Glossary for Meningococcal disease

  • Acute meningitis: Acute meningitis is an inflammation of the brain that presents in an acute fashion. The inflammation may be the result of infective agents such as bacteria, viruses and fungi as well as non-infective agents such as certain drugs. Acute forms of meningitis can develop in within hours or days whereas chronic meningitis develops over weeks or months.
  • Anthrax meningitis: Anthrax meningitis is an infectious disease caused by breathing in the spores of the bacteria Bacillus anthracis.
  • Bacterial diseases: Diseases caused by a bacterial infection
  • Bacterial meningitis: Bacterial meningitis is a form of meningitis caused by bacteria that normally lives in the mouth and throat. When the immune system is unable to supress this bacteria, it travels to the cerebrospinal spinal fluid in the brain. From there it affects the membranes surrounding the brain.
  • Blood conditions: Conditions that affect the blood
  • Blood vessel damage: A condition characterized by damage to vessels that transport blood around the body
  • Brain abscess: Pus accumulating into an abscess on the brain
  • Brain cancer: Cancer of the brain.
  • Brain conditions: Medical conditions that affect the brain
  • Brain damage: Damage to the brain from various causes
  • Brain infection: Infection of the brain including encephalitis
  • Carcinomatous meningitis: Carcinomatous meningitis, is a form of metastatic cancer that has spread to the lining of the brain and spinal cord, the parts of the body that make up the central nervous system.
  • Chemical meningitis: Symptomatic aseptic, chemical meningitis is a rare complication of myelography. A number of these cases have a history of one or more episodes of chemical meningitis preceding their arachnoiditis.
  • Child health conditions: Any medical conditions typically afflicting children.
  • Chronic meningitis: Chronic meningitis is an inflammation of the meninges with subacute onset and persisting cerebrospinal fluid (CSF) abnormalities lasting for at least one month.
  • Coma: Prolonged unconsciousness
  • Common cold: A cold is a relatively minor contagious infection of the nose and throat that can be caused by a number of different viruses (e.g. rhinoviruses, coronaviruses). There are over 200 different viruses that have the potential to cause the common cold. Although colds can cause discomfort they are not considered a serious condition.
  • Conditions involving a pathogen: Medical conditions involving some type of pathogen, such as a virus or bacteria.
  • Deafness: Inability to hear sounds.
  • Death: The cessation of life
  • Delirium tremens: Delirium from alcohol withdrawal
  • Encephalitis: Dangerous infection of the brain
  • Eosinophilic meningitis: Eosinophilic meningitis is a distinct clinical entity that may have infectious and noninfectious causes. Worldwide, infection with the helminthic parasite, Angiostrongylus cantonensis, is the most common infectious etiology.
  • Flu: Very common viral respiratory infection.
  • Fungal meningitis: Fungal meningitis is an infection that causes swelling and irritation of the tissue around the brain and spinal cord. It usually strikes people whose weakened immune systems can't fight off infection. The disease is not common. but it can be very serious.
  • Group A Streptococcal Infections: "Strep" bacteria responsible for strep throat, impetigo and some other strep conditions.
  • High fever: Where a patient has an elevated temperature
  • Hydrocephalus: A rare condition where the normal flow of cerebrospinal fluid is impaired by dilated brain ventricles which causes the fluid to accumulate in the skull and hence result in increased brain pressure.
  • Hypocalcaemia: Decreased concentration of calcium in the blood.
  • Infectious meningitis: Infectious meningitis is meningitis caused by bacterial, viral, or protozoan infection. Most of the agents known to cause meningitis are infectious, but very few people exposed to them will get meningitis. Those at greatest danger include people with AIDS, infants, transplant patients, and others whose immune systems may be compromised.
  • Invasive group A Streptococcal disease: Infection with Group A Streptococcal bacteria
  • Jequier-Deonna Syndrome: A very rare condition described in two sisters. It is characterized by vision and hearing problems and incoordination.
  • Kidney failure: Total failure of the kidneys to filter waste
  • Meningitis: Dangerous infection of the membranes surrounding the brain.
  • Meningococcal A: Meningococcal meningitis is an infection that causes inflammation of the membranes covering the brain and spinal cord. Meningococcal meningitis A is caused by meningococcus A which is mostly common in hyperendemic areas in Africa known as the meningitis belt.
  • Meningococcal B: Meningococcal meningitis B is an infection that causes inflammation of the membranes covering the brain and spinal cord.
  • Meningococcal C: Meningitis C is a strain of meningococcal meningitis, a bacterial infection of the membranes surrounding the brain and spinal cord.
  • Meningococcal disease: Dangerous bacterial infection causing meningitis or bacteremia.
  • Meningococcemia: A rare infectious disease whose main symptoms are upper respiratory tract infection, fever, rash and eye and ear problems.
  • Meningoencephalitis: A condition which is characterized by inflammation of the brain and meninges
  • Mental retardation -- dysmorphism -- hypogonadism -- diabetes: A very rare syndrome characterized mainly by mental retardation, hypogonadism, diabetes and facial and skull abnormalities.
  • Migraine: Chronic recurring headaches with or without a preceding aura.
  • Myocarditis: Inflammation of the myocardium (muscle walls of the heart)
  • Nausea: The queasy feeling of nausea and often also vomiting.
  • Nervous system conditions: Diseases affecting the nerves and the nervous system.
  • Pneumococcal meningitis: Pneumococcal meningitis is an inflammation or infection of the membranes covering the brain and spinal cord caused by Streptococcus pneumoniae (also called pneumococcus).
  • Properdin deficiency, X-linked: A rare condition where an inherited deficiency of properdin (a blood plasma component) affects immunity. In particular, susceptibility to Neisseria infections is increased.
  • Purpura: Various bruising conditions where small blood vessels hemorrhage
  • Septic shock: serious medical condition caused by decreased tissue perfusion and oxygen delivery as a result of infection and sepsis, though the microbe may be systemic or localized to a particular site
  • Septicemia: A systemic inflammatory response to an infection.
  • Severe headache: A condition which is characterized by a severe headache
  • Shock: Severe condition from reduced blood circulation
  • Streptococcal Infections: Various "strep" bacterial infections.
  • Subarachnoid haemorrhage: A condition which is characterized by haemorrhage of blood into the subarachnoid space
  • Tuberculous meningitis: Tuberculous meningitis is an infection of the membranes covering the brain and spinal cord caused by Koch's bacillus.
  • Type A influenza subtype H1: The H1 subtype of influenza is a strain of the type A influenza virus that can cause cause serious illness and result in pandemics. Influenza is viral respiratory infection. The virus is very contagious and can cause severe illness especially in patients who are very young or old or have some other medical condition as well. The severity of symptoms can vary but usually involves respiratory and constitutional (e.g. headache, aching muscles) symptoms. The influenza virus can mutate and produce different strains though the symptoms are the same. This frequent mutation means that people need regular vaccinations to ensure they are protected against new strains as they arise.
  • Vasculitis: Inflammation of a blood or lymph vessel
  • Viral diseases: Any disease that is caused by a virus
  • Viral meningitis: Viral meningitis refers to meningitis caused by a viral infection
  • Vomiting: Vomiting or retching symptoms.
  • Waterhouse-Friderichsen syndrome: The malignant form of cerebrospinal meningitis
