Health | Coronavirus exposes India’s weak healthcare foundation

While the current situation of COVID-19 in India is not a cause for alarm, this is another reminder that our public health system needs to be strengthened to face such situations.

On January 30, the second meeting of the emergency committee convened by the WHO Director General under the International Health Regulations (IHR) (2005) declared the outbreak of the novel coronavirus (2019-nCov) as meeting the criteria for a Public Health Emergency of International Concern (PHEIC). It recommended that all countries “be prepared for containment, including active surveillance, early detection, isolation and case management, contact tracing and prevention of onward spread of 2019-nCoV infection, and to share full data with WHO”.

According to the latest data from the WHO, as of 17 February, there were 71,429 confirmed cases of COVID-19 globally, and 1,775 deaths. While most of this is reported from China, there have been 794 confirmed cases from other countries, including three deaths. In India so far there have been three positive cases, all in Kerala, while a large number of people have been kept under community and hospital surveillance across the states. Kerala is releasing regular updates about quarantines, tests and hospitalisations and the Ministry of Health and Family Welfare (MoHFW) of the Government of India has stated that the “situation is under control in India”.

The response of the health system and the government in Kerala has been appreciated for its role in ensuring there is no panic and for its effective surveillance. The MoHFW is also regularly monitoring the situation across India and has advised states to strengthen disease surveillance and enhance awareness on personal hygiene and disease prevention.

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.
