Latest analysis → Is the "Three Yang" here? Mutant strain EG.5 mutates | virus | triple positive
Recently, the number of cases infected with COVID-19 variant EG. 5 has increased in many parts of the world. The World Health Organization lists EG.5 as a "variant that needs attention.".
"Need attention", COVID-19 mutant EG.5 appears
According to Reuters, the World Health Organization (WHO) announced on the 9th local time that it would list the COVID-19 variant EG. 5 as a "need to pay attention" variant.
It is reported that the World Health Organization (WHO) said on the 9th that it is tracking several COVID-19 variants, including COVID-19 variant EG. 5, which is currently spreading in the United States and Britain.
According to the report, Maria van Kohoff, technical director of COVID-19 of WHO, said that the transmissibility of EG. 5 has increased, but it is not more serious than other Omikjon variants.
According to the report, the World Health Organization has classified virus variants into three categories: "monitored" variants, "noteworthy" variants, and "noteworthy" variants by evaluating their transmission and mutation abilities.
WHO Director General Tedros stated, "The risk of more dangerous variants still exists, which could lead to a sudden increase in cases and deaths."
#People from COVID-19 Sanyang began to appear one after another # board the hot search
Recently, some netizens have expressed that they have become "three yang", and the topic of "three yang" has even become a hot search topic.
Since July, the proportion of patients with severe COVID-19 infection admitted in the infection department of Huashan Hospital has been about 5%, which is mainly concentrated in the first positive, elderly, poor control of basic diseases and people who have not received COVID-19 vaccine. However, in actual patients, there are very few cases of repeated infections and "three positive" cases in the short term, and almost no "four positive" cases.
Wang Xinyu, Deputy Director of the Department of Infectious Diseases at Huashan Hospital affiliated with Fudan University, said: "We are currently in a relatively stable or low period.". Indeed, we have also encountered cases where the infection may occur again in the short term, possibly three months later, but most of these patients have mild symptoms.
What is EG. 5? Where does it spread?

EG. 5 is the "offspring" of the subvariant XBB. 1.9.2 of COVID-19 Omikron, which was first found on February 17 this year.
The way this virus enters cells and tissues in the human body is similar to XBB.1.5 and other Omicron variants. On social media, netizens have named this mutant strain "Iris" according to the Greek alphabet, but this has not been officially recognized by the World Health Organization.
Since the beginning of July, there have been more and more cases of COVID-19 infection caused by EG. 5. On July 19, WHO listed it as a "variant to be monitored".
As of August 7th, 7354 EG.5 gene sequences from 51 countries have been uploaded to the Global Initiative for the Sharing of All Influenza Data, including the United States, South Korea, Japan, Canada, Australia, Singapore, the United Kingdom, France, Portugal, and Spain.
The World Health Organization mentioned EG. 5 and its closely related sub variants, including EG. 5.1, in its latest assessment. According to the British Health and Safety Administration, EG. 5.1 currently accounts for about one seventh of the COVID-19 cases detected by hospitals. The Centers for Disease Control and Prevention in the United States estimates that EG.5 has been prevalent in the United States since April, causing approximately 17% of new infections and surpassing other sub variants of Omicron to become the most common variant. According to the US federal health agency, the number of hospitalizations due to COVID-19 continues to increase throughout the US, with the number of hospitalizations increasing by 12.5% in the recent week to 9056.
Vaccines can still prevent EG.5 infection
EG. 5.1 has two important additional mutations that XBB. 1.9.2 does not have, namely F456L and Q52H, while EG. 5 only has the F456L mutation. The additional minor changes in EG. 5.1, namely the Q52H mutation in the spike protein, give it an advantage in transmission compared to EG. 5.
The good news is that a spokesperson for the Centers for Disease Control and Prevention in the United States stated that currently available treatment methods and vaccines are expected to remain effective against the mutant strain.
According to Reuters, Mandy Cohen, director of the Centers for Disease Control and Prevention in the United States, the updated vaccine in September will provide protection against EG. 5, and the new variant does not represent a significant shift.
The British Health Safety Agency said that vaccination is still the best defensive measure against the COVID-19 epidemic in the future, so it is still very important for people to vaccinate all qualified vaccines as soon as possible.
