Viruses are a particularly fearsome “germ.” Though viral infections may resemble bacterial infections, antibiotics are useless against viruses. There are very few dedicated antivirals to kill them off. But who even knows if ‘kill’ is the right word to use for something that stretches the definition of ‘alive’? Viruses: they’re like microscopically tiny zombie-robots, hijacking cells and turning them into factories for themselves. But humanity can exploit viruses’ supremely odd workings and sneaky ways for their own purposes.
