulness definitely harm the soul; making us unclean, defiled, before a pure and holy God.,, just as accumulated germs will eventually make our bodies sick, an accumulation of 'sin germs' will eventually make our souls, hearts and minds sin-sick too. We MUST wash them away regularly with God's Word!
