Coronavirus: Weekly case positivity in 300 districts over 5%; don't treat Omicron as common cold, says Centre

As many as 300 districts in India are reporting weekly Covid case positivity of more than 5 percent, the Union government said on Wednesday as it urged people not to treat infection due to Omicron variant as common cold and get vaccinated.

It said Maharashtra, West Bengal, Delhi, Tamil Nadu, Karnataka, Uttar Pradesh, Kerala and Gujarat are emerging as states of concern due to the rise in Covid cases there.

Addressing a press conference, Joint Secretary in Health Ministry Lav Agarwal said a sharp rise in COVID-19 infections has been noted in India with the case positivity climbing to 11.05 per cent on Wednesday from 1.1 per cent on 30 December.

Concurrently, Covid cases have been rising globally with 10 January recording the highest ever single-day rise of 31.59 lakh cases worldwide, he said.

The official said that currently, 300 districts in India are reporting weekly case positivity of more than 5 percent.

Informing the press conference that 19 states have over 10,000 active Covid cases, Agarwal said Maharashtra, West Bengal, Delhi, Tamil Nadu, Karnataka, Uttar Pradesh, Kerala and Gujarat are emerging as states of concern due to the rise in Covid cases there.

Stressing on the importance of getting inoculated, he quoted the World Health Organisation to say that vaccine effectiveness against hospitalization appears to be substantially higher than against symptomatic COVID-19 disease.
NITI Aayog Member (Health) V K Paul said, “Omicron is not the common cold, cannot take it lightly. We need to be vigilant, get vaccinated and follow Covid-appropriate behaviour.”

“Vaccination is an important pillar in our Covid response programme,” he added.

India added 1,94,720 new infections to its tally of COVID-19 cases pushing it to 3,60,70,510, according to the Union Health Ministry data on Wednesday.

Active cases have increased to 9,55,319, the highest in 211 days, while the death toll has climbed to 4,84,655 with 442 fresh fatalities. Of the total 4,868 cases of the Omicron variant, 1,805 people have recovered or migrated so far.

The Centre on Wednesday said lateral flow tests, which includes rapid-antigen and home-antigen tests, can detect Covid from the third day after exposure to the virus to day eight while the RT-PCR test can diagnose the infection for up to 20 days.

At a press conference, Indian Council of Medical Research (ICMR) Director-General Dr Balram Bhargava said on the first day one will test negative whatever tests they undertake.

“It takes time for the virus to grow in your system and that is known as the latent period. From day three it will be detectable in the Lateral Flow Tests and up to day eight which is the infectious period.

“That is why, the discharge policy and home isolation policy are focusing on the seven-day period,” Bhargava explained.

He said that RT-PCR test results will continue to be positive even after day eight because certain RNA particles which are non-infective will continue to be shed and will continue to cause test results to be positive.”

The ICMR director-general said that for Omicron, lateral flow tests have become the backbone.

Bhargava said that according to government advisory, high-risk contacts of confirmed Covid cases, identified based on age or comorbidities, those undertaking inter-state travel do not need to get tested.

Also, asymptomatic individuals in community settings, patients who stand discharged according to home-isolation guidelines and those being discharged from a COVID-19 facility under the revised discharge policy do not need to get tested, he said.

However, Bhargava stressed on seven-day home quarantine for all contacts of any positive case according to the guidelines and added that they should continue to wear a mask.

Referring to the Advisory on Purposive Testing Strategy for COVID-19 in India issued by ICMR recently, he said symptomatic individuals, even if they test negative on a home test or rapid-antigen test should go for RT-PCR test.
According to the advisory, testing can be undertaken either through RT-PCR, TrueNat, CBNAAT, CRISPR, RT-LAMP, Rapid Molecular Testing Systems or through the rapid-antigen test.

A positive point-of-care test and molecular test is to be considered confirmatory, without any repeat testing. Symptomatic individuals, testing negative on home/self-test or rapid-antigen test should undertake RT-PCR test, the advisory stated.

In community settings, symptomatic individuals, at-risk contacts (elderly and individuals with comorbidity) of laboratory-confirmed cases may be tested.

Also, individuals undertaking international travel may be tested.

In hospital settings, testing may be undertaken as per the discretion of the doctor with considerations such as no emergency procedure should be delayed for lack of a test and patients should not be referred to other facilities for lack of a testing facility, the advisory stated.

All arrangements should be made to collect and transfer samples to testing facilities, mapped to the health facility.
There are 3,128 testing laboratories and India’s daily RT-PCR testing capacity is over 20 lakh, Bhargava said.
