Explanation of coronavirus terms

Novel coronavirus is an RNA virus, belonging to a large family of coronaviruses.

With the outbreak of Wuhan epidemic, we began to pay attention to this coronavirus that has never been found in humans before. Since the outbreak of 20 19, WHO named it novel coronavirus (20 19-nCoV), and the disease it caused was named 20 19 coronavirus disease (coronavirus pneumonia-19, that is, coronavirus disease 20 19).

Structure:

Novel coronavirus is an RNA virus with envelope and linear single-stranded positive genome. Its particles are round or oval, with a diameter of about 60- 140nm, which can directly guide cells to synthesize the required protein, so as to rapidly replicate and strengthen its spread.

COVID-19 protein capsid consists of spike glycoprotein (S), hemagglutinin-esterase (HE), membrane glycoprotein (M), envelope protein (E) and nucleocapsid,

Transmission path:

Mainly respiratory droplet transmission and contact transmission.

Coronavirus is a very large virus category, which contains many kinds and can cause many diseases. After infection, the symptoms of patients can range from the common cold to severe lung infection, such as Middle East respiratory syndrome and severe acute respiratory syndrome.

The novel coronavirus found in Wuhan this time is a kind of novel coronavirus that has not been found in humans before.

This time, novel coronavirus infection is very common among people, causing outbreaks and epidemics in many parts of the country, and people are generally susceptible. After infection, some patients will develop respiratory failure and even lead to death.
