Fever

Fever is a temperature above 38°C and usually means the body is fighting an infection. Most fevers in adults are due to viral illness and settle within a few days with rest and fluids. See a GP promptly if fever is high, prolonged over 3 days, or accompanied by red-flag features such as breathlessness, confusion, rash, severe headache or dehydration.

When a routine GP appointment is fine

Questions a doctor may ask

  • · How high has the temperature been?
  • · How many days have you had the fever?
  • · Any cough, sore throat, urinary symptoms, diarrhoea or rash?
  • · Any recent travel?
  • · Any long-term conditions or immunosuppressive medication?
  • · How much fluid are you managing?

History factors that may matter

  • · Recent travel
  • · Immunosuppression or chemotherapy
  • · Chronic conditions (diabetes, kidney disease)
  • · Recent surgery or procedures

What may happen during the examination

  • · Temperature, pulse, blood pressure, respiratory rate, oxygen saturation
  • · Ears, nose, throat, chest, abdomen and skin examination
  • · Focused examination based on symptoms

Tests that may be considered

Blood tests

  • · Full blood count
  • · CRP
  • · Kidney and liver function
  • · Blood culture where sepsis suspected (hospital)
  • · Malaria film if travel-related
  • · Dengue serology where indicated

Urine tests

Other tests

  • · Throat swab where indicated
  • · Chest X-ray if respiratory infection suspected

When a specialist referral may be considered

  • · Infectious diseases for travel-related, prolonged or unexplained fever

Possible treatment approaches

  • · Fluids and rest

  • · Antibiotics only when a bacterial infection is confirmed or strongly suspected
  • · Antiviral or antimalarial treatment where indicated

Safe self-care

  • · Regular fluids — water, oral rehydration solution
  • · Rest
  • · Cool, light clothing (Dubai’s heat can worsen dehydration)
  • · Paracetamol for comfort if needed

Best avoided

Frequently asked questions

How high is a dangerous fever?+

Any fever above 39.5°C in an adult, or a fever with red-flag features (confusion, breathlessness, non-blanching rash, neck stiffness), needs urgent medical assessment. Elderly and immunocompromised people can be seriously unwell with lower temperatures.

Should I take antibiotics for fever?+

No — most fevers in adults are viral and antibiotics do not help. A doctor should assess whether antibiotics are appropriate based on the cause.

Can I get a home visit for fever in Dubai?+

Yes — our doctors and nurses provide same-day home visits across Dubai for fever assessment, bedside tests and treatment.
