Virologist says blood tests can detect proportion of Thai inhabitants infected

A outstanding Thai virologist says blood checks must be used to determine the share of the inhabitants that has been contaminated with Covid-19. According to a Nation Thailand report, Dr Yong Poovorawan says a blood take a look at can even detect Covid-19 in asymptomatic patients. The head of the Centre of Excellence in Clinical Virology made the statement in a post on his Facebook page yesterday.

According to Yong, a current research examined the blood of eighty children between the ages of 5 and 11, who weren’t in a high-risk group and who confirmed no indicators of Covid-19 infection. The tests confirmed that 5 of the kids had been contaminated but have been 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 a part of a segment of the population that continues to be asymptomatic, that means they need to take a blood take a look at to point out they’ve been contaminated with the virus. This means blood exams are the only approach to accurately determine how many individuals in the nation have been contaminated with Covid-19 and gone on to develop natural immunity.
However, โซล่าเซลล์ราคาถูกคุณภาพดี adds that such immunity doesn’t final lengthy, dropping to 25% a yr after infection. According to the virologist, blood tests can be used in conjunction with a person’s vaccination history to discover out immunity levels.
