By stating that “reinfection of the “Omicron” strain in the same person within 1 month is a concern or not? Understanding the re-infection of “Covid-19”
more
Q1: Repeated coronavirus infection 2019 within 1 month and caught during this period. (February-March 2022) Are you worried? Why?
A1: The answer is “worrying” because the epidemic during this period in Thailand and the world is a transition period from omikron subspecies BA.1 to BA.2. The WHO still classifies BA.1 and BA.2 is just a subspecies of Omikron. and give advice on prevention, care and treatment of BA.1 and BA.2 that are not different
Q2: Has anyone been found infected with Omikron BA.1 and then, within the next 20-60 days, there was a re-infection? How many (reinfection) are there?
A2: A study of re-infections in the Danish population between November 22, 2021 and February 11, 2022, out of 1,848,466 infected people, was found to be re-infected with whole-genome transcription. Of the 187 BA.2 cases, of which only 47 were genetically proven to be infected with BA.1 first and followed by re-infection with BA.2 between 20-60 days.
In conclusion
Out of the 1.8 million people infected, 47 had been infected with BA1 before, and then 47 were re-infected with BA.2, and 1,848,419 were infected, most of them were unvaccinated children. It is approximately the ratio of “1 in 40,000” of those who have been infected with BA.1 and have been infected with BA.2 once more. https://www.medrxiv.org/…/2022.02.19.22271112v1.full.pdf
Q3: Why does WHO still classify BA.1 and BA.2 as the only subspecies in the main omikron? and give advice on prevention, care and treatment of BA.1 and BA.2 that are not different despite having found a re-infected
A3: Because of the information WHO has received from around the world, it can be concluded that re-infection from “BA.1 and then re-infected with BA.2” can occur, but is rarely found. (Danish population, 1 in 40,000), coupled with re-infected BA.2, no symptoms so severe that hospitalization or death This means that the immunity obtained from the natural “BA.1” infection is still able to protect once morest infection. prevent serious illness and preventing death from BA.2 well, although not 100% This means that vaccination will help prevent re-infection.
Q4: Is BA.2 infected for the first time and then re-infected with BA.1 or those strains that have been previously epidemic such as Delta?
A4: According to a study of re-infections in the Danish population between 22 Nov 2021-11 Feb 2022, out of 1.8 million infected people, the first BA.2 infection has not yet been re-infected. BA.1 or those strains that have been re-infected before It can be concluded that natural immunity once morest BA.2 infection would be highly protective once morest BA.1 infections and previously disseminated strains.”
