This year, the world is facing huge difficulties and challenges because we encountered the new coronavirus. This virus has been discovered for the first time. It has strong variability and transmissibility. It has spread around the world. The cumulative number of confirmed COVID-19 patients has reached more than 20 million, and the cumulative number of deaths has reached 810,000. The situation seems to be getting more and more serious, and the virus strain has even mutated, and the development of a vaccine is also urgent. On August 21, WHO held a regular press conference on COVID-19, and the Director-General of WHO delivered a speech. 1. Mutations do not affect infectivity
The WHO Ministry of Health stated that there are currently more than 80,000 new coronavirus genetic sequences in the world, and most mutations will not affect the infectivity and severity of the virus. WHO has set up a dedicated working group to identify different mutations and study their possible impact on the behavior of the virus. We hope that the COVID-19 pandemic can be ended within two years by making full use of anti-epidemic tools, including vaccines. 2. What is a gene sequence?
So what exactly is a gene sequence? A gene sequence is a string of letters representing the real or hypothetical primary structure of a DNA molecule that carries genetic information. Part of the DNA sequence or gene sequence uses a string of letters to represent the real or hypothetical primary structure of the DNA molecule carrying genetic information. A string of nucleotides with any length greater than 4 is called a sequence. 3. Self-protection before the epidemic
Russia is the first country in the world to officially register the new crown vaccine. However, according to surveys, only 40% of the Russian people are ready to receive the domestically produced new crown vaccine, and there are actually 40% who do not plan to receive it. Accounting for 50%, the Russian people are still worried about the safety of the new crown vaccine. Therefore, when the safety of vaccines has not been fully guaranteed, we should protect ourselves even more. Try not to go to crowded places; wear a mask when going out, and develop the habit of washing hands frequently, checking body temperature frequently, and ventilating the house; during home isolation, you should also maintain appropriate exercise to enhance your resistance. By protecting ourselves, we actually contribute to the epidemic.
