Can a pathology(I dont know if this is the correct term) kill an invading virus? I've been thinking about that amid this corona virus hysteria. My mother has miastenia gravis, a very rare disease, to make it brief, antibodies attack the host and external agents, instead of attacking only external agents, I've been thinking if there is a possibility of surviving the covid 19 thanks to the aggressive behavior of the immune system, killing every symptom or at least most? I am asking because the question appeared yesterday in my head but I found nothing in google about diseases killing other external agents. My mother rarely get a fever or any common flu, even with miastenia gravis.
