Virus is a kind of non cellular organism. What is a cell? Cell is the basic unit of human body and physiological function. The virus is a kind of organism that invades the human body. It is a parasite in the microbial world. The virus can not reproduce itself, but can only parasitize in other cells and absorb nutrition to survive and reproduce. Therefore, it is not easy to find the virus in the early stage, which is called the incubation period in the medical field.
Novel coronavirus can cause pneumonia. The infected person will have incubation period for 14 to 15 days, and it will be short to two or three days. After the latent period, people will have a fever, cough, dizziness, and difficulty breathing. Go to the hospital for treatment.
In the hospital, the angels in white are treating the infected people at the front line. They are wearing protective clothing, gloves, hats, masks and goggles. In the scientific research institute, scientists are working day and night to develop antibodies to eliminate these viruses; in the factory, workers are working overtime to make masks and protective clothing, so this war is not only for angels in white, but also for every Chinese. The virus is not invincible. As long as we work together, we can win the war without smoke of gunpowder.
Although the virus is severe, it has antibodies against it. Before the antibody is developed, we ordinary people should take safety protection measures and try not to go out, so that the virus can not infect ourselves. When going out, we must wear masks to avoid infection, which is the greatest contribution to this war.
