Community transmission of COVID-19 on in many parts of India: Experts

New Delhi: Amid a massive spurt in coronavirus cases in India, experts on Saturday came down hard on the ICMR for its serosurvey findings to assert that there was no community transmission of COVID-19, saying it was not reflective of the current situation and the government was showing “obstinacy” in accepting the truth.

Emphasising that community transmission was on in many parts of the country, the experts asked the government to admit it so that people don’t get complacent.

The assertion by experts from the field of virology, public health and medicine came after Indian Council of Medical Research (ICMR) Director-General Balram Bhargava at a media briefing on Thursday said that India is definitely not in the community transmission stage of COVID-19 spread while releasing the findings of the survey.

India’s first serosurvey to monitor the trend of coronavirus infection transmission found that 0.73 per cent of the 26,400 people surveyed from about 65 districts were exposed to coronavirus.

AIIMS former director Dr M C Mishra said there is no doubt that there has been community transmission in several parts of the country.

“With the mass exodus and the country unlocking, it has become more rapid and the disease has reached areas where there were no cases. It is high time the government comes to fore and acknowledges it so that people become more alert and do not become complacent,” Mishra told PTI.

Talking about the ICMR sero-survey, he said the sample size of around 26,400 people is quite inadequate to capture the scale of the spread of the infection, especially keeping in mind the large population and the diversity of the country.

Leading virologist Shahid Jameel said India reached the community transmission stage a long time ago. “It’s just that the health authorities are not admitting it. Even ICMR’s own study of SARI (severe acute respiratory illness) showed that about 40 per cent of those who tested positive for SARS-CoV-2 did not have any history of overseas travel or contact to a known case. If this is not community transmission, what is,” said Jameel.

Chairman of one of the empowered groups set up to deal with the pandemic and NITI Aayog member Dr V K Paul had said the results of the survey indicate the situation of the country around April 30 as the study was conducted mostly around third week of May and antibodies against an infection take around 15 days to develop.

While the sero-survey to estimate the fraction of population infected with SARS-CoV-2 in the general population has been completed, the survey in containment zones of hotspot cities is ongoing.

COVID-19 tally breached the three-lakh mark on Saturday with a record single-day spike of 11,458 infections, while the death toll rose to 8,884 with 386 new fatalities, the Union Health Ministry said. With a COVID-19 caseload of 3,08,993, India is now the fourth worst-hit nation by the pandemic.

The ICMR sero-survey found that lockdown and containment measures were successful in preventing rapid spread of the disease, but a large proportion of the population still remains susceptible.

Bhargava had said the study surveyed a total of 83 districts with 26,400 people enrolling for it and 28,595 households were visited. The surveyed districts were categorised into – zero cases, low incidence, medium incidence and high incidence and were selected based on the incidence of reported COVID-19 cases as on April 25.

The findings shared with the media stated that data from 65 districts has been compiled till now
