COVID-19 virus The new strain EG.5 has now become the strain causing the most new cases in the US, surpassing the former champion XBB.
Foreign news agencies reported on August 9, 2023 that the COVID-19 virus The new subspecies EG.5 has already become the strain that causes the most new cases in the United States, accounting for about 17% of all new cases in the country. This surpassed the XBB.1.16 strain that caused approximately 16% of cases.
EG.5 is a branched subspecies of the XBB family, which emerged from the Omicron family. And there are only a few mutations. Doesn’t evolve at a leap like Omicron
According to the disclosure of The US Centers for Disease Control and Prevention EG.5 has only one additional mutation at genotype number 465 on spiny proteins compared to its parent strain, XBB.1.9.2, and this mutation has previously been shown. seen in the covid-19 virus Other species ago
The mutation at gene position 465 is found in the genotype of the COVID-19 virus in approximately 35% of all reported strains worldwide. Including another strain that is becoming more widespread in the northeastern United States, FL.1.5.1, indicating that the mutation at this location has some evolutionary advantages over its predecessor.
EG.5 already has its own subspecies, called EG.5.1, with the addition of a second mutation at the spiny protein. and is spreading rapidly
Besides the United States, EG.5 is spreading rapidly in Ireland, France, the United Kingdom, Japan and China. The World Health Organization upgrades its status from an under-observed strain of the virus. It is a strain of virus that has received attention. which is a signal that They think that EG.5 should be monitored and studied further.
EG.5 has become the most common strain of COVID in the US. during the same period Number of patients, who need to go to the emergency room and hospitalization due to COVID-19 has increased, but so far there is no indication that EG.5 is a contributing factor to the increase.
