Close to 80 percent patients may come down with a light cold and fever and recover on their own without getting to know that they were infected by the novel coronavirus, or COVID-19, Indian Council of Medical Research (ICMR) Director Balram Bhargava said.

Elaborating on the nature of COVID-19, Bhargava said 20 percent of those infected may show symptoms like cough, cold and fever. Of this, only 5 percent require hospitalisation, he added.

India has 390 reported cases of coronavirus infection including foreign nationals. As many as 24 people have recovered, while seven have died.

ICMR is conducting an evaluation on the basis of COVID-19 cases and deaths reported so far in the country, Bhargava explained, adding that such an evaluation can help gauge how many more such cases and deaths can increase by March 24.

COVID-19 Vaccine

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.

On the approval given to private labs to conduct coronavirus tests, Bhargava said there have been 60 registrations so far and more applications are under consideration.

Four private labs in Maharashtra and one each in Gujarat and Karnataka have so far been approved to conduct COVID-19 tests, the ICMR website stated.

Besides 111 government labs are already functional in this regard, he said, adding that the most important thing to remember is that indiscriminate testing is not to be done and the thrust should be on isolation".

The ICMR director asserted that a lockdown is the most essential thing for breaking the chain of transmission.
