Because Ms. Yin did not go to the designated fever clinic after she developed symptoms, she chose two general medical institutions, which led to the infection of medical staff. One of them is Dr. Cai Chao who went to study. Medical staff have to contact different patients every day, and the probability of contracting various diseases is much higher than that of ordinary people. It's all the result of infection caused by carelessness. After Ms. Yin returned to China, her nucleic acid test was negative, and she was isolated for 14 days. She thought she was safe, but the cunning virus escaped the incubation period of 14 days before it started to act, which caused Ms. Yin not to think that she was infected.
How this doctor infected COVID-19 is not clear, but it is also because he is in the same hospital. Because several infected people are infusion patients in the same ward as Ms. Yin, and then there are close contacts of these infected people. COVID-19 virus is transmitted by respiratory droplets. If the patient does not wear a mask correctly, or touches some public goods with contaminated hands, it may infect others.
What should we do to prevent COVID-19 infection? After infecting humans, COVID-19 used human cells to reproduce, and then infected new hosts, so as to survive and develop. While human beings are fighting against viruses, viruses will also change. Therefore, when preventing COVID-19 infection, we should not take it lightly, but be vigilant.
First of all, try not to go to crowded places and reduce crowds and parties, which can effectively reduce the chances of close contact. Wear a mask correctly. The mask needs a medical surgical mask. Wear it correctly, and it can't leak out of the nose or leave a big gap. Ordinary cotton masks can't stop the virus. Keep a social distance of more than one meter when talking with people. Cover your nose and mouth when coughing or sneezing to reduce the spread of droplets.
Secondly, wash your hands frequently, ventilate more, and increase air circulation. Washing hands frequently can reduce the chance of contaminated hands touching nose, mouth and eyes. , or further pollute other items. Virus infection also needs a certain concentration, and increasing air circulation can reduce the density of possible viruses.
There is also diligent disinfection, disinfectants and ultraviolet rays are effective for coronavirus. Ultraviolet rays, 75% alcohol and chlorine-containing preparations can be used to disinfect the surface and environment of articles regularly.
If you find suspected symptoms such as fever and sore throat, you must go to the designated fever clinic.
In a word, we can't treat COVID-19 lightly. We must strengthen our precautions and try our best to reduce going out. If you go out, be sure to wear a mask and wash your hands frequently. While protecting yourself, you are also protecting your family.
