Disease, kissing: Infectious mononucleosis (“mono”), a very common illness caused by the Epstein-Barr virus (EBV). By the time most people reach adulthood, an antibody against EBV can be detected in their blood meaning they have been infected with EBV. The illness is less severe in young children. The infection can be spread by saliva. Hence, the name: the kissing disease. The incubation period for “mono” is 4 to 8 weeks. Symptoms include fever, fatigue, sore throat, and swollen lymph glands. “Mono” can cause liver inflammation (hepatitis) and spleen enlargement. Vigorous contact sports should be avoided to prevent spleen rupture.
Infectious Mononucleosis Symptoms and Signs
- Disease, Kok
Disease, Kok: A genetic disorder also known as hyperekplexia in which babies have an exaggerated startle reflex (reaction). This disorder was not recognized until 1962 when it was described by Drs. Kok and Bruyn as a disease with the onset at birth of hypertonia (stiffness), exaggerated startle response, strong brain-stem reflexes (especially head-retraction reflex) and, […]
- Disease, Kostmann
Disease, Kostmann: A condition with a lack of neutrophils (a type of white blood cell that is important in fighting infection). Children with this disease suffer frequent infections from bacteria which in the past led to death in three-quarters of cases before 3 years of age. This disease is also known as severe congenital neutropenia […]
- Disease, Legionnaire
Disease, Legionnaire: A disease due to the bacteria Legionella pneumophila found in plumbing, shower heads, water-storage tanks and air cooling systems. Outbreaks of Legionella pneumonia have been attributed to evaporative condensers and cooling towers. The bacteria thrives in the mist sprayed from air-conditioning ducts and so it can infest an entire building or airplane. Travelers […]
- Disease, lipid storage
Disease, lipid storage: A series of disorders due to inborn errors in lipid metabolism resulting in the abnormal accumulation of lipids in the wrong places (Examples include Gaucher, Fabry and Niemann-Pick diseases and metachromatic leukodystrophy).
