| viral antigen | Those antigens specified by the viral genome (often coat proteins) that can be detected by a specific immunological response. Often of diagnostic importance. (18 Nov 1997) |

| viral gastroenteritis | <pathology> An inflammatory condition of the intestines that results from an infection with a virus. Rotavirus is a common cause. Abdominal pain, diarrhoea, nausea and vomiting are common symptoms. (27 Sep 1997) |
| viral haemagglutination | The nonimmune agglutination of suspended red blood cells by certain of a wide range of otherwise unrelated viruses, usually by the virion itself but in some instances by products of viral growth, the species of erythrocyte agglutinated differing with the different viruses. See: haemagglutination inhibition. (05 Mar 2000) |
| viral haemorrhagic fever | An epidemic viral illness seen in southern Sudan and Zaire, caused by the Ebola virus. The illness is characterised by fever, malaise, muscle aches, respiratory symptoms, diarrhoea, vomiting, epistaxis, haemoptysis, haematemesis, rash, tremors and subconjunctival haemorrhages. Transmitted by close bodily contact with infected individuals (blood, faeces and body fluids). Incubation is-21 days with initial symptoms of fever and headache. There is no specific treatment and death can occur within 10 days. (27 Sep 1997) |
