Fever is the body’s response to infection, inflammation or other illness. A medical review on fever explains that it can have many causes, and careful history and examination are important when fever is persistent or unexplained. Read the overview here: NCBI Bookshelf fever review.
Many adults get fever due to common viral infections. In such cases, rest, fluids and doctor-approved medicines may be enough. But not every fever is simple.
A high fever, fever lasting more than three days, repeated fever, fever with rash, severe headache, confusion, breathing difficulty, chest pain or persistent vomiting should be checked.
Fever with severe weakness can be serious, especially in older adults, pregnant women, people with diabetes, kidney disease, heart disease, cancer or low immunity.
In India, fever may be linked to viral infections, dengue, malaria, typhoid, flu, urinary infection, pneumonia or other causes. Symptoms and local disease patterns matter.
Do not take antibiotics without a doctor’s advice. Antibiotics do not work for viral fever, and unnecessary use can cause side effects and resistance.
Also avoid combining multiple fever medicines unless a doctor advises it. Too much paracetamol or unsafe painkiller use can harm the liver, kidneys or stomach.
A doctor may advise blood tests, urine tests, dengue or malaria tests, chest imaging or other checks depending on symptoms.
For people needing evaluation of fever, infection or chronic medical symptoms, Cura Hospitals provides information about its general medicine department.
Fever is common, but it should be taken seriously when it is severe, persistent or linked with warning signs.
Medical note: Seek urgent help for confusion, breathing difficulty, seizures, severe dehydration, very low blood pressure, severe headache with neck stiffness or fever in a high-risk patient.
