Fever blisterA small sore situated on the face or in the mouth that causes pain, burning, or itching before bursting and crusting over. The favorite locations are on the lips, chin or cheeks and in the nostrils. Less frequented sites are the gums or roof of the mouth (the palate).
RELATED TERMS--------------------------------------
Pain
An unpleasant sensory or emotional experience primarily associated with tissue damage, or described in terms of tissue damage, or both.
Chin
Medically, the mentum. The lower portion of the face below the lower lip including the prominence of the lower jaw and the line of fusion of the two separate halves of the jawbone (mandible). This line of fusion (called the symphysis menti) encloses a triangular area at tip of the chin (termed the mental protuberance). On each side, below the second premolar tooth, is the mental foramen, an opening for the passage of blood vessels and a nerve that supply the chin.
SIMILAR TERMS--------------------------------------
Fever
When body temperature rises above its normal level - defined as 98.6 degrees F, though it varies by individual and time of day. A fever is the sign of an immune system at work and usually indicates an infection.
Fever with renal syndrome, hemorrhagic
A set of diseases, also known as hemorrhagic fever, characterized by the abrupt onset of high fever and chills, headache, cold and cough, and pain in the muscles, joints and abdomen with nausea and vomiting followed by bleeding into the kidney and elsewhere.
Fever, breakbone
An acute mosquito-borne viral illness of sudden onset that usually follows a benign course with headache, fever, prostration, severe joint and muscle pain, swollen glands (lymphadenopathy) and rash. The presence (the "dengue triad") of fever, rash, and headache (and other pains) is particularly characteristic. Better known as dengue, the disease is endemic throughout the tropics and subtropics. It goes by other names including dandy fever. Victims of dengue often have contortions due to the intense joint and muscle pain.
Fever, cat scratch
A bacterial infection due to a cat scratch seen most often today in people with HIV. The disease characteristically presents with swollen lymph nodes (lymphadenitis), sore throat, fatigue, and fever, chills, sweats, vomiting, loss of appetite, and weight loss. There is usually a little bump (a papule) which may be pus-filled (a pustule) at the site of the scratch. Then more nodules appear on and under the skin. As the number of nodules increases, patients get sicker.

Fever, dengue hemorrhagic (DHF)
A syndrome due to the dengue virus that tends to affect children under 10, causing abdominal pain, hemorrhage (bleeding) and circulatory collapse (shock). DHF starts abruptly with high continuous fever and headache plus respiratory and intestinal symptoms with sore throat, cough, nausea, vomiting, and abdominal pain. Shock occurs after 2 to 6 days with sudden collapse, cool clammy extremities, weak thready pulse, and blueness around the mouth (circumoral cyanosis). There is bleeding with easy bruising, blood spots in the skin (petechiae), spitting up blood (hematemesis), blood in the stool (melena), bleeding gums and nosebleeds (epistaxis). Pneumonia and heart inflammation (myocarditis) may be present. The mortality is appreciable ranging from 6 to 30%. Most deaths occur in children. Infants under a year of age are especially at risk of death. DHF is also called Philippine, Thai, or Southeast Asian hemorrhagic fever and dengue shock syndrome.
Fever, desert
A disease also called coccidioidomycosis (CM) due to a fungus called Coccidioides immitis. About 40% of people infected with this fungus develop symptoms. Most often they have an influenza-like illness with fever, cough, headaches, rash, and myalgias (muscle pains). Of those people with symptoms, 8% have severe lung disease requiring hospitalization and 7% develop disseminated infection (throughout the body).
Fever, dumdum
Also called kala-azar, a chronic, potentially fatal parasitic disease of the viscera (the internal organs) due to infection by an agent called Leishmania donovani.
Fever, Ebola virus

Fever, Pontiac
A flu-like illness caused by the bacterium Legionella pneumophila contracted by breathing mist that comes from a water source (such as air conditioning cooling towers, whirlpool spas, showers) contaminated with the bacteria. The incubation period is short, from a few hours to 2 days, before the onset of fever and muscle aches. Persons with Pontiac fever do not have pneumonia. They generally recover in 2 to 5 days without treatment. Pontiac fever is so-named because of an outbreak in 1968 in Pontiac, Michigan. It is a milder form of legionellosis than Legionnaire disease which is caused by the same bacterium.
Fever, puerperal
Fever that lasts for more than 24 hours within the first 10 days after a woman has had a baby. Puerperal fever is due to an infection, most often of the placental site within the uterus. If the infection involves the bloodstream, it constitutes puerperal sepsis. Puerperal fever has gone by a number of different names including childbirth fever, childbed fever and postpartum fever. In Latin a "puerpera" is a woman in childbirth since "puer" means child and "parere" means to give birth. The puerperium is the time immediately after the delivery of a baby.
Fever, Q
An acute febrile illness due to Coxiella burnetii (C. burnetii), a species of bacteria. Q fever is a zoonotic disease (contracted from animals). Aside from sudden onset of fever, there is headache, malaise, and pneumonia but no rash.
Fever, quintan
Quintan means recurring every 5 days, the characteristic duration of trench fever.
Fever, relapsing
An acute infection with recurrent episodes of fever caused by spirochetes of the genus Borrelia which are borne by ticks or lice. The relapsing nature of the fever is associated with the presence of antigenic variants. As an immune response develops to the predominant antigenic strain, variant strains multiply and cause a recrudescent infection.
Fever, remittent
A type of fever that gradually decreases in intensity over time.
Fever, rheumatic
An illness that occurs following a streptococcus infection (such as a "strep throat") or scarlet fever and predominantly affects children. Symptoms include fever, pain in the joints, nausea, stomach cramps, and vomiting. Rheumatic fever can cause long-lasting effects in the skin, joints, heart, and brain.
Fever, Rift Valley
A viral disease that is acute, causes fever in domestic animals (such as cattle, buffalo, sheep, goats, and camels) and humans, and is associated with mosquito-borne epidemics during years of heavy rainfall. Rift Valley fever is more deadly than West Nile virus.
Fever, Rocky Mountain spotted (RMSF)

There is bleeding with easy bruising, blood spots in the skin (petechiae), spitting up blood (hematemesis), blood in the stool (melena), bleeding gums and nosebleeds (epistaxis). Pneumonia and heart inflammation (myocarditis) may be present. The mortality is appreciable ranging from 6 to 30%. Most deaths occur in children. Infants under a year of age are especially at risk of death.
Fever, splenic
Known also as anthrax, splenic fever is a serious bacterial infection. It is not primarily a human disease but rather an infection of animals. Cattle, sheep, horses, mules, and some wild animals are highly susceptible. Humans (and swine) are generally resistant to anthrax. Anthrax can take different forms. With the lung form of the disease. People inhale the anthrax spores and, if untreated, are likely to die. An intestinal form is caused by eating meat contaminated with anthrax. But most human anthrax comes from skin contact with animal products. Cutaneous (skin) anthrax was once well known among people who handled infected animals, like farmers, woolsorters, tanners, brushmakers and carpetmakers in the days when the brushes and carpets were animal products. The hallmark of skin anthrax is a carbuncle, a cluster of boils, that ulcerates in an ugly way. Typically this lesion has a hard black center surrounded by bright red inflammation.

Fever, typhoid
An acute illness with fever caused by infection with the Salmonella typhi bacteria contracted from contaminated water and food. The disease has an insidious onset characterized by fever, headache, constipation, malaise, chills, and myalgia (muscle pain). Diarrhea is uncommon, and vomiting is not usually severe. Confusion, delirium, intestinal perforation, and death may occur in severe cases. Without therapy, the illness may last for 3 to 4 weeks and death rates range between 12% and 30%. The disease is transmitted through contaminated drinking water or food. Large epidemics are most often related to fecal contamination of water supplies or street vended foods. A chronic carrier state -- excretion of the organism for more than 1 year -- occurs in approximately 5% of cases. Typhoid Mary was a chronic carrier.
Fever, undulant
An infectious disease due to the bacteria Brucella that characteristically causes rising and falling fevers, sweats, malaise, weakness, anorexia, headache, myalgia (muscle pain) and back pain. The disease is called undulant fever because the fever is typically undulant, rising and falling like a wave. It is also called brucellosis after its bacterial cause.
Fever, valley
A disease also called coccidioidomycosis (CM) due to a fungus called Coccidioides immitis. About 40% of people infected with this fungus develop symptoms. Most often they have an influenza-like illness with fever, cough, headaches, rash, and myalgias (muscle pains). Of those people with symptoms, 8% have severe lung disease requiring hospitalization and 7% develop disseminated infection (throughout the body).

Fever, yellow
An acute systemic (bodywide) illness caused by a virus called a Flavivirus. In severe cases, the viral infection causes a high fever, bleeding into the skin, and necrosis (death) of cells in the kidney and liver. The damage done to the liver from the virus results in severe jaundice which yellows the skin.
Feverfew
An herb that has been most commonly used for migraine headaches.
PREVIOUS AND NEXT TERMS--------------------------------------
Fetal rubella effects
The constellation of abnormalities, also called the rubella syndrome, caused by infection with the rubella (German measles) A virus before birth. The syndrome is characterized by multiple congenital malformations (birth defects) and mental retardation. The individual features of the syndrome include growth retardation, microcephaly (abnormally small head), cataracts, glaucoma, microphthalmia (abnormally small eyes), cardiovascular malformations, hearing loss, and mental retardation. Deafness is common. After birth the child may develop diabetes due to gradual destruction of the pancreas by the rubella virus.
Fetal surgery
The surgical treatment of the fetus before birth. Also called prenatal or antenatal surgery. Fetal surgery is done when the fetus is not expected to live long enough to make it through to delivery or to live long after birth unless fetal surgery is performed. For instance, if a fetus has a severe form of congenital diaphragmatic hernia, in which the liver is located in the chest and lung development is severely restricted, fetal surgery is done to lessen the severity of the problem and permit the baby to live to birth to undergo further corrective surgery. Fetal surgery can be done in various ways. Fetoscopic surgery uses a fiberoptic scope to enter the uterus through small surgical openings. The aim is to correct congenital malformations (birth defects) without major incisions and without removing the fetus from the womb. This is generally less traumatic than open fetal surgery and reduces the chances of preterm (premature) labor.
Fetoprotein, alpha (AFP)
AFP is a plasma protein that is normally produced by the fetus. It serves as the basis for some valuable tests.
Fetoscope
(1) A flexible fiberoptic device used to view or operate upon a fetus within the womb (to do fetal surgery).(2) A stethoscope designed for listening to the fetal heart beat.

Occurs only in the Western Hemisphere. Anyone frequenting tick-infested areas is at risk for RMSF.
Fever, Thai hemorrhagic
A syndrome due to the dengue virus that tends to affect children under 10, causing abdominal pain, hemorrhage (bleeding) and circulatory collapse (shock). Known also as dengue hemorrhagic fever (DHF), it starts abruptly with high continuous fever and headache plus respiratory and intestinal symptoms with sore throat, cough, nausea, vomiting, and abdominal pain. Shock occurs after 2 to 6 days with sudden collapse, cool clammy extremities, weak thready pulse, and blueness around the mouth (circumoral cyanosis). There is bleeding with easy bruising, blood spots in the skin (petechiae), spitting up blood (hematemesis), blood in the stool (melena), bleeding gums and nosebleeds (epistaxis). Pneumonia and heart inflammation (myocarditis) may be present. The mortality is appreciable ranging from 6 to 30%. Most deaths occur in children. Infants under a year of age are especially at risk of death. It is also called Philippine or Southeast Asian hemorrhagic fever and dengue shock syndrome.
Fever, trench
A disease borne by body lice that was first recognized in the trenches of World War I, when it is estimated to have affected more than a million people in Russia and on the fronts in Europe. Trench fever was again a major problem in the military in World War II and is seen endemically in Mexico, Africa, E. Europe, and elsewhere.
Fever, typhoid
An acute illness with fever caused by infection with the Salmonella typhi bacteria contracted from contaminated water and food. The disease has an insidious onset characterized by fever, headache, constipation, malaise, chills, and myalgia (muscle pain). Diarrhea is uncommon, and vomiting is not usually severe. Confusion, delirium, intestinal perforation, and death may occur in severe cases. Without therapy, the illness may last for 3 to 4 weeks and death rates range between 12% and 30%. The disease is transmitted through contaminated drinking water or food. Large epidemics are most often related to fecal contamination of water supplies or street vended foods. A chronic carrier state -- excretion of the organism for more than 1 year -- occurs in approximately 5% of cases. Typhoid Mary was a chronic carrier.
Fever, undulant
An infectious disease due to the bacteria Brucella that characteristically causes rising and falling fevers, sweats, malaise, weakness, anorexia, headache, myalgia (muscle pain) and back pain. The disease is called undulant fever because the fever is typically undulant, rising and falling like a wave. It is also called brucellosis after its bacterial cause.
Fever, valley
A disease also called coccidioidomycosis (CM) due to a fungus called Coccidioides immitis. About 40% of people infected with this fungus develop symptoms. Most often they have an influenza-like illness with fever, cough, headaches, rash, and myalgias (muscle pains). Of those people with symptoms, 8% have severe lung disease requiring hospitalization and 7% develop disseminated infection (throughout the body).
Fever, West Nile
A febrile disease caused by the West Nile virus that is transmitted from birds to the common Culex mosquito and then to people. The virus is named after the area it was first found in Uganda.
Fever, Wolhynia
Also known as trench fever, a disease borne by body lice that was first recognized in the trenches of World War I, when it is estimated to have affected more than a million people in Russia and on the fronts in Europe.
Fever, yellow
An acute systemic (bodywide) illness caused by a virus called a Flavivirus. In severe cases, the viral infection causes a high fever, bleeding into the skin, and necrosis (death) of cells in the kidney and liver. The damage done to the liver from the virus results in severe jaundice which yellows the skin.
Feverfew
An herb that has been most commonly used for migraine headaches.

Fetal rubella effects
The constellation of abnormalities, also called the rubella syndrome, caused by infection with the rubella (German measles) A virus before birth. The syndrome is characterized by multiple congenital malformations (birth defects) and mental retardation. The individual features of the syndrome include growth retardation, microcephaly (abnormally small head), cataracts, glaucoma, microphthalmia (abnormally small eyes), cardiovascular malformations, hearing loss, and mental retardation. Deafness is common. After birth the child may develop diabetes due to gradual destruction of the pancreas by the rubella virus.
Fetal surgery
The surgical treatment of the fetus before birth. Also called prenatal or antenatal surgery. Fetal surgery is done when the fetus is not expected to live long enough to make it through to delivery or to live long after birth unless fetal surgery is performed. For instance, if a fetus has a severe form of congenital diaphragmatic hernia, in which the liver is located in the chest and lung development is severely restricted, fetal surgery is done to lessen the severity of the problem and permit the baby to live to birth to undergo further corrective surgery. Fetal surgery can be done in various ways. Fetoscopic surgery uses a fiberoptic scope to enter the uterus through small surgical openings. The aim is to correct congenital malformations (birth defects) without major incisions and without removing the fetus from the womb. This is generally less traumatic than open fetal surgery and reduces the chances of preterm (premature) labor.
Fetoprotein, alpha (AFP)
AFP is a plasma protein that is normally produced by the fetus. It serves as the basis for some valuable tests.
Fetoscope
(1) A flexible fiberoptic device used to view or operate upon a fetus within the womb (to do fetal surgery).(2) A stethoscope designed for listening to the fetal heart beat.
FEV1
Forced Expiratory Volume in the first second. The volume of air that can be forced out in one second after taking a deep breath, an important measure of pulmonary function.
Fever blister
Fever with renal syndrome, hemorrhagic
A set of diseases, also known as hemorrhagic fever, characterized by the abrupt onset of high fever and chills, headache, cold and cough, and pain in the muscles, joints and abdomen with nausea and vomiting followed by bleeding into the kidney and elsewhere.
Fever, breakbone
An acute mosquito-borne viral illness of sudden onset that usually follows a benign course with headache, fever, prostration, severe joint and muscle pain, swollen glands (lymphadenopathy) and rash. The presence (the "dengue triad") of fever, rash, and headache (and other pains) is particularly characteristic. Better known as dengue, the disease is endemic throughout the tropics and subtropics. It goes by other names including dandy fever. Victims of dengue often have contortions due to the intense joint and muscle pain.
Fever, cat scratch
A bacterial infection due to a cat scratch seen most often today in people with HIV. The disease characteristically presents with swollen lymph nodes (lymphadenitis), sore throat, fatigue, and fever, chills, sweats, vomiting, loss of appetite, and weight loss. There is usually a little bump (a papule) which may be pus-filled (a pustule) at the site of the scratch. Then more nodules appear on and under the skin. As the number of nodules increases, patients get sicker.
Fever, dandy
An acute mosquito- borne viral illness of sudden onset that usually follows a benign course with headache, fever, prostration, severe joint and muscle pain, swollen glands (lymphadenopathy) and rash. The presence (the "dengue triad") of fever, rash, and headache (and other pains) is particularly characteristic. Better known as dengue, the disease is endemic throughout the tropics and subtropics. It goes by other names including breakbone fever. Victims of dengue often have contortions due to the intense joint and muscle pain
