Scientists called this disease tobacco mosaic. At the end of the nineteenth century, biologist Dmitry Ivanovsky decided at all costs to find a bacterium that causes it. However, while filtering the juice of plants, he stumbled upon something never seen before. The filter, which could stop all known microbes, was powerless against the causative agent of the tobacco mosaic, and it continued to infect more and more new bushes. So, it was something much smaller than bacteria but much more dangerous!
That was how humanity first discovered a new enemy, viruses.
And even though we’ve already seen them under the microscope, these little death machines continue to kill us.
In this video, you’ll find out: how did humanity fight against viruses without even knowing what it was? Why don’t many scientists consider viruses to be alive? And most importantly: how can we win the war against viruses?
