Coronavirus India update: With decrease of over 10%, decline of active Covid-19 cases continues

The declining trend of Covid-19 cases in India continued with 2,09,918 new cases recorded in the last 24 hours — marking a reduction of over 10 percent in the daily cases in comparison to the day before.

This confirms the understanding that the third wave of the pandemic in India, largely triggered by the highly contagious Omicron variant, may be ebbing.

The active caseload in the country which was 18,84,937 on January 30 also came down by 53, 669, or nearly 3 percent, and stood at 18,31,268 on January 31.

Moreover, the rolling average of weekly Covid-19 test positivity rate in India is now under 16%, as per the statistics shared by the Union health ministry which also showed that the daily test positivity rate has come down to 15.77 percent.

A total of 959 deaths, however, were recorded in the last 24 hours, 374 of which were added as part of data reconciliation exercise in Kerala. Registering 101 fresh deaths during the 24-hour period, the southern state also recorded the highest number of deaths due to the infectious disease in India on January 31.

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.

With this, the number of fatalities confirmed due to the infectious disease in India has reached to 4,950,50.

On a positive note, there are now only 4 states and Union Territories that include Andhra Pradesh, Chhattisgarh, Kerala and Manipur that noted a rise in active cases, while the rest of states registered a significant decline in cases.

Maharashtra, which has been seeing the worst of the pandemic, almost since its beginning in 2020, recorded the sharpest drop of 16,621 cases in the total active cases in a day.
