| human papilloma virus | <virology> A disease caused by the human papilloma virus characterised by a soft wart-like growth on the genitalia (for example penis, vulva). In adults this infection is most commonly transmitted sexually. Genital warts are very common and are increasing in incidence. Safe sex practices, such as using condoms can help decrease the risk of infection. Treatment includes several topical agents to eradicate the lesions, cryosurgery, laser therapy, electrocauterisation or surgical removal. See: alternate name condyloma acuminata. Acronym: HPV (27 Sep 1997) |

| human T-cell leukaemia virus | <virology> One of a group of retroviruses which causes the disease T-cell leukaemia in humans. T-cell leukaemia is a type of the cancer leukaemia where the body uncontrollably produces large amounts of abnormal (nonworking) T lymphocytes. (09 Oct 1997) |
| human T-cell lymphoma/leukaemia virus | A group of viruses (subfamily Oncovirinae, family Retroviridae) that are lymphotropic with a selective affinity for the helper/inducer cell subset of T lymphocytes and that are associated with adult T-cell leukaemia and lymphoma. Synonym: human T-cell lymphotropic virus. (05 Mar 2000) |
| human T-cell lymphotropic virus | A group of viruses (subfamily Oncovirinae, family Retroviridae) that are lymphotropic with a selective affinity for the helper/inducer cell subset of T lymphocytes and that are associated with adult T-cell leukaemia and lymphoma. Synonym: human T-cell lymphotropic virus. (05 Mar 2000) |
| human T lymphotrophic virus | A virus that has a predilection for human lymphoid cells. (05 Mar 2000) |
| human t-lymphotropic virus | <virology> Type i: A human, single-stranded RNA retrovirus from the subfamily Oncovirinae which causes adult T-cell leukaemia and T-cell lymphoma and may also be involved in certain demyelinating diseases (diseases where the protective myelin sheath around nerve fibres are destroyed). HTLV-I is closely related to HTLV-II (60% of their genomes are identical). Type II: A human, single-stranded RNA retrovirus from the subfamily Oncovirinae which may cause diseases such as T-cell leukaemia and T-cell lymphoma (but this has not been proven). HTLV-II is closely related to HTLV I (60% of their genomes are identical). Type III: An obsolete term for human immunodeficiency virus (HIV), which causes Acquired Immunity Deficiency Syndrome (AIDS). Acronym: HTLV (09 Oct 1997) |
| influenza a virus, human | Strains of influenza a virus causing influenza and sometimes pneumonia in humans. Transmission is by aerosol. (12 Dec 1998) |
| enteric cytopathogenic human orphan virus | eCHO virus |
| bovine herpes mammillitis | An ulcerative disease of the skin of the bovine teat caused by bovine herpesvirus type 2. Synonym: bovine ulcerative mammillitis. (05 Mar 2000) |
| genital herpes | <gynaecology, virology> A sexually transmitted infection caused by a herpes virus that results in the episodic outbreak of a painful vesicular skin eruption on the genitalia. The incubation period is approximately 6 days from the time of exposure. Other symptoms include fever, headache, muscle aches (27 Sep 1997) |
| herpes | <dermatology> Any inflammatory skin disease caused by a herpes virus and characterised by the formation of clusters of small vesicles. When used alone, the term may refer to herpes simplex or to herpes zoster. Origin: L., Gr. Herpes = a spreading cutaneous eruption, from herpein = to creep (18 Nov 1997) |
| herpes B encephalomyelitis | A frequently lethal disease of humans caused by infection with a normally latent monkey herpesvirus. (05 Mar 2000) |
| herpes catarrhalis | <virology> The Herpes simplex virus is responsible for several different infections in humans: gingivostomatitis (in children), pharyngitis, oral and lip lesions (recurrent Herpes simplex type 1), proctitis, (type 2) and genital herpes (type 2). (27 Sep 1997) |
| herpes circinatus bullosus | <dermatology> A chronic disease of the skin characterised by severe itching, extensive eruption of vesicles (blisters) and papules which occur in groups. May be associated with an occult malignancy in the elderly patient. Treatment includes sulpha-based antibiotics. In some cases this condition may be associated with malabsorption. Relapses are common. (27 Sep 1997) |
| herpes corneae | <ophthalmology, pathology> Inflammation of the cornea (and conjunctiva) due to herpes virus type I, a characteristic finding on physical examination of the eye (cornea) is a dendritic pattern (crystalline or tree-like pattern). (27 Sep 1997) |
