COVID-19 infection in 2019 was caused by lung inflammation. Coronavirus is a large class of viruses widely existing in nature, which belongs to the coronaviridae of the order Nidovirales.
The classification of virus mainly includes the following ways: 1. Classification according to genetic material. It can be divided into DNA virus and RNA virus. Most viruses are DNA viruses; a few are RNA, including coronavirus (SARS virus), HIV, tobacco mosaic virus and influenza virus. This year's novel coronavirus is a recently discovered coronavirus. 2. According to different infected objects, it can be divided into plant virus, animal virus, bacterial virus, etc.
The composition of the virus as a whole is very simple, mainly including protein coat and genetic material. There is no life feature in nature, only in the host body, can we achieve self proliferation.
The process of virus proliferation includes adsorption, injection, synthesis, assembly and release. In the process of virus proliferation, a large number of substances from the host are used to synthesize their own genetic materials and proteins. When the offspring virus is released, the host cell will rupture and die.
The novel coronavirus pneumonia is parasitic in the respiratory system of the human body. When the virus is propagated in large numbers, it will cause massive death of alveoli, thereby causing adult suffocation. It's also because it lives in the respiratory system, so it can be spread through droplets, which is why we wear masks.
Viruses exist widely in nature, some of which are known to us and some of which are unknown to us. As long as there is no pandemic, the existence of the virus is in a balance. Once the balance is reached, it will cause a pandemic, so it is very important not to eat wild animals. The balance in animals is easy to cause imbalance after entering the human body, such as AIDS.
