What is the reason for constant fever in a 9-month-old?

Hello,

Welcome to icliniq.com.

We are here to help you, and I am really sorry to hear about his state.

The clinical features and reports you have shown are indicative of the infection. But the infection looks like a bacterial origin because of predominantly elevated neutrophils and CRP. The common infections in this age group are urinary tract and respiratory tract, but other sites may get infected, for example, the abdomen. We do tests sequentially. I want to do a urine examination for routine and culture, and a blood culture should be repeated with an adequate amount of blood, and an ultrasound of the abdomen to look for any evidence of infection, for example, an abscess, pyelonephritis. Another thing is that we should repeat CBC and CRP to look for improvement.

And if your child is irritable with poor feeding, then we should also think of meningitis, which is an infection of the brain. For this, get a CECT head and lumbar puncture and examination of the CSF. Therapeutic intervention in your case, although Ceftriaxone is a good drug, but in such a young child, we should give a two-antibiotic combination, for example, Ceftriaxone and Amikacin. Because of the better coverage of the causative organism. If she has respiratory symptoms, then a chest X-ray is indicated, and after that, we can add other drugs depending on the findings of the X-ray.

So, ask your doctor to do all these interventions and monitoring of the inflammatory parameters. And review the detailed reports, or before that, if you need more discussion.

I hope this helps.

Feel free to reach out in case of any further queries.

Thank you.
