What are the early symptoms of novel coronavirus infection? What obvious changes will happen to the body?

Novel coronavirus's early symptoms will be like a cold, mainly physical abnormalities, fatigue, muscle aches, and some patients will have symptoms such as intestinal reaction, diarrhea and abdominal pain. Later, with the development of the disease, the patient will have a fever, and there will be obvious symptoms in the respiratory tract, that is, dry cough, and then there will be more serious symptoms such as dyspnea, chest tightness and suffocation. During the test, patients will find lung lesions. Some patients will also have headaches, which is also due to the phenomenon of brain hypoxia caused by respiratory hormones, and some patients will also have olfactory and taste disorders, which is also a special symptom.

There are three modes of transmission of novel coronavirus infection. One is direct contact, especially with some infected patients. Talking droplets or exhaled gas can cause infection after close contact, and the other is contact transmission. For example, droplets sprayed by patients accumulate on the surface of objects, which will infect healthy people after contact. For example, these viruses will stay on doorknobs and fruits. At the same time, there is the diffusion of aerosol. Fog droplets mixed in the air will form aerosol, which will cause infection once inhaled by human body.

At present, what we can do for COVID-19 is to vaccinate COVID-19 vaccine in time to prevent it. We should keep indoor air circulating at ordinary times, but we should also pay attention to avoid staying in some places where the air is not circulating. If we go out, we must wear masks. Wash your hands and disinfect your clothes when you get home. If you have symptoms of fever and respiratory infection in your life, you must go to the hospital in time.

Finally, COVID-19 is highly contagious. Now many people have asymptomatic infections, which does not mean that patients will not be contagious, so prevention is still very important.
