It will not kill their hosts because host organisms are capable of surviving on its own and provides energy source to the parasite. Generally, if the host cell dies then the parasite will also die. Hence, the parasite will not kill the host cells.

Do parasites die when the host dies?

Most parasites are obligate parasites and die when the host dies. “The best parasite harms the host the least.” The more recent the adaptation to parasitism of a host is more harmful. So parasites evolve to live, reproduce, and not kill the host.

What are the effects of parasites on the host?

Parasites may influence their hosts in different ways. They may cause the death of the host due to a direct lethal effect or an indirect effect. Direct lethal effects may occur if killing is a part of the life cycle of the parasite or if hosts and parasites have not developed an equilibrium.
