Frequently asked questions
Do I always need antibiotics for an infection?
No — many infections are viral and do not respond to antibiotics. A specialist helps decide when they are truly needed to avoid resistance.
What tests diagnose typhoid, dengue and malaria?
Blood culture (best) or Widal for typhoid; NS1/IgM for dengue; blood smear or rapid test for malaria — chosen by the day of illness and symptoms.
