Patients with upper respiratory tract infections who have fever need to take care of their diet and rest, and most of them will recover after about 1 week of treatment. Patients with upper respiratory tract infections can have different symptoms, not all of them have cough, nasal congestion and fever. If patients have fever, they should be given anti-inflammatory, antipyretic and antipyretic drugs, such as azithromycin and Qingkailing granules. However, if the patient continues to have fever after medication, he/she needs to go to the respiratory department of the hospital in time to check the blood routine and chest CT, etc. to clarify the specific condition and let the doctor take appropriate treatment instead of continuing medication treatment by himself/herself. The prevention of fever caused by upper respiratory tract infection is to have a reasonable diet, to consume more fresh vegetables and fruits, to pay attention to the combination of work and rest, not to stay up late, so as not to prolong the course of the disease due to the decline of immunity caused by exertion, and to have a limited use of air conditioning.
