At the State stage, it was estimated that there have been 40 undetected contaminated people for each RT-PCR confirmed case, i.e., case-to-undetected-infections ratio (CIR) of 1:40. The cases-to-infections ratio ranged from 10 to 111 throughout models. In the nationwide sero prevalence survey performed by ICMR, the CIR was 81.6 to 130.1 in the primary spherical (May), which improved by the second spherical to 26–32 infections per case.
