Virologist says blood tests can detect share of Thai population infected

A distinguished Thai virologist says blood tests must be used to find out the proportion of the population that has been contaminated with Covid-19. According to a Nation Thailand report, Dr Yong Poovorawan says a blood check can even detect Covid-19 in asymptomatic patients. The head of the Centre of Excellence in Clinical Virology made the assertion in a publish on his Facebook page yesterday.
Yong explains that Covid infections behave like a pyramid, with 90% of sufferers at the bottom – meaning they are asymptomatic or have only delicate symptoms. This is particularly the case with the now-dominant Omicron variant. However, at the high of the pyramid, are the Covid patients who are severely sick with the virus. These embrace the elderly and people with underlying health conditions.
According to Yong, a recent research tested the blood of 80 children between the ages of 5 and 11, who were not in a high-risk group and who showed no signs of Covid-19 an infection. The exams showed that 5 of the youngsters had been contaminated however were asymptomatic, having developed pure immunity to the Covid virus spike protein.
Yong says such immunity can’t be replicated by vaccines and that the children are part of a segment of the population that is still asymptomatic, which means they need to take a blood check to indicate they’ve been contaminated with the virus. Concealed are the only method to accurately determine how many people within the country have been contaminated with Covid-19 and gone on to develop pure immunity.
However, he provides that such immunity doesn’t final lengthy, dropping to 25% a 12 months after infection. According to the virologist, blood exams can be used in conjunction with a person’s vaccination history to determine immunity levels.
