I just received my father blood test report and the results say IGG negative, IGM positive, and NS1 antigen negative. Does that mean he is diagnosed with dengue virus?

IgM positive suggests recent dengue infection. NS1 negative may indicate its past the early stage. Monitor fever, hydration, and platelets. Seek immediate care if symptoms worsen.

Take a CBC Test (Complete Blood Count) Test or Take a DENGUE IGG/IGM ANTIBODIES - RAPID - KA Test

I initially had a sinus headache, which gradually disappeared. After that, I have been having a fever for over 15 days. My urine test is normal, and my CBC blood report shows a marginally low platelet count of 1.49 lakh. The doctor prescribed only Paracetamol, which provides temporary relief for a few hours. Doctor, what could be the cause of this prolonged fever? I do not have any other symptoms besides fever and fatigue.
