| viral transformation | <oncology, virology> Malignant transformation of an animal cell in culture, induced by a virus. (18 Nov 1997) |
| viral vaccines | Suspensions of attenuated or killed viruses administered for the prevention or treatment of infectious viral disease. (12 Dec 1998) |

| viral wart | A keratotic papilloma of the epidermis which occurs most frequently in young persons as a result of localised infection by human papilloma virus, usually types 2 and 4; the lesions are of variable duration, eventually undergoing spontaneous regression, and are both exophytic and endophytic, with hyperkeratosis, parakeratosis, hypergranulosis, koilocytosis, and papillomatosis. Synonym: common wart, infectious warts, verruca simplex, viral wart. (05 Mar 2000) |
| cell transformation, viral | An inheritable change in cells manifested by changes in cell division and growth and alterations in cell surface properties. It is induced by infection with a transforming virus. (12 Dec 1998) |
| meningitis, viral | Meningitis of viral origin usually due to picornaviruses, togaviruses, herpes viruses, paramyxoviruses, or arenaviruses. Symptoms include headache, malaise, nausea, fever, and neck stiffness. (12 Dec 1998) |
| RNA, viral | Ribonucleic acid that makes up the genetic material of viruses. (12 Dec 1998) |
| conjunctivitis, viral | Inflammation, often mild, of the conjunctiva caused by a variety of viral agents. Conjunctival involvement may be part of a systemic infection. (12 Dec 1998) |
| pneumonia, viral | Pneumonia caused by a virus. (12 Dec 1998) |
| haemagglutination, viral | Agglutination of erythrocytes by a virus. (12 Dec 1998) |
| haemorrhagic fevers, viral | A group of viral diseases of diverse aetiology but having many similar clinical characteristics; increased capillary permeability, leukopenia, and thrombocytopenia are common to all. Haemorrhagic fevers are characterised by sudden onset, fever, headache, generalised myalgia, backache, conjunctivitis, and severe prostration, followed by various haemorrhagic symptoms. Haemorrhagic fever with kidney involvement is haemorrhagic fever with renal syndrome. (12 Dec 1998) |
| cytopathogenic effect, viral | Visible morphologic changes in cells infected with viruses. It includes shutdown of cellular RNA and protein synthesis, cell fusion, release of lysosomal enzymes, changes in cell membrane permeability, diffuse changes in intracellular structures, presence of viral inclusion bodies, and chromosomal aberrations. It excludes malignant transformation, which is cell transformation, viral. Viral cytopathogenic effects provide a valuable method for identifying and classifying the infecting viruses.

| sexually transmitted diseases, viral | Viral diseases which are transmitted or propagated by sexual conduct. (12 Dec 1998) |
| skin diseases, viral | Skin diseases caused by viruses. (12 Dec 1998) |
