The Delhi government will begin serological surveillance every month to combat COVID. This is what it means.


Data released by national sero-surveillance by the Indian Council for Medical Research (ICMR) revealed that in June, only 0.73% of the sample population was infected with the deadly COVID-19. The virus has infected 1.19 million people in the country so far, making it the third country most affected by the pandemic.

Serological surveys, conducted over time, could also inform officials of statistical data on any disease. For example, with an infection as terrifying and rapidly spreading as COVID-19, a serological survey could provide information on what percentage of the population in a given city or district may have acquired some form of immunity to the virus. It could also provide input on what additional steps to take, where the disease is most concentrated, or age groups that may be most at risk.

Therefore, serological surveys carried out over a period of time, or carried out every month, as well as what has been detailed, can be one of the ways to measure the spread of the disease or map the consequent peaks of the infection.
