Have Fever, Cough, Feeling Fatigue And Noticed Red Itchy Rash. Sign Of Any Illness?
Thanks for posting your query.
I understand your concern as a vigilant parent.
Please do not worry.
Considering the details you have provided it does seem that your child is most probably suffering from a viral infection in which usually the fever is accompanied /followed with other symptoms like a rash (exanthem) and oral mucosal lesions ( enanthem).Its very difficult to confirm the exact virus causing it even with tests however majority of them do not require any specific treatment hence its not mandatory to carry out any tests if clinical diagnosis has been done by your doctor.
The sore tongue and papules on face should self resolve in a week with or without supportive therapy ( like multivitamin zinc supplements , local applicants for soothing etc).
The only significant thing to be ruled out is wether the bumps and sore tongue are in response or allergy to any medication given to the child in which case such a drug induced reaction will not subside on its own unless the inducing agent is stopped and anti allergy medications started.
Assuming you haven't mentioned any new medication or antibiotics started before the onset of her symptoms I do think that it is unlikely to be an allergic or drug reaction .
So as your doctor has mentioned to you , it does seem most probably a viral flu which should usually resolve in 2-3 weeks .
If you still would want a confirmation of the diagnosis a complete blood count and a throat swab would be helpful.
As far as your concern for your infant, I would advise you try to take usual hygienic precautions to prevent the spread of infection( hand hygiene, avoiding spread of nasal and oral secretions etc). It's important because even mild viral infections can be very significantly effect the health of infants whose immune system is physiologically immature to fight off any infection.Also it's advisable to watch your infant for any similar symptoms and get prompt medical help if needed.
I would appreciate that you follow up with your doctor for monitoring your child's progress and if needed your doctor can carry out further investigations as per need .
Hope I have answered your query.
Ill be available for any follow up queries.
