PATHOLOGY

Detailed explanation-1: -Usually, although parasites harm their hosts, it is in the parasite’s best interest not to kill the host, because it relies on the host’s body and body functions, such as digestion or blood circulation, to live.

Detailed explanation-2: -How Do Parasites Survive in their Hosts? Parasitism is a constant battle for survival between the parasite and its host. Because parasites depend on their host for food and shelter, they must not destroy the host until they are ready to move on to the next host. Meanwhile, the hosts must protect themselves from harm.
