New Delhi | Jagran News Desk: The Union Health Ministry on Tuesday said that on an average the prevalence of IgG antibodies in the national capital is recorded at 23.48 per cent. The results came out after the Sero Survey conducted by the National Center for Disease Control (NCDC).

The results also showed that a considerable number of infected persons in Delhi remains to be asymptomatic. The study was conducted from June 27, 2020, to July 10, 2020.

“A total of 21,387 samples were collected as per lab standards and were tested. The tests done help in identification of the presence of antibodies in the general population. These test performed is not a diagnostic test but only provides information about past infection due to SARS-CoV-2 in individuals who test positive”, the government statement said.

The tests help in the identification of the presence of antibodies in the general population. The test performed is not a diagnostic test but only provides information about past infection due to SARS-CoV-2 in individuals who test positive, the ministry said.

For all the 11 districts of Delhi, survey teams were formed. Blood samples were collected from selected individuals after taking written informed consent and then their sera were tested for IgG antibodies and infection using COVID KAVACH ELISA approved by Indian Council for Medical Research (ICMR).

It is one of the largest sero-prevalence studies conducted in the country using the ELISA testing. Notably, the study also indicates that a large number of infected persons remain asymptomatic. This implies the following:

1. Nearly six months into the epidemic, only 23.48 per cent of the people are affected in Delhi, which has several pockets of dense population. This can be attributed to the proactive efforts taken by the Government to prevent the spread of infection including prompt lockdown, effective containment and surveillance measures, including contact tracing and tracking, as well as citizen's compliance to COVID Appropriate Behaviours.

2. However, a significant proportion of the population is still vulnerable. Therefore, containment measures need to continue with the same rigour. Non-pharmacological interventions such as physical distancing, use of face mask/cover, hand hygiene, cough etiquette and avoidance of crowded places, must be followed strictly.

A sero-survey involves testing of blood serum of individuals to check for the prevalence of antibodies against the infection.
