Hello , I understand your concern. I am Dr. Arun Tank, infectious disease specialist, answering your concern. You have not tested for dengue for your wife. Dengue can also cause same symptoms. I advice you should take the dengue rapid test done under your doctors guidance. Once we have proper diagnosis we can start treatment accordingly. Till that time I advice you to take paracetamol for fever. Once you take the drug the fever will disappear. Please drink the water as much as your wife can drink. Fluid balance is very important in this case. Or you can say fluid therapy is the only cure for the dengue. I will be happy to answer your further concern you can contact me here or you can contact me on bit.ly/DrArun We wish you a best health at healthcare magic.
