| influenza | An acute viral infection involving the respiratory tract, occurring in isolated cases, in epidemics or in pandemics striking many continents simultaneously or in sequence. It is marked by inflammation of the nasal mucosa, the pharynx and conjunctiva and by headache and severe, often generalised myalgia. Fever, chills and prostration are common. Involvement of the myocardium and of the central nervous system occur infrequently. A necrotising bronchitis and interstitial pneumonia are prominent features of severe influenza and account for the susceptibility of patients to secondary bacterial pneumonia due to Streptococcus pneumoniae, Haemophilus influenzae and Staphylococcus aureus. The incubation period is one to three days and the disease ordinarily lasts for three to ten days. Influenza is caused by a number of serologically distinct strains of virus, designated A (with many subgroups), B and C. Synonym: flu, grippe. (18 Nov 1997) |
|---|---|
| influenza a | A particular genus of influenza virus. Prone to genetic variability, the influenza vaccine must be updated annually. Symptoms of influenza include fever, muscle aches, headache, malaise, chills, cough and sore throat. (27 Sep 1997) |
| influenza B | Influenza caused by strains of influenza virus type B; outbreaks are usually more limited than those due to influenza virus type A, although infections by the two types are clinically indistinguishable; occasionally associated with Reye's syndrome. (05 Mar 2000) |
| influenza bacillus | <bacteria> Bacterium sometimes associated with influenza virus infections, causes pneumonia and meningitis. (18 Nov 1997) |
| influenza C | Influenza caused by strains of type C influenza virus; the disease is milder than that caused by types A and B and has become uncommon in recent years. (05 Mar 2000) |
| influenza meningitis | <pathology> A form of meningitis caused by the bacterium haemophilus influenza. Inflammation of the membranes (meninges) covering the brain and spinal cord can result after infection with this organism. Influenza meningitis occurs most frequently in children under 5 years old. Onset may be sudden or occur more slowly after an upper respiratory infection. Symptoms and features include fever, headache, stiff neck, photophobia and mental status changes. Infants may be irritable and exhibit poor feeding associated with fever. Severe cases may progress to seizures, coma and death. Treatment always includes high-dose systemic antibiotics and corticosteroids may also be used in some select cases. (27 Sep 1997) |
| influenza nostras | Influenza, usually of a less severe type, occurring with some degree of regularity during the winter season, especially in the larger cities of the world. Synonym: influenza nostras. (05 Mar 2000) |
| influenza type a | A common acute viral infection of the nasopharynx and respiratory tract which occurs in epidemic forms. A common cause is the Influenza a virus. Annual vaccination is recommended for those in high risk groups (health care workers, elderly and immunocompromised) for influenza infection. Common symptoms include runny nose, fever, weakness, headache, body aches, muscle aches, nausea and back pain. Treatment of symptoms has been successful with amantadine or rimantadine. (27 Sep 1997) |
| influenza vaccine | A special vaccine which provides immunity to infection by a variety of Influenza viruses. The vaccine is updated annually due to the constant introduction of new viral strains. Flu vaccination programs are common in the elderly population and any other groups who are at increased risk of viral infection. (27 Sep 1997) |
| influenza viruses | Virus's of the family Orthomyxoviridae which cause influenza and influenza-like infections of humans and other animals; virus's included are influenza virus types A and B of the genus Influenzavirus, causing, respectively, influenza A and B, and influenza virus type C, which probably belongs to a separate genus and causes influenza C. (05 Mar 2000) |
| endemic influenza | Influenza, usually of a less severe type, occurring with some degree of regularity during the winter season, especially in the larger cities of the world. Synonym: influenza nostras. (05 Mar 2000) |
| equine influenza | <veterinary, virology> A highly contagious upper respiratory infection of horses and other equids caused by equine strains of influenza virus type A. It is characterised by fever and respiratory signs similar to but more severe than those of equine rhinopneumonitis; oedema of the lower trunk and limbs (epizootic cellulitis) may occur; the disease is frequently fatal when secondary bacterial pneumonia intervenes. (05 Mar 2000) |
| bovine virus diarrhoea virus | A virus of the genus Pestivirus, in the family Togaviridae, causing bovine virus diarrhoea; New York, Oregon, and Indiana strains of the virus are recognised. Synonym: mucosal disease virus. (05 Mar 2000) |
| abelson leukaemia virus | A defective murine leukaemia virus capable of transforming lymphoid cells and producing a rapidly progressing lymphoid leukaemia after superinfection with friend, moloney, or rauscher virus. (12 Dec 1998) |
| Abelson murine leukaemia virus | A retrovirus belonging to the Type C retrovirus group subfamily (family Oncovirinae) which is associated with leukaemia and produces in vitro transformation of mouse cells. (05 Mar 2000) |
