My dad was admitted about a week ago. His white blood cell count was 16,800, but it's normal now. However, the Widal test came back positive at 1:160. He's on treatment with Pipzo 4.5g injections, Pantop, Ns 500ml, Nurostar injections, and taking Calpol 650 and Cefuroxime 500 twice a day. Is this the right approach? I'm a bit worried and could use some guidance.
