21 cases of COVID-19 'Delta plus' variant found in Maharashtra: Minister

The highest nine cases were reported in Ratnagiri, followed by seven in Jalgaon, two in Mumbai, and one case each in Palghar, Thane and Sindhudurg districts, Tope told reporters.

Twenty one cases of the ''Delta plus'' variant of COVID-19, considered highly infectious, have been found in Maharashtra so far, state Health Minister Rajesh Tope has said.

The highest nine cases were reported in Ratnagiri, followed by seven in Jalgaon, two in Mumbai, and one case each in Palghar, Thane and Sindhudurg districts, Tope told reporters.

He said 7,500 samples from different parts of the state were collected and sent for laboratory testing. These samples were collected since May 15 and their genome sequencing was done, the minister said.

Genome sequencing allows the tracking of small mutations in SARS-CoV2, the virus that causes COVID-19, meaning chains of transmission can be identified.

The scientific process also assists in identifying missing links in the chain of transmission. Tope said complete information about the people detected with the ''Delta plus'' variant is being sought, including their travel history, whether they were vaccinated or not, and if they were reinfected.

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.

Their contacts are being traced and tested, the minister said, adding that information on the mutation of Delta and Delta plus variants is also being scrutinised.

Last week, the Maharashtra health department made a presentation where it said the newly identified ‘Delta plus’ variant may trigger a third wave of the pandemic in the state. Chief Minister Uddhav Thackeray, state COVID-19 task force members and health department officials had attended the presentation.

The new Delta plus variant has been formed due to a mutation in the Delta or B.1.617.2 variant, first identified in India and one of the drivers of the deadly second wave.

Though there is no indication yet of the severity of the disease due to the new variant, Delta plus is resistant to the monoclonal antibody cocktail treatment for COVID-19 recently authorised in India.

On Monday, Maharashtra reported 6,270 new coronavirus cases, a four-month low daily count, taking its COVID-19 tally to 59,79,051, while 94 deaths pushed the toll to 1,18,313, as per the state health department.
