The video explains the presence of the deformed wing virus in bees, which is generally benign, affecting about 10% of the population. However, the introduction of the varroa mite changes this dynamic. The mite feeds on the bees' blood, leading to the disappearance of innocuous viruses and the proliferation of a lethal strain of the deformed wing virus. As a result, the frequency of the virus in bee colonies increases dramatically from 10% to 100%.
