Learn more about the signs and symptoms of a fever from NewYork-Presbyterian."],"attrs_boilerpipe_text":"What is a Fever?\nWhat is a Fever?\nA fever is a body temperature that is higher than average. It’s typically a sign of an immune system’s natural response to an infection or a virus.\nA person’s average normal body temperature is 98.6° Fahrenheit. For adults, a fever is when your body temperature is above 100.4°F. For children, a fever is a body temperature higher than 99.5°F (taken orally), 99°F (taken under the arm), or 100.4°F (taken rectally).\nFevers show that your body is working to fight off a virus or infection—a normal and healthy response. Most fevers can be treated at home, but there are certain situations where a fever can be cause for concern.\nTypes of Fevers\nTypes\nA fever is traditionally categorized by how high your temperature is and how long it lasts. There are five general types of fever, including:\nIntermittent fever -\nThis type of fever fluctuates between normal body temperature and higher-than-normal levels through the day\nRemittent fever -\nLike intermittent fever, this fever fluctuates throughout the day, but never falls all the way back to a baseline normal temperature\nHectic fever -\nWith hectic fever, temperatures swing severely throughout the day, with a difference of at least 1.4 degrees Celsius between the lowest and highest measurements. A remittent or intermittent fever can be considered hectic.  \nContinuous (or sustained) fever -\nContinuous fever is a steady, prolonged fever, with no change or slight fluctuations throughout the day\nRelapsing fever -\nThis type is an intermittent fever that spikes again after days or weeks of having a normal body temperature\nFevers can be considered mild, moderate, or high. What constitutes a fever temperature-wise varies between adults,\nchildren 11 and younger\n,\nkids 12 and older\n.\nFevers in infants (0 to 3 months) and sustained fevers in children, especially those under 2, warrant a call to\nyour pediatrician\n.\nSigns & Symptoms of Fevers\nSymptoms\nFever symptoms vary depending on the type of fever, the temperature, and the cause. A fever in adults can produce different symptoms than children may have. \nBeyond an elevated body temperature, fever symptoms can include:\nChills or shivering\nSweating\nHeadaches\nBody aches\nFatigue\nFeeling dehydrated\nLoss of appetite\nHot skin to the touch\nFlushed complexion\nA\nprimary care doctor\nor your child’s general pediatrician can help address these symptoms, locate the cause, and recommend a specialist or emergency care when necessary.\nContact your pediatric doctor if your baby is under 3 months and develops a fever.\nConditions with fever as a symptom\nA fever can be an indicator of many kinds of health issues, ranging from mild infections to severe diseases. Conditions that can have fever as a symptom include:\nCold\nor\nflu\nInfections, including of the ear, throat, skin, kidney or bladder\nCOVID-19\nStrep throat\nBronchitis\nUrinary tract infections (UTI)\nInflammatory conditions\n, such as rheumatoid arthritis\nMononucleosis\nBlood clots\nAutoimmune diseases, including\ninflammatory bowel disease (IBS)\nand lupus\nCancer\nHyperthyroidism and other hormone disorders\nWhen to see a doctor\nFevers are common and typically don’t require medical attention. They are a sign of a health issue, however, so it’s important to pay attention to your symptoms and know when to get help.\nIf your child has a fever, contact a physician if the following criteria applies or these symptoms appear:\nYour baby is younger than three months old\nA fever lasts longer than three days\nYour child is confused, listless, or has trouble making eye contact\nYour child vomits repeatedly\nHas ear pain or tugs on their ear\nDevelops a fever after being left in a hot car\nHas a fever-related seizure\nSeek medical attention for an adult fever right away if accompanied by the following symptoms:  \nStiff neck\nIrritability or confusion\nSeizure\nSevere headache\nDehydration (no tears, less urine, sunken eyes)\nSevere light sensitivity. (Photophobia)\nA rash\nPain when urinating\nAbdominal pain\nTrouble breathing\nVomiting\nA fever above 103°F lasting more than two hours after taking fever-reducing medicine\nAny adult fever above 105°F that doesn’t respond to home medication could be life-threatening. Call 911 immediately. \nWhat Causes a Fever?\nCauses\nYour body’s temperature is balanced by the area of the brain called the hypothalamus—your own interior thermostat. The hypothalamus makes temperature adjustments when the body encounters certain conditions, occasionally resulting in an elevated body temperature.\nFever causes can include:\nViral infection\nBacterial infection\nImmunization and vaccines\nMedication side effects\nTeething in babies (low-grade, lower than 102°)\nHeat exhaustion\nSunburn\nComplications\nComplications\nMost fevers subside on their own or with the help of fever-reducing remedies. But high, persistent fevers, or fevers that worsen over time, can result in brain damage or even death.\nFebrile or fever seizures\nare convulsions in children that a fever spike can cause. Fever seizures are not the same as epileptic seizures, lasting for 1 to 3 minutes, and are generally not serious.\nPrevention\nPrevention\nAnyone can develop a fever, but avoiding getting sick is the best way to prevent one. You can help prevent infections and other causes of fever by doing the following:\nWash your hands\nAvoid sharing silverware, cups, and other dining materials\nAvoid touching your face\nGet vaccinated against infectious diseases\n, including the flu and COVID-19\nCarry hand sanitizer\/wipes with you","attrs_markdown":"[Skip to main

It’s typically a sign of an immune system’s natural response to an infection or a virus. A person’s average normal body temperature is 98.6° Fahrenheit. For adults, a fever is when your body temperature is above 100.4°F. For children, a fever is a body temperature higher than 99.5°F (taken orally), 99°F (taken under the arm), or 100.4°F (taken rectally). Fevers show that your body is working to fight off a virus or infection—a normal and healthy response. Most fevers can be treated at home, but there are certain situations where a fever can be cause for concern. ## Types of Fevers Types A fever is traditionally categorized by how high your temperature is and how long it lasts. There are five general types of fever, including: - Intermittent fever - This type of fever fluctuates between normal body temperature and higher-than-normal levels through the day - Remittent fever - Like intermittent fever, this fever fluctuates throughout the day, but never falls all the way back to a baseline normal temperature - Hectic fever - With hectic fever, temperatures swing severely throughout the day, with a difference of at least 1.4 degrees Celsius between the lowest and highest measurements. A remittent or intermittent fever can be considered hectic. - Continuous (or sustained) fever - Continuous fever is a steady, prolonged fever, with no change or slight fluctuations throughout the day - Relapsing fever - This type is an intermittent fever that spikes again after days or weeks of having a normal body temperature Fevers can be considered mild, moderate, or high. What constitutes a fever temperature-wise varies between adults, [children 11 and younger](https://www.nyp.org/healthlibrary/document/fever-estimates-11-and-younger), [kids 12 and older](https://www.nyp.org/healthlibrary/symptoms/fever-or-chills-age-12-and-older). Fevers in infants (0 to 3 months) and sustained fevers in children, especially those under 2, warrant a call to [your pediatrician](https://www.nyp.org/pediatrics). ## Signs & Symptoms of Fevers Symptoms Fever symptoms vary depending on the type of fever, the temperature, and the cause. A fever in adults can produce different symptoms than children may have. Beyond an elevated body temperature, fever symptoms can include: - Chills or shivering - Sweating - Headaches - Body aches - Fatigue - Feeling dehydrated - Loss of appetite - Hot skin to the touch - Flushed complexion A [primary care doctor](https://www.nyp.org/primary-care) or your child’s general pediatrician can help address these symptoms, locate the cause, and recommend a specialist or emergency care when necessary. Contact your pediatric doctor if your baby is under 3 months and develops a fever. ### Conditions with fever as a symptom A fever can be an indicator of many kinds of health issues, ranging from mild infections to severe diseases. Conditions that can have fever as a symptom include: - [Cold](https://www.nyp.org/primary-care/common-cold) or [flu](https://www.nyp.org/primary-care/influenza-flu) - Infections, including of the ear, throat, skin, kidney or bladder - [COVID-19](https://www.nyp.org/primary-care/covid-19) - [Strep throat](https://www.nyp.org/primary-care/strep-throat) - [Bronchitis](https://www.nyp.org/primary-care/bronchitis) - [Urinary tract infections (UTI)](https://www.nyp.org/primary-care/urinary-tract-infection-utis) - [Inflammatory conditions](https://www.nyp.org/rheumatology), such as rheumatoid arthritis - [Mononucleosis](https://www.nyp.org/primary-care/mononucleosis-mono) - [Blood clots](https://www.nyp.org/vascular/dvt-blood-clots-and-thrombophlebitis) - Autoimmune diseases, including [inflammatory bowel disease (IBS)](https://www.nyp.org/digestive/inflammatory-bowel-disease) and lupus - [Cancer](https://www.nyp.org/cancer) - Hyperthyroidism and other hormone disorders ### When to see a doctor Fevers are common and typically don’t require medical attention. They are a sign of a health issue, however, so it’s important to pay attention to your symptoms and know when to get help. If your child has a fever, contact a physician if the following criteria applies or these symptoms appear: - Your baby is younger than three months old - A fever lasts longer than three days - Your child is confused, listless, or has trouble making eye contact - Your child vomits repeatedly - Has ear pain or tugs on their ear - Develops a fever after being left in a hot car - Has a fever-related seizure Seek medical attention for an adult fever right away if accompanied by the following symptoms: - Stiff neck - Irritability or confusion - Seizure - [Severe headache](https://www.nyp.org/neuro/headache) - Dehydration (no tears, less urine, sunken eyes) - Severe light sensitivity. (Photophobia) - A rash - Pain when urinating - Abdominal pain - Trouble breathing - Vomiting - A fever above 103°F lasting more than two hours after taking fever-reducing medicine Any adult fever above 105°F that doesn’t respond to home medication could be life-threatening.

Causes Your body’s temperature is balanced by the area of the brain called the hypothalamus—your own interior thermostat. The hypothalamus makes temperature adjustments when the body encounters certain conditions, occasionally resulting in an elevated body temperature. Fever causes can include: - Viral infection - Bacterial infection - Immunization and vaccines - Medication side effects - Teething in babies (low-grade, lower than 102°) - Heat exhaustion - Sunburn ## Complications Complications Most fevers subside on their own or with the help of fever-reducing remedies.
