The novel coronavirus is a β-genus coronavirus. Its internal structure is a single strand of positive-strand RNA virus. It has an envelope on the surface and protrudes on the outside of the envelope.

Its envelope can be round or oval, and its shape is pleomorphic. Because the virus has protrusions on the surface, it looks like a crown, so it is called the new coronavirus.

The diameter of the entire virus is 40-160nm. There are three types of surface proteins of the virus, namely S protein, and also small-encapsular glycoprotein and membrane glycoprotein. This small-encapsular glycoprotein is called E protein, membrane protein is called M protein, and a few types also include hemagglutinin glycoprotein, also called HE protein.

S protein is used to bind to the surface receptors of the host cell, and fuses with the envelope of the conduction virus with the envelope of human cells. The M protein participates in the formation and budding of virus envelope . The HE protein is the short protrusion that constitutes the envelope, which is related to the early adsorption of the virus.

The difference between cold symptoms and novel coronavirus pneumonia

First, cold patients are very rare in fever, while novel coronavirus pneumonia is very common, often mainly low fever, and high fever occurs after progressive aggravation in 3-5 days.

Second, headaches in patients with colds are very rare, while headaches in patients with new coronary pneumonia are more common, and mild systemic pain in patients with colds is very common in patients with new coronary pneumonia.

, cold patients sometimes feel tired or weak, while COVID-19 patients often feel tired, weak and weak in their limbs.

Fourth, other symptoms include common colds and nasal congestion, while new coronary pneumonia is rare. Sneezing and sore throats in patients with colds are common, while new pneumonia is rare, so clinical symptoms should be identified according to the specific situation.

Automatic reports of new coronavirus infection: Although the disease has been cured, it is troubled by "sewages".

What should I do if I get infected with the new coronavirus?

. First of all, we must not panic. If you are outside, call 120 emergency number immediately. Do not go to crowded places, wear masks, and keep at least 1.5 meters away from people. Wait for medical staff to come and pick you up to the hospital;

. If you are at home and live alone, you need to self-isolate, wait for relevant medical staff to contact, do not go out, do not go with family and friends. Contact, prepare your own personal supplies for hospitalization;

. If you live with your family, you need to wear a mask and isolate it in a room. Let your family help prepare the items needed for hospitalization and wait for medical staff from the disease control department to come to the door;

. If you are in the company, report to the leader as soon as possible, and isolate it separately. Wear a mask. Do not touch the surrounding environment and wait for the disease control personnel to pick you up to the hospital.
