The sero survey carried out in five zones in Pune has found 51.5% seroprevalence, with the spread ranging from 36.1% in the lower bound to 65.4% in higher bound. The spread of the virus was found across all types of dwellings. @MenonBioPhysics @epigiri @GKangInd
Those living in hutments (62%) and tenement (56.2%) had the highest seroprevalence, while those living in bungalows (43.9%) and apartment (33.2%) had the lowest seroprevalence.
While the seropositivity was 45.3% among the people (1,045 adults) who have access to independent toilets, 619 adults who share toilets have a high 62.2% seroprevalence.
Those in the age group 51-65 years had the highest seroprevalence of 54.8%. Those in the age group 18-30 years and 31-50 had seroprevalence of 52.5% and 52.1%, respectively. Surprisingly, older people (above 66 years) had lower prevalence (39.8%)
The THSTI-RBD-ELISA assay, which has 100% specificity and 84.7% sensitivity was used for testing the samples. The assay has been extensively characterised and compared with other commercially available tests for SARS-CoV-2 IgG.
The survey was carried out by scientists and epidemiologists from Savitribai Phule Pune University, Indian Institute of Science Education and Research (IISER) Pune, Translational Health Science and Technology Institute (THSTI), and Christian Medical College (CMC), Vellore.
The details of the survey have been posted on Savitribai Phule Pune University website http://cms.unipune.ac.in/~bspujari/Covid19/Pune2/
