Welcome to HCM
After going through history you suffered a URI that is Upper Respiratory Tract
Infection usually caused by virus,but some times it gets secondary bacterial infection,and there can be post infective bronchitis
That is why still cough
is present and fever
is persisting .
Please consult a Physician and after examination a CBC and Skiagram may be required and proper antibiotics and other medicines you will recover as early as possible.
Even persiparation is a part of your illness.
Please Take care
Good luck to you
