Autumn and winter are the high seasons of upper respiratory tract infections. Climate changes since the beginning of winter can easily cause coughs, especially for some people who have not healed for a long time. People with excessive or poor recurrence are chronic coughs. Most of these people start as soon as the season changes, and it is even more obvious for people with allergic constitutions. Many people can’t help but have the following questions: What is the difference between cough caused by COVID-19 and ordinary coughs?
There are many common causes of cough, including respiratory infections, such as viruses and bacterial infections; external inhalations stimulate the airway, causing high responsiveness of the airway, such as asthma; food allergies may also cause cough; mental factors, such as special tension, can also cause airway spasm, thereby inducing cough.
Nowadays, the prevention and control of the new coronavirus pneumonia epidemic is normalized, many people are very nervous about coughing, and even doubt whether it is related to the new coronavirus pneumonia. People with allergic cough do not have general discomfort symptoms such as fever or fatigue. There is a obvious characteristic when cough occurs, which is recurrent attacks. The so-called recurrent attack refers to the occurrence of a sensitive environment or exposure to sensitive substances (i.e., allergens), which causes cough. Some patients cough the most severely at night and in the morning, and even wake up in the middle of the night. They basically don’t cough or rarely cough during the day, but they will have severe coughs after exercise.
The initial symptoms of new coronary pneumonia are mainly fever, headache, muscle fatigue, general discomfort, which is difficult to distinguish from influenza. However, the most prominent symptoms of patients with COVID-19 are dyspnea and respiratory infection. Therefore, if you find that you have fever during a special period and have difficulty breathing, or chest tightness, asthma, and shortness of breathing, it is recommended to go to the hospital for examination in time. Judging from the symptoms alone, if you don’t have to be too nervous if you have simple cough symptoms (which are more severe in the morning), then it is likely that it is caused by allergic cough, not new coronary pneumonia. First make predictions about your cough symptoms and then seek medical attention in time.
At the same time, in daily life, everyone should pay attention to protecting themselves, maintain ventilation and breathability, strengthen physical exercise, and enhance their physical fitness, so as to effectively resist the troubles of allergens.
