Covid cases rising in Delhi but people not developing severe disease: Satyendar Jain

"Though Covid cases have increased in Delhi, people are not developing severe disease and the hospitalisation rate is low. This is because our population is fully vaccinated and a large number of people have had the disease in the past," Jain told reporters here.

Delhi Health Minister Satyendar Jain on Thursday said that though COVID-19 cases have increased in the capital, people are not developing severe disease and the hospitalisation rate is low. He attributed the low hospitalisation rate to vaccination and naturally acquired immunity.

"Though Covid cases have increased in Delhi, people are not developing severe disease and the hospitalisation rate is low. This is because our population is fully vaccinated and a large number of people have had the disease in the past," Jain told reporters here. He also said there is no need to panic about Covid cases among children. Several serosurveys have shown that though the infection rate among children and adults is almost the same, the severity of disease is "very low" in children.

With the national capital witnessing an uptick in coronavirus infections over the past few days, the number of active cases on Wednesday stood at 4,832, up from 601 on April 11, according to health department data. However, the hospitalisation rate so far has been low, accounting for less than three per cent of the total active cases, the health department's bulletin said on Wednesday.

As many as 129 COVID-19 patients are admitted to Delhi hospitals, while 3,336 are recuperating in home isolation, it said. Earlier, when Delhi would have 5,000 active cases, Jain said, 1,000 people would require hospitalisation. Of the 9,390 beds available for COVID-19 patients in various hospitals, only 148 (1.58 percent) are occupied.

"We have around 1,000 beds at present. We ramp up their number if needed," he said.

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.
