The difference between upper respiratory tract infections and lower respiratory tract infections mainly lies in the location of the infection. The pathogen causing the infection could be the same. If an upper respiratory tract infection is not treated in time, the pathogen might infect downwards and cause a lower respiratory tract infection. Compared to upper respiratory tract infections, which are commonly seen in clinical practice, lower respiratory tract infections are less common. Therefore, whether it is an upper or lower respiratory tract acute inflammation, sufficient and sensitive antimicrobial drugs should be chosen according to the treatment course for proper treatment.

Symptoms of upper respiratory tract infection

The symptoms of upper respiratory tract infection mainly manifest as fever, sore throat, cough, difficulty breathing, and sputum production. Some cases may also present with signs of hypoxia, leading to phenomena like cyanosis of the lips. Firstly, drink plenty of water and measure body temperature. If there is acute inflammation, a sensitive antibiotic must be chosen, accompanied by antipyretic analgesic drugs to relieve symptoms. Additionally, taking medication to dilute the sputum and alleviate spasms of the bronchial smooth muscles is advised for symptomatic treatment. A treatment course generally requires five to ten days and regular follow-up checks are necessary. It is important to quit smoking and drinking, and to drink plenty of water.

How many days does an upper respiratory tract infection last?

Upper respiratory tract infections caused by common bacteria or viruses generally recover after about a week of treatment. If caused by Mycoplasma, the course of the disease is relatively longer, requiring about half a month to twenty days. If the upper respiratory tract inflammation is due to whooping cough or tuberculosis bacteria, the course of the disease will be even longer. Whooping cough requires at least half a month to twenty days of medication, while tuberculosis-induced respiratory infections need at least three to six months for full recovery. Common respiratory tract infections seen clinically generally recover completely within three to seven days, and the specific duration of the disease depends on the pathogen causing the infection.

How to treat upper respiratory tract infections?

In clinical treatment of upper respiratory infections, it is essential to analyze the specific course of the illness. In the early stages of viral infections, if symptoms such as cough, nasal congestion, and runny nose are present, antihistamines and antiviral medications for clearing heat and detoxification can be used for symptomatic treatment, such as 999 Cold Remedy Granules, antiviral oral liquids, etc. In later stages, if there is a concurrent bacterial infection with thick, yellow phlegm, treatment can include the combined use of antibiotics. Amoxicillin or cephalosporin antibiotics are possible choices.

Difference between acute upper respiratory tract infection and upper respiratory tract infection

In clinical terms, acute upper respiratory infection and upper respiratory infection usually mean the same thing, and there is no significant difference between them. Upper respiratory infections are typically acute, so sometimes they are simply referred to as upper respiratory infections without specifically mentioning 'acute.' Acute upper respiratory infections and upper respiratory infections generally have no difference; patients are often infected by viruses, typically presenting symptoms such as runny nose, sneezing, sore throat, coughing, and sometimes accompanied by fever. There may also be associated muscle soreness, fatigue, and headaches, but patients often experience low-grade fever rather than high fever. For these issues, symptomatic treatment is usually needed, and through such treatment, patients often recover on their own.

How is an upper respiratory tract infection caused?

Upper respiratory infections are mostly caused by pathogenic microorganisms. They are related to factors such as exposure to cold weather, low immunity, weak resistance, frequent staying up late, and excessive fatigue. Additionally, viral infections, such as influenza virus, adenovirus, rhinovirus, and Coxsackievirus, can also cause upper respiratory infections. Some may be due to bacterial infections. Therefore, it is recommended that everyone should actively seek symptom-targeted treatment under the guidance of a doctor, and it's important to identify the cause and develop an appropriate treatment plan based on test results. Key to the treatment is the active cooperation of the patient with the doctor's plan. In terms of diet, it is advised to eat light foods, drink plenty of water, rest adequately, and avoid spicy, greasy, raw, cold, and irritating foods. Smoking and drinking alcohol should also be avoided while actively cooperating with the treatment.
