Over a half of coronavirus infections revealed this summer by one of Belgium’s biggest labs were old and no longer contagious, but were still reported as new cases, local media discovered.
Belgian daily newspaper Het Laatste Nieuws examined the tests carried out by AZ Delta, one of the largest labs in the country, and made a stunning discovery. Almost half of all positive cases reported throughout June, July and August were actually people with an old infection.
The problem, it turns out, lies in the PCR Covid-19 tests. The paper reports that scientific data reveals virus particles can be detected up to 83 days after the actual infection. This led to instances where people were no longer contagious, but were still registered as positive cases. According to HLN, all of these people had to be quarantined.
“We may have had to deal with old infections largely in the summer months,” the lab’s clinical biologist Frederik Van Hoecke told the paper.
The revelation comes as an increase in positive tests sparks fears of a second wave, as countries look to reintroduce restrictions to curb the spread of the virus.
