Hello and welcome to HCM,
First of all i would like to say that when i went through the details description of your daughter sufferings, i couldn't wait and had to pick up the question to answer. I got worried to know that a small child of 4 years is suffering from such a high peaks of fever for so long. I have repeatedly went through your question four to five times and with the information given by you, i think...
Your daughter might need -
(1) Antibiotic course (I prefer Macrolid such as Azithromycin
More tests, she should undergo are -
(2) Pf Pv RT Kit test (For Malaria
I have not mentioned the drugs name and prescription details as not allowed by HCM.
Now the question is, why did i say so ???. Please allow me to explain-
I agree that virus (Particularly RSV) may be the cause of the problem, as Chest X Ray
reflects it, BUT i have seen in my clinical practice that, there is also super added bacterial infections along with it. It is again not always necessarily reflects in WBC count
. Also most viral fever
subsides within 5 to 7 days and generally it doesn't continue long enough. All the tests done is normal in your daughters case except the CXR & Urine culture (which was also normal first time and slight change in the second only). I personally feel that its high time she should be offered an antibiotics as she touched 7 days. Whatever be the reports. Because , i always do not lean back on laboratory reports. I think on history & clinical assessments. Here only from the history you presented, i am feeling that she needs antibiotics coverage. Secondly, multivitamin will boost her nutrition and so strengthening her immunity to fight back.
As you are worried whether any tests left to be done, in my opinion, i would advise those two tests more for exclusion. Suggestions i have given here are based on my clinical experiences and day to day practice only
Lastly, from this mail, i can only say you that, have faith on God and yourself. I am sure that your daughter is strong enough to fight back with her situation and will come out from it soon. I wish her a very very early recovery and a healthy life ahead. Please do not worry
