About 20-25 per cent patients cured of COVID-19 have little or no antibodies against coronavirus: AIIMS-Patna
Dr Kumar told a newspaper that the level of IgG was low in those suffering from mild symptoms or asymptomatic cured patients. However, IgG levels spiked in recovered patients with more critical, severe and moderate symptoms.
“Several studies conducted by scientists and researchers also revealed the same in their research,” added Dr Kumar.
“Immune response that produces antibodies to protect against the virus is high in people, who are more infectious to the disease. Secondly, some people have recovered before the ideal time (28 days) for the development of antibody after cessation of symptoms. Lastly, the IgG level depends on the immune system of individuals. So, the cured asymptomatic and mild symptoms patients need to be careful, because of chances of reinfection,” he said as he underlined three possible reasons behind the difference in antibody level observed in cured patients.
