Given that malaria appears to be more of a lifelong, chronic disease, the virus theory lends itself nicely; a virus could be both acute and/or chronic, whereas the unicellular parasite is identified with acute symptomology, rather than chronic, or recurrent symptoms. Many viruses, whose genetic information is not integrated into the host DNA, may lie dormant in tissues for long periods of time without causing much, if any, tissue damage. Viral infection does not always result in cell death or tissue injury; in fact, most viruses lie dormant in tissue without ever causing pathological effects, or they do so only under other provocations, such as trauma, another infection, emotional stress, menstruation, various illnesses and environmental factors. Plant RNA viruses must rely on insects with a proboscis to get them into a host cell; they do not ordinarily multiply in the insect but simply reside on its proboscis.
