Because their immune system's are not good.
black rats were hosts for Yersinia pestis bacterium. Fleas help to spread them to humans.

It is impossible to stop. Rats are hosts of Yersinia pestis bacterium. And you can't kill all the arts!
Parasites have highly developed systems for attaching to their hosts, evading the immune system, and extracting nutrients. They have specialized structures like hooks, suckers, or adhesive pads that facilitate attachment, allowing them to establish a long-term relationship with their host. Additionally, parasites have evolved complex mechanisms to manipulate host behavior and immune responses to ensure their survival and reproduction.
Tapeworms are the adult class of parasites and they are fond of living inside the intestine of their hosts. Tapeworms passively avoid the host defensive system by host digestive system due to the tapeworms coating that keeps on producing by itself and use it as its defense mechanism.
/etc/hosts Only root can change it, users can view it
If you delete the hosts file then you would get too many pop up's and your system would take longer time to display the webpages .
Viruses do not have the ability to evolve in the same way as living organisms with DNA. However, they can undergo genetic changes through mutations and recombination which can impact their ability to infect hosts and evade the immune system. This can lead to the emergence of new strains or variants of viruses.
It's called DNS
root partition
Mutations may result in a beneficial change. For example: An organism like a virus or bacteria relies on avoiding the immune cells of the body to be able to survive and live in a hosts body. If they mutate, then antibodies may not recognise them - allowing the organisms to avoid destruction by the immune system of the body for a short time, before new antibodies are produced by new plasma cells.
