I had sneezing episodes every early morning and night before sleeping since many days. On last tuesday evening I had got cold and fever with chills. The next day physician diagnosed as viral infection and gave azithromycin and oseltamivir. The fever has subsided now but its just the cold persisting. Today the reports for widal test were positive with titre 1:160, but the limitations of the test says that it may be positive in viral infections. What should I do next ?
