| endemic stability | A situation in which all factors influencing disease occurrence are relatively stable, resulting in little fluctuation in disease incidence over time; changes in one or more of these factors (e.g., reduction in proportion of individuals with immunity from exposure to infectious agent) can lead to an unstable situation in which major disease outbreaks occur. Synonym: enzootic stability. (05 Mar 2000) |

| endemic syphilis | Syphilis caused by organisms closely related to Treponema pallidum; spread by personal, but not necessarily venereal, contact; usually acquired in childhood, most common in areas of provery and overcrowding; rare in the United States; includes yaws, pinta and bejel. Synonym: endemic syphilis. (05 Mar 2000) |
| endemic typhus | Murine typhus, an acute infectious disease with fever, headache, and rash, all quite similar to, but milder than, epidemic typhus, caused by a related microoganism, Rickettsia typhi (mooseri), transmitted to humans by rat fleas (Xenopsylla cheopis). The animal reservoir includes rats, mice and other rodents. Murine typhus occurs sporadically worldwide but is more prevalent in congested rat-infested urban areas. Also known as rat-flea typhus or urban typhus of Malaya. (12 Dec 1998) |
| typhus, endemic | See Typhus, murine. (12 Dec 1998) |
| typhus, endemic flea-borne | An infectious disease clinically similar to epidemic louse-borne typhus (typhus, epidemic louse-borne), but caused by rickettsia typhi, which is transmitted from rat to man by the rat flea, xenopsylla cheopis. (12 Dec 1998) |
| Asian influenza | A worldwide influenza, apparently originating in China in the summer of 1957, which produces a milder disease than that of the pandemic of 1917-1919. (05 Mar 2000) |
| avian influenza | Infection of domestic and wild fowl and other birds with influenza a virus, avian. (12 Dec 1998) |
| avian influenza virus | <virology> A type A influenza virus (genus Influenzavirus) that causes fowl plague. Synonym: fowl plague virus. (05 Mar 2000) |
| vaccine, influenza | See Vaccine, flu. Vaccination, dtap: like dpt, dtap protects from diphtheria, pertussis (whooping cough) and tetanus. Dtap is the same as dtp, except that it contains only acellular pertussis vaccine which is thought to cause fewer of the minor reactions associated with immunization and is also probably less likely to cause the more severe reactions occasionally seen following pertussis vaccination. Dtap is currently recommended only for the shots given at 18 months and 4-6 years of age. Vaccination, dt: dt (diphtheria and tetanus) vaccine does not protect from pertussis and is usually reserved for individuals who have had a significant adverse reaction to a dpt shot or who have a personal or family history of a seizure disorder or brain disease. (12 Dec 1998) |
| Russian influenza | A pandemic of a strain influenza A virus thought to have originated in Russia; occurred in 1978. (05 Mar 2000) |
| haemagglutinin glycoproteins, influenza virus | Membrane glycoproteins from influenza viruses which are involved in haemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of ha glycoproteins and nine of na glycoproteins have been identified from influenza a virus; no subtypes have been identified for influenza b or influenza c viruses. (12 Dec 1998) |
| Haemophilus influenza | <bacteria> A gram-negative bacteria that is a common cause for epiglottitis, meningitis, conjunctivitis, sepsis and respiratory infections. Haemophilus influenza type b is a gram-negative bacteria that is responsible for a significant percentage of bacterial sepsis (blood-borne infection) cases in infants under 4 months of age (pneumonia, epiglottitis, sepsis, septic arthritis, cellulitis). There is a new vaccination available to protect against this common infant pathogen (HIB vaccine, haemophilus influenza b vaccine). (27 Sep 1997) |
| Haemophilus influenza b vaccine | <virology> A vaccination that is given to infants to protect against infection with haemophilus influenza b, an important cause of neonatal sepsis. Typically administered at 2, 4, 6 and 15 months. Children who are aged 15 months to 5 years, who have not received the vaccine, should be given a single injection of haemophilus b conjugate vaccine. Acronym: HIB (26 Mar 1998) |
| Haemophilus influenza meningitis | <disease> 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) |
| Hong Kong influenza | Influenza caused by a serotype of influenza virus type A and first identified in Hong Kong. (05 Mar 2000) |
