Having  a child with long-term or persistent  fever can be frustrating for both the parent and the pediatrician. On the one hand, you might not want to overreact or put a child in, rather than making unnecessary tests, because a child can be daha just a virus oc, but then you don’t want to miss anything that can be treated, and more importantly, the lady is very serious. Doctors often use a staged approach to managing this symptomatic child.

Long-Term Fire with Unknown Origin

Prolonged fever is a fever that lasts longer than normal, for example, lasting longer than seven to 10 days to wait for a simple viral infection. Antibiotics are usually not prescribed only because the child has a long-lasting fever. In many cases, there is no specific cause of fire and only stops.
Unknown fever (FUO) has often been described as having a fever of three weeks or more without a known cause one week after physicians attempting to understand the cause of fever.

Evaluation of a long-lasting child

If your doctor sees your child early in the illness, within the first three to five days, he or she may decide to observe your child after a full examination and depending on how good or ill your child appears. After that, if you maintain fever depending on your child’s other symptoms, your pediatrician will probably do more tests, such as a strep test and a blood count.
At this point, if your child still has fever, it should almost certainly be seen again. This is especially important because you think it has deteriorated. If you are not comfortable seeing your pediatrician, consider having a second opinion from another pediatrician or going to the emergency room at a pediatric hospital.
Further testing may include:
  • Chest X-ray
  • Urine analysis and urine culture
  • Blood culture
  • Testing for Mono
  • Repeat blood count
  • Liver function tests
  • PPD for testing tuberculosis
  • HIV testing
  • Sedimentation rate (ESR) and C-reactive protein (CRP) test
  • Viral respiratory panel
A detailed physical examination may provide other clues that seek classic pediatric disease symptoms, such as mouth ulcers, rash, swollen lymph nodes, or Kawasaki disease.
A few weeks after a child with unknown fever (FUO), testing for less common things is done. This may include an abdominal sonogram or CT scan to search for a secret abscess, stool cultures, an ANA (arthritis test), antibody test for thyroid function tests and other infections.
If all of this is normal, then tests for non-infectious fever causes such as young rheumatoid arthritis, malignancies and inflammatory bowel disease come later.
Cough, pneumonia, or sinus infection, such as the common cold can cause respiratory disease as a cause of fever. Walking pneumonia or mycoplasma pneumonia can cause high fever, and may also be a possible cause of symptoms. It is not unusual for this infection to last one to three weeks for the child to begin to show improvement.
