Repeated coronavirus infection 2019 within 1 month and caught during this period. (Feb.-Mar.22) Are you worried or not? Why?
The answer is worrying because of the epidemic during this period of Thailand and the world. It is the transition period from omicron subspecies BA.1 to BA.2. The World Health Organization WHO still classifies BA.1 and BA.2 as only subspecies of omicron. and provide advice on prevention, care and treatment that are different
People who are infected with Omikron BA.1 and then within the next 20-60 days will be re-infected or not? how many
A study of re-infections in a population of Denmark between November 22, ’64 and February 11, 65, out of 1,848,466 cases, was re-infected with a complete genome transcription. A total of 187 individuals were found to be infected with BA.2, of which only 47 were genetically identified as having pre-infection with BA.1 and followed by re-infection with BA.2 over a period of 20- 60 days
It was concluded that out of the 1.8 million infected people, 47 had been infected with BA.1 before, and then 47 were re-infected with BA.2. Most of them were children who had not been vaccinated. This 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 again.
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
Because of the information that the WHO has received from around the world, it can be concluded that Re-infection from “BA.1 and then to BA.2” can occur, but is rarely found. In addition, the re-infected BA.2 does not have severe symptoms that require hospitalization. or died This means that the immunity obtained from the natural “BA.1” infection is still able to protect against infection. prevent serious illness and preventing death from BA.2 well, although not 100% This means that vaccination will help prevent re-infection.
Infected with BA.2 and then re-infected with BA.1 or those strains that have been previously epidemic such as Delta?
A study of re-infections in the Danish population between 22 Nov ’21 and ’11 Feb ’65 out of 1.8 million infected people had not been infected with BA for the first time and then re-infected with BA. .1 or those species that have been previously re-infected It was concluded that immunity from natural BA.2 infection would be highly protective against BA.1 infections and previously disseminated strains.
