December 7, 2022 Prof.Dr. Yong Poovorawan or “Mo Yong” Head of the Center of Excellence in Clinical Virology Department of Pediatrics Faculty of Medicine Chulalongkorn University Post messages via Facebook page. Yong Poovorawan indicate that COVID-19 60 to 70 percent of the Thai population has been infected.
Prof. Yong Phuwarawan or “Mo Yong” further revealed that from the study of the Center of Excellence in Clinical Virology, Chulalongkorn University, 2 projects, the first project being a study inChildren 5-6 years old in the past year with blood tests 2 times, 1 year apart, about 190 people, it was found that during the last year orDelta era About 10 percent of children this age in Bangkok have already been infected (2021).
But when it comes to this year (2022) it comes to this month. It was found that the infection has soared to between 60 and 70 percent of all children. And of these, 35% were asymptomatic infections. or do not know if there is an infection From the history taking, it is unknown if there was an infection. But blood tests revealed evidence of infection. Shows that there are many children who have already been infected. asymptomatic type and did not know that there had been an infection
At the same time, the study together with the provinceChonburi Perform blood tests from 6 months to 80 years. At present, approximately 700 people have been examined and found that they have already been infected from the evidence of the blood tests. and history of infection It’s about 60-70 percent. Evidence of blood tests. if infected for a long time especially infected for more than a year may result in negative results Most infections occurred this year. during the outbreak with omikron strains
when detecting antibodies produced by infection or from vaccines It will be found that approximately 95 percent of the population has some detectable immunity. Especially at this time it is not possible to tell how high the level of immunity is. to prevent or reduce the severity of the disease Almost the majority of the population has been exposed to or known to COVID-19. from infection or already vaccinated This is one reason why the severity of the disease is reduced.
already infected or get vaccinated Able to measure immunity can be re-infected Therefore, we are constantly seeing an increase in the number of second-time infections. on the basis of the immune system A second infection is likely to reduce the severity of the disease. However, it also depends on the condition of the body at that time.
when there is a re-infection can be again There is reason enough for people who have completed 3 or more vaccinations and have been vaccinated for a long time. or have been infected before And after a long period of time, such as more than 6 months, they can receive a booster vaccine to train the immune system to recognize prevention and reduce the severity of the disease.
each vaccine The efficacy in reducing the severity of the disease was not different. depending on the number of times given and prevention and reduction of violence It will be good after the injection in the first months and the landscape will decrease over time.
givingstimulator needleshould be spaced from the last In principle, the farther the better. Or wait for the immunity to decrease first and then stimulate. But at the same time, if it is too long, it will cause infection first. The time it takes for a person who has received 3 or 4 doses or is infected to receive stimulation should be 6 months or more. will stimulate a high level of immunity In the risk group, it can be stimulated 1-2 months earlier, it can be done.
