In one exceptional case that left scientists with no answers, three Australian children developed antibodies to counter COVID-19 but never tested positive for the disease. Although a little over a year has passed since China’s discovery of the new coronavirus, SARS-CoV-2 that causes COVID-19, researchers have found the case of six-, seven-, and nine-year-olds so peculiar that they studied that specific family and published the results in the journal Nature entitled “Immune responses to SARS-CoV-2 in three children of parents with symptomatic COVID-19”.
A couple in Australia, Leila Sawenko and Tony Maguire, contracted the virus in March 2020 and suspected it had been transmitted while they were traveling interstate to attend a friend’s wedding. Since testing positive for the disease raised concerns about the safety of their three children, the parents chose to test the children as well. However, all three results were negative even though they were very close to their COVID-19 positive parents.

According to the study, two children showed mild symptoms but one of them remained completely asymptomatic. Later another test was done only to get negative results. According to reports, this went on for a number of weeks, but what caught the doctors’ attention was that the children had not tested positive for COVID-19 but polymerase chain reaction (PCR) tests. of the children showed antibodies to SARS-CoV-2.
Therefore, the study states: “These data indicate that children can activate an immune response to SARS-CoV-2 without virological confirmation of the infection, increasing the possibility that immunity in children may prevent the onset of SARS infection. CoV-2. Relying on routine virological and serological testing may fail to identify exposed children, with implications for epidemiological and clinical studies throughout life. “
