1. Where did Delta go after Omicron arrived
Researchers monitored wastewater in the southern Israeli city of Beersheba from December 2021 to January 2022, and found that as the Omicron strain accelerated its spread, the Delta strain did not disappear, but It is still spreading covertly.
2. The difference between Omicron and Delta
1 The main differences between COVID-19 Delta and Omicron are the different mutation points, different infectivity, and different pathogenicity.
2. New Crown Delta contains 15 spike protein mutations, while Omicron contains 32 spike protein mutations, one more than New Crown Delta. More than times. These spike mutations make Omicron more contagious.
3. Through research on viruses, it has been found that Omicron is more transmissible than COVID-19 Delta and spreads faster. It will cause infection in a short period of time. Large numbers of people are infected.
4. The toxicity of the two is also different. Through study of cases, it was found that Omicron is less toxic than COVID-19 Delta. Omicron mainly infects the upper respiratory tract, exhibits flu-like symptoms and recovers relatively quickly, while COVID-19 Delta mainly infects the lower respiratory tract, so the condition is relatively severe.
5. The result of the continuous mutation of the virus is that the virus is more transmissible, less toxic, and more suitable for long-term survival. Therefore, the new coronavirus continues to mutate and is developing in the direction of influenza.
3. When did Delta appear
1. Delta virus first appeared It was first discovered in India in August 2020. In May this year, the World Health Organization named it Delta. In other words, this virus began to spread in India in August last year and was gradually imported to all parts of the world. Country.
2. Currently, my country still implements a dynamic clearing policy for the virus.
4. The relationship between Omicron and Delta
1. Omicron and Delta are both mutations of the new coronavirus There is no direct link in toxicity between the two strains.
2. To some extent, Omicron is more toxic than Delta. It is highly contagious and easier to combine with the human body. Because of this, Omicron may spread to humans at a faster rate and is more diffusible.
5. Triggering conditions for Delta disease strain
The triggering condition for Delta disease strain is that both people Triggered by close contact without protective measures, the \”Delta\” mutant strain is the most transmissible variant discovered so far. It has appeared in at least 85 countries and regions and is spreading rapidly among unvaccinated people.
6. Comparison of the propagation speed of Omic velvet and Delta
WHO stated that in countries and regions with community transmission, the Omicron strain spreads significantly faster than the Delta strain, with a doubling time of between 1.5 and 3 days. Countries with higher levels of immunity are experiencing rapid spread, and it is uncertain to what extent the accelerated spread is related to immune evasion or inherent increased infectivity.
According to Based on the available data, WHO predicts that the Omicron strain is likely to overtake the Delta strain in areas where community transmission is occurring.
