4 diseases with persistent fever symptoms that should not be ignored

Mild fevers usually go away within 24 to 48 hours. Persistent fevers, even mild ones, can make you feel tired. In addition, persistent fevers can be a warning sign of an underlying illness.

Mild fever is a condition in which the body temperature rises above 37 degrees Celsius, but not over 38 degrees Celsius, and lasts for more than 24 hours. Persistent fever is a condition in which the fever lasts for more than 10 days. Therefore, if the fever does not go away after 24 hours, medication is needed, according to The Health Site .

Colds and flu can cause persistent fevers.

Persistent fever can be a sign of the following illnesses:

Respiratory tract infection

Common respiratory infections include colds, flu, pharyngitis, tonsillitis, sinusitis, bronchitis and pneumonia. Colds and flu are very common. The causative agents are viruses. The body responds by increasing body temperature to kill viruses and other disease-causing microorganisms.

Common symptoms of respiratory infections include runny nose, nasal congestion, sore throat, sneezing, cough and fatigue.

Urinary tract infections can cause persistent fever.

A persistent fever can also be a warning sign of a urinary tract infection. This is an infection caused by bacteria. In addition to fever, the patient will also have symptoms such as pain when urinating, frequent urination, and dark urine.

Stress

Chronic stress can cause persistent fever. This condition, called psychogenic fever, is common in young children and people with fibromyalgia or chronic fatigue syndrome (CFS).

Common fever-reducing medications such as paracetamol do not work to reduce fever caused by stress. Instead, patients need to take some medications that reduce stress and anxiety.

Tuberculosis

Tuberculosis is caused by the bacterium Mycobacterium tuberculosis. This bacterium can remain dormant in the body for many years. When the immune system weakens, the bacteria begin to attack the body, causing symptoms such as cough, unexplained fatigue, persistent fever and night sweats.

If the fever persists, the patient should see a doctor for examination and proper treatment. For infants and children under 3 months old, caregivers should not give the child medicine without consulting a doctor, according to The Health Site .
