A fever is a temporary increase in your body's temperature, typically in response to an illness, infection, or inflammation. It is not a disease itself, but rather a sign that your body’s immune system is actively fighting off an intruder (like a virus or bacteria).
Understanding the types of fever, their patterns and associated fever symptoms helps determine when simple care may be enough and when professional diagnosis is necessary. Types of fevers vary depending on the cause. Knowing when to see a doctor for fever is vital, especially if symptoms worsen or persist beyond a few days.

10 Common Types of Fever in India
In India, common fevers include malaria, dengue, typhoid, chikungunya, and viral fevers. Fever symptoms like high temperature, chills, and fatigue are typical. Types of fever, such as acute fever or chronic fever, have varying durations.
- Acute Fever: Acute fever is a sudden onset of high temperature, typically caused by infections like malaria, dengue, or the flu. Fever symptoms include chills, body aches and fatigue. The fever causes are often viral or bacterial
- Subacute Fever: Subacute fever typically lasts longer than acute fever but shorter than chronic fever, often lasting from a few days to a few weeks. Common fevers like typhoid or chikungunya are subacute fevers
- Chronic Fever: Chronic fever is a prolonged fever that lasts for weeks or months, often linked to underlying conditions such as tuberculosis, autoimmune diseases, or certain cancers. Causes for chronic fever are often infections, inflammatory diseases, or malignancies
- Intermittent Fever: Intermittent fever is characterized by recurring episodes of fever with periods of normal temperature in between. Common fevers like malaria and tuberculosis often present as intermittent fever. Fever symptoms include sudden spikes in body temperature followed by periods of normal temperature, along with chills and fatigue. Causes of intermittent fever include infections, such as malaria or brucellosis
- Remittent Fever: Remittent fever is marked by fluctuating high temperatures that do not return to normal. Common fevers like typhoid and certain viral infections often present as remittent fever. Fever symptoms include persistent fever, fatigue and sweating
- Relapsing Fever: Relapsing fever is characterized by recurring episodes of fever, typically caused by bacterial infections like Borrelia. Fever symptoms include high temperature, chills, headache, and muscle aches. Types of fever, like acute fever or chronic fever, can also present as relapsing fever
- Hyperpyrexia: Hyperpyrexia is an extremely high fever, typically above 106°F (41°C), and is considered a medical emergency. It can result from severe infections, heatstroke, or neurological conditions. Fever symptoms include intense heat, confusion, sweating, and possible organ dysfunction
- Low-Grade Fever: Low-grade fever refers to a mild increase in body temperature, usually between 99°F to 100.4°F (37.2°C to 38°C). Common fevers like viral infections, tuberculosis, or mild bacterial infections often present as low-grade fever. Fever symptoms include slight chills, fatigue, and mild body aches
- Septic Fever: Septic fever is a high fever caused by a severe infection leading to sepsis, a life-threatening condition.Common fevers like those from bacterial infections, including pneumonia or urinary tract infections, can lead to sepsis. Fever symptoms include high temperature, chills, rapid breathing, confusion, and low blood pressure
- Drug-Induced Fever: Drug-induced fever occurs as a side effect of certain medications. Common fevers from drug reactions can be triggered by antibiotics, anticonvulsants, or nonsteroidal anti-inflammatory drugs .Fever symptoms include fever with no infection, rash, and joint pain
