Why asthma after recovery from novel coronavirus infection

In general, asthma following recovery from a novel coronavirus infection may be caused by genetic factors, environmental factors, psychological factors, climatic factors, exercise-related factors, etc. The specific analysis is as follows:

1. Genetic factors

After recovery from a novel coronavirus infection, the body's immune system may be weakened due to viral invasion. If one's parents have asthma, this may trigger asthma in their children. Patients can use medications such as budesonide suspension for inhalation and salbutamol sulfate inhaler under medical guidance to suppress bronchospasm.

2. Environmental factors

Long-term smoking or exposure to polluted environments may trigger asthma, leading to the aforementioned condition. Therefore, after recovering from a novel coronavirus infection, it is important to ventilate rooms regularly and clean them using disinfectants. If an asthma attack occurs, patients may use acetylcysteine solution for nebulization or fluticasone propionate suspension for nebulization as directed by a physician.

3. Psychological factors

Prolonged mental stress may also trigger this condition. Abnormal contraction of the bronchial walls can restrict normal airflow, resulting in symptom flare-ups. In such cases, patients should promptly use medications such as levosalbutamol hydrochloride solution for nebulization or ipratropium bromide solution for inhalation as prescribed.

4. Climatic factors

Extreme climates—either too cold or too hot—may cause air entering the bronchi to irritate the bronchial walls, thereby triggering asthma. Besides using medications such as fluticasone furoate nasal spray or levocetirizine hydrochloride tablets as directed by a doctor, patients should also pay attention to staying warm or cooling down appropriately.

5. Exercise factors

Engaging in overly intense physical activity may accelerate blood flow and overburden the respiratory system, causing rapid breathing. Under such stress, the bronchi may fail to cope, potentially leading to asthma symptoms. If symptoms persist without improvement, patients may require oxygen therapy at a qualified medical facility.

If symptoms are severe, patients are advised to seek timely medical attention to avoid delays in treatment. During the treatment period, strenuous physical activities should be avoided.
