Dr Diptendra Sarkar of the state-run SSKM Hospital said that with the countrywide lockdown having been in force for nearly 70 days and the government, both at the Centre and the state, having shored up resources during the period to deal with the disease, it was time for a gradual easing of restrictions.
With West Bengal Chief Minister Mamata Banerjee announcing the easing of lockdown restrictions in the state, a renowned doctor said that following ramping up of COVID-19 tests, the government seems to be gradually shifting towards the Sweden or Taiwan model to contain the pandemic. Dr Diptendra Sarkar of the state-run SSKM Hospital said that with the countrywide lockdown having been in force for nearly 70 days and the government, both at the Centre and the state, having shored up resources during the period to deal with the disease, it was time for a gradual easing of restrictions.
"I feel that they are shifting the model, they were till now going by the hammer and the tongs model which is a lockdown," he said.
Referring to the 72-day lockdown in Wuhan, he said that a lockdown of 60 to 70 days brings down the number of cases of infection.
"The Sweden model or that in Taiwan or South Korea, where instead of lockdown they stressed on testing and segregating high-risk population, they have got equal success," Sarkar said.
Frequently Asked Questions
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.
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.
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.
He opined that the government had enforced a strict lockdown in the beginning owing to lack of testing facilities, but now with a countrywide testing capacity of around one lakh per day, the government is shifting towards the Sweden or South Korea or Taiwan model from the lockdown model.
He said that according to a study by the Imperial College of London, if 60 per cent of the population wear ordinary masks, then it can prevent 90 per cent spread of infections.
"As an epidemic progresses, a virus in order to survive reduces fatality among its host and gradually loses its vigour," Sarkar said.
While agreeing that the lockdown has to be lifted at some point of time, the Association of Health Service Doctors secretary Dr Manas Gumta expressed his reservations on the manner in which it was being eased in the state.
He said that it is not about one-upmanship with the central government over bringing of thousands of people by trains from other states, including the most affected Maharashtra and Gujarat, but there has to be a scientific basis on the way the lockdown is lifted.
"Lockdown is simply for buying time by which the health infrastructure can be readied to deal with the pandemic effectively as also for non-COVID patients," he said, adding that it has to be lifted but in a phased manner.
"The way the lockdown is being practically lifted without any preparation, it may lead to a catastrophe," he said.
Gumta said the government needs revenue and people also require livelihood and as such lockdown has to be lifted gradually.
"But what is the purpose of opening up religious places, at this juncture, where people may congregate in large numbers," he questioned. He said that with work from home becoming common in various sectors, there was no need to open up all sectors with full workforce.Gumta also opined that the government should introduce shift systems in offices so as to ease the crowding of many people at a time, in workplaces as well as in public transport.
