New COVID-19 strain: 6 UK returnees test positive for new coronavirus variant

Six persons who returned to India from the United Kingdom have tested positive for the new UK variant genome of SARS-CoV2.

India has reported six cases of the new coronavirus strain. As per a government statement, a total of 6 UK returnees have been found to be positive with the new UK variant genome. Three samples in NIMHANS of Bengaluru, 2 in CCMB, Hyderabad and 1 in NIV, Pune tested positive for the new variant of coronavirus.

"All these persons have been kept in single room isolation in designated Health Care facilities by respective state governments. Their close contacts have also been put under quarantine. Comprehensive contact tracing has been initiated for co-travellers, family contacts and others," the Ministry of Health and Family Welfare said, adding that genome sequencing on other specimens is going on.

The Ministry further said that the situation is "under careful watch and regular advice is being provided to the States for enhanced surveillance, containment, testing & dispatch of samples to INSACOG labs".

As per the statement, from November 25 to December 23, about 33,000 passengers arrived in India from the UK. Of these, 114 tested positive for COVID-19.

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.

"These positive samples have been sent to 10 INSACOG labs (NIBMG Kolkata, ILS Bhubaneswar, NIV Pune, CCS Pune, CCMB Hyderabad, CDFD Hyderabad, InSTEM Bengaluru, NIMHANS Bengaluru, IGIB Delhi, NCDC Delhi) for genome sequencing," Health Ministry added.

Explained: Are new coronavirus strains cause for concern?

The new UK Variant has already been reported by Denmark, Netherlands, Australia, Italy, Sweden, France, Spain, Switzerland, Germany, Canada, Japan, Lebanon and Singapore, so far.

Health experts in the UK and US have said that the UK strain seems to infect more easily than others, but there is no evidence yet it is more deadly. The strain is also concerning because it has so many mutations — nearly two dozen — and some are on the spiky protein that the virus uses to attach to and infect cells. That spike is what current vaccines target.
