Introduction
In general, novel coronavirus infection is caused by the novel coronavirus. It is important to practice personal protection in daily life, wear masks properly when going out, and avoid crowded places. Wash hands frequently, maintain indoor ventilation, and reduce the risk of virus transmission. Keep a regular作息 (routine), eat a balanced diet, and consume more foods rich in protein and vitamins.

Generally, novel coronavirus infection is caused by the novel coronavirus. The specific analysis is as follows:

Novel coronavirus infection is caused by the novel coronavirus, which belongs to the β genus of coronaviruses and has strong transmissibility. After entering the human body via respiratory droplets and other routes, the virus binds to ACE2 receptors on the surface of respiratory epithelial cells, invades the cells, replicates extensively inside them, and disrupts normal cellular functions. Newly replicated viruses are then released outside the cells, infecting neighboring cells and triggering an immune response in the body, leading to a series of infection symptoms such as fever, cough, and fatigue. In severe cases, it may damage the lungs and other organs.

Daily personal protection is essential. Wear masks properly when going out and avoid crowded places. Wash hands frequently, ensure indoor ventilation, and reduce the risk of virus transmission. Maintain regular作息 (sleep-wake cycles), eat a balanced diet, and consume more foods rich in protein and vitamins to strengthen the body's resistance. If suspicious symptoms occur, promptly isolate yourself and seek medical attention at a qualified healthcare facility to prevent further spread of the virus.
