At present, the global new coronavirus is not over. The strains prevalent in different countries may be different. For example, the currently popular strains in my country are Omicron mutant strains ba.5.2 and bf.7. However, the strains prevalent in the north and south will be different. Beijing is BF.7, and Guangzhou is BA.5 and BA.5.2.
Winter is a period of high incidence of new coronavirus infections, so my country is letting go of the epidemic at this time. There are voices of doubt, but there are also voices of approval. But after the epidemic was lifted, the number of positive patients was increasing. According to the epidemic situation reported by other countries, the number of confirmed cases is increasing every day, and there are also many deaths.
Previously, the restart of COVID-19 testing in the United States has attracted a lot of attention, because the current COVID-19 virus in the United States is also at its peak. According to the latest news, the According to the infection rate in the United States in the past week, the infection rate has doubled.
As XBB.1.5 became popular in the United States, people in our country were more concerned about what medicines they needed to prepare, so this was the reason why montmorillonite powder was out of stock overnight. Is the
XBB strain available in China? The
XBB strain is not currently available in China, but it may be introduced into our country in the future.. But there is no certainty about how long it will take. I remember that when the Omicron variant was popular abroad, it didn't take long for it to begin to be introduced into our country. As of December 31, 2022, XBB.1.5 has been found in at least 74 countries and regions, and it has spread to 43 states in the United States.
Now that overseas import policies have been adjusted, it is very possible for the XBB strain to reach China, and everyone should still pay attention to protection. What are the symptoms of
XBB.1.5 infection?
Symptoms of infection with XBB subtype strains include difficulty breathing, headache, sore throat, nasal congestion, body aches, fatigue and fever. Data posted on Twitter by Cao Yunlong, an associate researcher at Peking University's Biomedical Frontier Innovation Center (BIOPIC), also showed that XBB.1.5 is not only as effective at evading antibody protection as the XBB.1 variant, but the former has a high degree of immune evasion and is better at binding to human cells through key receptors.
The increase in mutated strains such as the Omicron subtype strain Vaccine, if a breakthrough infection occurs in the elderly, they need to receive treatment with the antiviral drug Paxlovid.
In short, XBB.1.5 has become the most prevalent strain in the United States, but it is not yet available in China. However, XBB.1.5 has been found in at least 74 countries and regions. This virus requires more attention and caution for the elderly.
