More than 50 percent of the pediatric population in Mumbai healthcare facilities has antibodies to Covid-19, according to a sero survey prior to the third wave.

In addition, the proportion of the pediatric population with antibodies has been shown to increase compared to previous sero-surveys conducted during the first wave and the second wave.

The sero-study for SARS-CoV-2 infection among the pediatric population of Mumbai was conducted by BYL Nair Hospital and Kasturba Molecular Diagnostic Laboratory, both run by the BrihanMumbai Municipal Corporation (BMC).

As the third wave is expected to affect children, Municipal Commissioner Iqbal Singh Chahal and Additional Municipal Commissioner (Western Suburbs) Suresh Kakani have commissioned a sero-test on children during the second wave itself – and accordingly it performed from April 1 to April 15. June.
