The blood routine is mainly high in white blood cells and lymphocytes, and low in C-reactive protein, suggesting that virus infection is the main cause of upper respiratory tract infection. But now doctors are used to treating viruses and bacteria together, so it is diagnosis: virus and bacterial infection. The doctor prescribed anti-virus, anti-inflammatory, antipyretic and antitussive drugs for him.
I think it is doubtful that you should ask yourself this question. As for whether to continue to eat, to be honest, you don't have to, but in order to prevent bacterial infection, the doctor wants you to use it.
My suggestion: at present, some low-grade antibiotics can be used to resist disease, relieve cough and reduce fever, because I am not familiar with the condition, so I won't talk about the specific drugs.
