Coronavirus India | Mumbai home quarantine cases drop 28% as COVID-19 curve plateaus

BMC data has revealed that the number of COVID-19 patients under institutional quarantine has also gone down by 62 percent over the past month.

With Mumbai’s coronavirus curve gradually plateauing, the number of COVID-19 patients under home quarantine has declined 28 percent in the past month. At the same time, the number of COVID-19 patients under institutional quarantine has fallen by 62 percent.

As per data released by the Brihanmumbai Municipal Corporation (BMC) on July 4 – which is roughly a month ago – 2,46,870 people were under home quarantine. This figure decreased to 1,78,740 on August 4. The number of coronavirus patients quarantined at private institutions at that time was 12,374, which decreased drastically to 4,674, by August 4.

As most COVID-19 cases being reported at the moment are coming from residential buildings, BMC is stressing on home quarantine. Because of the decreasing number of COVID-19 patients being sent to institutional quarantine, more than 90 percent COVID Care Centres (CCC) are lying vacant. Hindustan Times reported that the Mumbai civic body has, in fact, instructed ward officers to shut down vacant CCCs.

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.

Commenting on this, Suresh Kakani, Additional Commissioner, BMC, said: “Earlier, we were getting infected cases from slums and had to isolate them at other places. We had rented out hundreds of vacant places to keep them under institutional quarantine. But now, with the recovery in slums, the load on CCCs has decreased.”

Mumbai saw nearly 60 percent of CCC-1 and CCC-2 beds occupied by asymptomatic and mildly symptomatic COVID-19 patients and high-risk contacts till June. At present, 92 percent of these beds are lying vacant. The same pattern has been noted in CCC facilities as well. Of the 72,656 beds in CCC facilities, only 6,065 beds are occupied at the moment.
