There have been several waves in a year, and if you are infected, you can get infected again… Could the new coronavirus become like this?
A study published in the journal Science showed that the reinfection rate of the Omicron strain was significantly higher than that of the previous beta and delta strains .
And, even if you have been infected with other new coronavirus strains before, it is possible to infect Omicron again and again.
The study used South African epidemiological data to identify and analyze more than 100,000 cases of multiple infections from the data of 2 million people infected with Covid-19.
Among them, many were infected three times, and then infected with Omicron again after being infected with the original strain, the delta strain.
A news published in Nature also said that so far, 650,000 people in the UK have been re-infected with the new crown, the vast majority of whom were infected by Ormick in December last year. It has happened since Rong appeared.
Until November 2021, less than 1% of confirmed cases in the UK will be reinfections. After the emergence of Omicron, the proportion of repeated infections increased significantly, and the difference was about 10 times compared with the early stage of the epidemic.
Omicron’s pattern of transmission appears to be more and more like the common cold: there is no clear seasonality, variation is fairly rapid, and multiple infections can occur in a short period of time.
In this case, herd immunity is not realistic to completely avoid infection, and vaccines need to be updated as soon as possible to deal with new mutant strains.
While it’s hard to say anything about a study, it can at least provide some guidance on how we can prevent the spread of the virus.
