The survey was carried out on 15,624 persons in 290 hospitals on persons above the age of 18 across all 30 districts of the state
The survey has found that this number is around 30% in Bengaluru, one of the worst affected regions in the country
Around 27.3% of Karnataka’s over 7 crore population may have been exposed to the covid-19 virus, according to the findings of a sero survey carried out by the state government.
According to the Karnataka government, the sero survey estimates that around 1.93 crore or 27.3% of the state’s population are either currently infected or already had the infection in the past, as of 16 September 2020.
The same survey has found that this number is around 30% in Bengaluru, one of the worst affected regions in the country.
“The whole idea of doing such a survey is to understand the prevalence of covid-19 in Karnataka," K.Sudhakar, Karnataka’s health minister said on Wednesday in Bengaluru.
The survey was carried out on 15,624 persons in 290 hospitals on persons above the age of 18 across all 30 districts of the state. However, experts point out that this could be an overestimation since the survey was carried out only in hospitals. The findings of the survey are also from September when the active case count was more than double of the over 40,000 mark.
The survey also found that 16.4% in the state who were already infected and 22% in Bengaluru had developed antibodies against the virus.
The survey provides an indication of the regions which have already witnessed a surge and those that are likely to see a rise in infections.
“Overall we feel that we are somewhere midway. Some districts are yet to see a surge," said Dr. Giridhar R Babu, one of the principal investigators of the survey and Professor and Head Lifecourse Epidemiology, Public Health Foundation of India.
