Passengers arriving from the United Kingdom will not be sent to mandatory institutional quarantine if they test negative for COVID-19, the Delhi government has said on January 30.
The passengers who test negative in the RT-PCR test will now have to be quarantined at home for all 14 days.
Earlier, it was mandatory for passengers coming from the UK to go through a seven-day mandatory institutional quarantine followed by a seven-day home quarantine. This protocol was put in place amid concerns that the new coronavirus strain found in the UK is more infectious.
All such passengers must carry a COVID-19 negative certificate from a test conducted within 72 hours of their journey. Passengers will still have to quarantine for 14 days even if they have tested negative.
Frequently Asked Questions
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.
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.
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.
As of January 29, the total number of people in India infected by the UK strain stood at 166.Click here for Moneycontrol’s full coverage of the coronavirus pandemic
