I underwent treatment for typhoid with cefixime 200 for 8-9 days. I was simultaneously diagnosed with Covid-19 and took Azithromycin-500 for 5 days. All my symptoms like fever and cough etc disappeared. But after 2 days of quitting medicine  there is again little fever under 100. I am feeling symptoms of Typhoid again. I had typhoid in February last year also. So I want to know which test can clarify typhoid fever in my case?
