Sero-Survey begins in New Delhi to determine the Spread of COVID-19

As a part of one of the five aspects of the revised COVID-19 response plan of New Delhi, the Delhi Government jointly with National Centre for Disease Control will conduct the Sero Survey across the National Capital from 27th June 2020.

Amidst a rising number of COVID-19 cases over the last one month, the Survey will help in determining the extent of spread of the Coronavirus disease in New Delhi. 20,000 residents will be covered under the Survey from all the 11 districts of New Delhi.

About the Sero-Survey

ELISA (Enzyme-linked immunosorbent assay) based antibody kit developed by the National Institute of Virology (NIV) will be used for the Survey. A pilot Sero Survey was conducted in New Delhi by using the antibody kit earlier in the month. Good results were yielded during the pilot Survey by using the anti-body Kit. The antibody kit of NIV is known by the name ‘COVID Kavach ELISA’.

A Sero Survey is for determining the presence of antibodies in the blood sample of an individual. The presence of the COVID-19 Immunoglobulin G (IgG) antibody in the blood sample of an individual will suggest past exposure to the COVID-19 virus.

Immunoglobulin G (IgG) Antibody

The immune system develops the antibody Immunoglobulin G (IgG) in the blood and other body fluids for protection against bacterial and viral infections. The antibody IgG develops in 7 to 12 days after an infection or immunization.
