A1 - Nussbaum, Jesse A1 - Schwartz, Brian PY - 2022 T2 - Review of Medical Microbiology & Immunology: A Guide to Clinical Infectious Diseases, 17e AB - Host defenses against viruses fall into two major categories: (1) nonspecific, of which the most important are interferons and natural killer (NK) cells and (2) specific, including both antibody and cell-mediated immunity. Interferons are an early, first-line defense, whereas humoral immunity and cell-mediated immunity are effective only later because it takes several days to induce the humoral and cell-mediated arms of the immune response.
