New Delhi: The National Centre for Disease Control (NCDC) Saturday began carrying out a serological survey to ascertain the spread of Covid-19 in the national capital. Serological tests are used to check whether a person has antibodies, which are naturally occurring proteins produced by the body’s immune system to fight off infection.
While a serological test cannot determine whether someone currently has coronavirus, it helps to ascertain whether they were recently exposed to the virus.
On the first day of the serological survey in Delhi, teams of health workers knocked on random houses in different areas and collected blood samples of residents, irrespective of their gender and age.
ThePrint’s photojournalist Manisha Mondal visited the Ramnagar area of Paharganj in the national capital to bring you glimpses of how the survey is being carried out.
