Respiratory tract infection
The difference between upper respiratory tract infection and lower respiratory tract infection.
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.
What should I do about a respiratory infection?
Respiratory infections are the most common type of infection encountered in both clinical and daily life, primarily divided into upper and lower respiratory tract infections. An upper respiratory tract infection, commonly referred to as a cold, is mainly characterized by nasal congestion, runny nose, and sore throat, and is mostly caused by viral infections. In the early stages, antiviral medication can be taken, and by checking a complete blood count, one can preliminarily determine whether the infection is viral or bacterial, deciding whether antibiotics are needed for treatment. Lower respiratory tract infections, on the other hand, are often caused by conditions such as pneumonia or bronchitis, which are mostly bacterial infections requiring targeted antibiotic treatment. For patients who are physically weaker, immunocompromised, or elderly and frail, there may also be a possibility of fungal co-infection, necessitating the use of antifungal medications for treatment.
Is an upper respiratory infection contagious?
Upper respiratory infections are contagious to some extent, as they are mostly caused by common pathogens such as rhinoviruses, streptococci, bacteria, mycoplasma, and other infectious agents. Clinically, they encompass a variety of diseases, including acute rhinitis, sinusitis, pharyngitis, tonsillitis, bronchiolitis, pneumonia, etc. These infections often spread through close contact and airborne droplets. Whether an individual gets infected mainly depends on the body's immune response. If a person has been vaccinated against a contagious disease and has developed antibodies, they generally will not be infected.
How to treat upper respiratory tract infections
If an upper respiratory tract infection is severe, it is necessary to take anti-inflammatory and anti-infection medications under the guidance of a doctor. The first and most important step is to identify the cause of the infection under medical supervision and then use medication accordingly, which is crucial. Additionally, it is advised to support the treatment by drinking more water, resting adequately, avoiding overexertion, and eating a bland diet without spicy, greasy, or cold and irritating foods. An upper respiratory tract infection may also be accompanied by fever. If the body temperature exceeds 38.5℃, fever-reducing medications should be taken. Moreover, it is important to drink plenty of water to promote excretion. If the body temperature is between 37.5℃ and 38.5℃, physical cooling methods can be used. It is also recommended to rest well, frequently ventilate indoor spaces, and ensure air remains fresh and circulating.
How to treat respiratory tract infections?
Respiratory infections are common situations in both clinical and daily life. The focus of treating respiratory infections is to identify the cause. For example, upper respiratory infections are most commonly caused by viral infections, primarily presenting symptoms such as coughing, sputum production, nasal congestion, runny nose, and sore throat, and may be accompanied by fever. The treatment can involve taking antiviral medications and nonsteroidal anti-inflammatory drugs to reduce fever when it occurs. For lower respiratory infections, such as lung infections, these are often due to bacterial infections. Identifying the type of bacteria through blood or sputum cultures can allow for targeted antibiotic treatment. It is important to avoid catching colds, exercise regularly, and improve overall fitness to prevent respiratory infections.
What medicine to take for respiratory infection?
If there are signs of a respiratory infection, it is mostly caused by bacteria, viruses, and other microbial infections. It is advised to undergo a routine blood test under the guidance of a doctor to determine the type of infection, and then to treat it with appropriate anti-infective medication as directed by a doctor. Symptomatic treatment should also be given. Common symptoms of respiratory infections include coughing, sputum production, and sore throat. During such times, it's advisable to take cough suppressants and expectorants, or use throat lozenges to alleviate sore throat. Additionally, drinking more water to aid metabolism and enhance immunity, eating a light diet, avoiding staying up late, maintaining a relaxed mood, and avoiding excessive stress or emotional excitement are recommended.
