State heterogeneity “indicates the possibility of future waves of infection,” the federal government warned, including that individuals ought to journey provided that absolutely vaccinated. 

The general seroprevalence was 67.6 per cent within the ICMR’s 4th nationwide COVID sero survey, held in June and July, that concerned over 28,975 people (adults and kids), other than 7,252 healthcare staff, in 70 districts throughout 21 states the place earlier three rounds have been additionally performed.

The federal government stated the findings present there’s a ray of hope, however “there is no room for complacency” and COVID-appropriate behaviour and group engagement should be maintained.

Addressing a press convention, ICMR Director Common Balram Bhargava stated, “Two-thirds of the general population above the age of six, or 67.6 per cent were found to have SARS-CoV-2 antibodies in the latest national sero survey.”

“A third of the population did not have SARS-CoV-2 antibodies, which means approximately 40 crore people are still vulnerable to COVID-19 infection,”

These with out antibodies run the chance of an infection waves, Dr Bhargava stated.

Greater than half of the kids (6-17 years) have been sero-positive and sero-prevalence was comparable in rural and concrete areas, he knowledgeable. In addition to, 85 per cent of the surveyed healthcare staff had antibodies in opposition to SARS-CoV-2 and one-tenth have been nonetheless unvaccinated.

The sero survey was performed over 28,975 people (adults and kids), other than 7,252 healthcare staff in 70 districts throughout 21 the place earlier three rounds have been additionally performed.

Dr Bhargava stated that when India begins reopening faculties, it is going to be clever to start with the first part as youngsters have a decrease variety of ace receptors to which virus attaches, making them significantly better at dealing with viral infections than adults.


The federal government goals to vaccinate over 108 crore individuals by the top of this yr. 

The seroprevalence in rural areas was discovered to be 66.7 per cent and barely greater in city at 69.6 per cent.As per vaccination standing, it was seen in 62.3 per cent amongst unvaccinated individuals, 81 per cent amongst those that took single dose of vaccine whereas it was 89.8 per cent in absolutely vaccinated individuals.

Within the first sero survey performed in Could-June 2020, the seroprevalence was 0.7 per cent; within the second survey in August-September 2020, it was 7.1 per cent; within the third sero survey performed in December-January, 2021 it was 24.1 per cent.

“Overall seroprevalence in healthcare workers was 85.2 per cent. We studied 7,252 healthcare workers and 10 per cent had not taken the vaccine while 13.4 per cent had taken one dose and 76.1 per cent had taken both doses of vaccine,” he stated.

An vital level to recollect right here is that the nationwide sero survey is just not an alternative choice to native (state or district) stage survey, Dr Bhargava stated, including it’s simply giving a chicken’s eye view or a panoramic image of what’s occurring within the nation.

However there’s heterogeneity which is going on from state to state, district to district and we ought to be cognisant of that, he stated and knowledgeable that stat- led sentinel sero-surveillance will inform additional state-level motion. “State heterogeneity indicates the possibility of future waves of infection. There might be some states where the population which is vulnerable is much higher there and so chances of future waves are higher in those states.”

“Societal, public, religious and political congregations should be avoided. Non-essential travels should be discouraged and travel only if fully vaccinated,” he stated.

NITI Aayog Member (Well being ) Dr V Okay Paul stated 40 crore individuals don’t have any antibodies and the pandemic is on no account over. The second wave remains to be persisting and the hazard of recent outbreaks remains to be very a lot there, he stated.

“…that 40 crore people have no antibodies, we would like them to gain protection through vaccination and not the infection and that is the endeavour that this nation is mounting,” he stated.

As a result of such a big pool of susceptible inhabitants remains to be amongst us – one out of three – subsequently the pandemic is on no account over,.. . the general vulnerability for the nation nonetheless stays and that’s very evident,” he said.

On the way forward, Dr Bhargava highlighted the need to ensure full vaccination of all healthcare workers as soon as possible, accelerating vaccination coverage in vulnerable population groups and ensuring adherence to non-pharmaceutical interventions.

He also stressed on continued tracking of Covid-infection in SARI cases in district hospitals.

“That’s one other crucial instrument that we use the SARI (Extreme acute respiratory an infection sufferers) and take a look at them for COVID and rule out if there’s any sudden spike of COVID-19 in SARI sufferers. We have to determine clusters and scientific severity and INSACOG is monitoring variants of concern,” he said.

Many states have done their own sero surveys and that will be very helpful in guiding the response to the pandemic.

Dr Paul said the third sero survey was in December-January, which may be taken as the seroprevalence post the end of the first wave and the rise in sero-positivity that can be seen has two factors to it.

“One is the second wave that’s the struggling that the Delta variant inflicted on us but in addition a part of sero-positivity is coming from vaccination protection and the gradient between vaccinated and unvaccinated will be seen,” he said.

On the situation in the country, Dr Paul said Kerala is still “static to slight rise” and Maharashtra is seeing some decline. Andhra Pradesh is still a cause of concern and 46 districts have more than 10 per cent positivity, he said.

He said some states have more than 10 per cent positivity. “It testifies to the truth that this stage of seropositivity doesn’t be certain that the pandemic is over and it’s on the market,” he warned.

On the vaccine scarcity in some states, Dr Paul stated the states and UTS are knowledgeable two weeks upfront in regards to the availability of the vaccines, in order that they will plan accordingly.
