'Yellow alert' to continue in Delhi for now, authorities in wait-and-watch mode

The ‘yellow alert’ entails restrictions like night curfew, closure of schools and colleges, opening of shops selling non-essential items on an odd-even basis, halved seating capacity in Metro trains and buses, among other things.

The DDMA on Wednesday decided that Covid-related restrictions imposed in Delhi under the ‘yellow alert’ will continue for the time being and authorities will monitor the situation for a while before deciding on fresh curbs, official sources said.

The decision was taken at a meeting chaired by Lt Governor Anil Baijal, who is also the chairperson of the Delhi Disaster Management Authority. It was attended by Chief Minister Arvind Kejriwal and experts.

The DDMA on Tuesday declared a ‘yellow alert’ under the Graded Response Action Plan (GRAP) in the city amid a spike in coronavirus cases following the emergence of the virus’ Omicron variant.

The ‘yellow alert’ entails restrictions like night curfew, closure of schools and colleges, opening of shops selling non-essential items on an odd-even basis, halved seating capacity in Metro trains and buses, among other things.

The DDMA has decided that curbs imposed under the ‘yellow alert’ will continue in the national capital for now, the sources said.

The authorities are in favour of monitoring the situation for some more time and to avoid imposing further restrictions under ‘amber alert’, they said.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

An ‘amber alert’ is declared when the positivity rate is recorded at one per cent or above for two consecutive days.

“It was discussed that most Covid cases are asymptomatic and mild and there are fewer hospitalisations, which indicates that the situation is not that bad,” a source said.

During the meeting, it was also decided to ensure strict implementation of restrictions imposed under the ‘yellow alert’. In case the situation worsens, emergency measures may be imposed, the sources said.

On Tuesday, Delhi recorded 496 fresh COVID-19 cases, the highest since June 4, while the positivity rate stood at 0.89 per cent, according to health department data.

The total number of Omicron cases in the city stood at 165, the data stated.
