The first comorbidity survey among Calcuttans came to an end on Wednesday with over 7.69 lakh households out of the targeted 10 lakh covered.

Firhad Hakim, the chairperson of the Calcutta Municipal Corporation’s board of administrators, said such surveys would be conducted in regular intervals to keep the data updated.

The data from the first survey, which was launched to further fine-tune the state government’s Covid response, is likely to be digitised before Durga Puja.

“We have ended the survey for now. The work to digitise the data is underway and we are targeting to complete the digitisation before Puja,” Hakim told Metro. “We will keep updating the data with repeat surveys in regular intervals.”

About 98,000 household data have already been uploaded, said a CMC official.

This is the first time data on Calcuttans with comorbidities — medical conditions such as hypertension, diabetes, cancer and COPD — will be available with the CMC and the state health department. “The finding will serve as a critical input in the framing of health policies,” a doctor said. “The survey will also help the authorities tailor individual responses…. Covid patients with comorbidities have a higher chance of turning critical compared with those who do not have any comorbidity.”
