New Crown XE refers to a new neocoronavirus mutant strain that is a recombinant variant of two omicron sub-strains. New Crown XE belongs to a recombinant variant type of neocoronavirus mutant strain, formed by mixing two strains of omicron BA.1 and omicron BA.2. Currently, the early growth rate of XE is not significantly different from that of BA.2, but the growth rate and transmission rate of XE is higher than that of BA.2, and the X strain is more infectious than the BA.2 strain. If you want to prevent the infection of Neo-Crown XE, it is recommended to take precautionary measures, such as wearing a mask when going out and avoiding crowded public places. Secondly, you should get vaccinated against the new coronavirus by replenishing your body’s antibodies to minimize the chance of contracting the new coronavirus. If you have symptoms such as fever or cough, you should suspect whether you are infected with the new coronavirus or the new coronavirus XE, and then you should go to the hospital as soon as possible for nucleic acid testing to determine whether you are infected.
