India coronavirus: Why is India reopening amid a spike in cases?

India is roaring – rather than inching – back to life amid a record spike in Covid-19 infections. The BBC’s Aparna Alluri finds out why.

On Saturday, India’s government announced plans to end a national lockdown that began on 25 March.

This was expected – the roads, and even the skies, have been busy for the last 10 days since restrictions started to ease for the first time in two months. Many businesses and workplaces are already open, construction has re-started, markets are crowded and parks are filling up. Soon, hotels, restaurants, malls, places of worship, schools and colleges will also reopen.

But the pandemic continues to rage. When India went into lockdown, it had reported 519 confirmed cases and 10 deaths. Now, its case tally has crossed 173,000, with 4,971 deaths. It added nearly 8,000 new cases on Saturday alone – the latest in a slew of record single-day spikes.

So, why the rush to reopen?

The lockdown is simply unaffordable

“It’s certainly time to lift the lockdown,” says Gautam Menon, a professor and researcher on models of infectious diseases.

“Beyond a point, it’s hard to sustain a lockdown that has gone on for so long – economically, socially and psychologically.”

From day one, India’s lockdown came at a huge cost, especially since so many of its people live on a daily wage or close to it. It put food supply chains at risk, cost millions their livelihood, and throttled every kind of business – from car manufacturers to high-end fashion to the corner shop selling tobacco. As the economy sputtered and unemployment rose, India’s growth forecast tumbled to a 30-year-low.

Raghuram Rajan, an economist and former central bank governor, said at the end of April that the country needed to open up quickly, and any further lockdowns would be “devastating”.

The opinion is shared by global consultant Mckinsey, whose report from earlier this month said India’s economy must be “managed alongside persistent infection risks”.

“The original purpose of the lockdowns was to delay the spike so we can put health services and systems in place, so we are able handle the spike [when it comes],” says Dr N Devadasan, a public health expert. “That objective, to a large extent, has been met.”

In the last two months, India has turned stadia, schools and even train coaches into quarantine centres, added and expanded Covid-19 wards in hospitals, and ramped up testing as well as production of protective gear. While grave challenges remain and shortages persist, the consensus seems to be that the government has bought as much time as possible.

“We have used the lockdown period to prepare ourselves… Now is the time to revive the economy,” Delhi Chief Minister Arvind Kejriwal said last week.

The silver lining

For weeks, India’s relatively low Covid-19 numbers baffled experts everywhere. Despite the dense population, disease burden and underfunded public hospitals, there was no deluge of infections or fatalities. Low testing rates explain the former, but not the latter.

In fact, India made global headlines not for its caseload but for its botched handling of the lockdown – millions of informal workers, largely migrants, were left jobless overnight. Scared and unsure, many tried to return home, often desperate enough to walk, cycle or hitchhike across hundreds of kilometres.

Perhaps the choice – between a virus that didn’t appear to be wreaking havoc yet, and a lockdown that certainly was – seemed obvious to the government.

But that is changing quickly as cases shoot up. “I suspect we will keep finding more and more cases, but they will mostly be asymptomatic or will have mild symptoms,” Dr Devadasan says.

The hope – which is also encouraging the government to reopen – is that most of India’s undetected infections are not severe enough to require hospitalisation. And so far, except in Mumbai city, there has been no dearth of hospital beds.

India’s Covid-19 data is spotty and sparse, but what it does have suggests that it hasn’t been as badly hit by the virus as some other countries.

The government, for instance, has been touting India’s mortality rate as a silver lining – at nearly 3%, it’s among the lowest in the world.

But some are unconvinced by that. Dr Jacob John, a prominent virologist, says India has never had, and still doesn’t have, a robust system for recording deaths – in his view, the government is certainly missing Covid-19 deaths because they have no way of knowing of every fatality.

Image caption Indians are venturing out again but it’s unclear how many of them are asymptomatic.

And, he says, “what we must aim for is flattening the mortality curve, not necessarily the epidemic curve”.

Dr John, like several other experts, also predicts a peak in July or August, and believes the country is reopening so quickly because the “government realised the futility of such leaky lockdowns”.

A shift in strategy

So is the government gearing up for another lockdown when the peak comes?

While Dr Menon believes the lockdown was well-timed, he says it was too focused on cases coming from abroad.

“There was a hope that by controlling that, we could prevent epidemic spread, but how effective was our screening [at airports]?”

Now, he adds, is the time for “localised lockdowns”.

The federal government has left it to states to decide where, how and to what extent to lift the lockdown as the virus’ progression varies wildly across India.

Maharashtra alone accounts for more than a third of India’s active cases. Add Tamil Nadu, Gujarat and Delhi, and that makes up 67% of the national total.

But other states – such as Bihar – are already seeing a sharp uptick as migrant workers return home.

“Initially, most of your cases were in the cities,” Dr Devadasan says. “But we kept the migrant workers in cities and didn’t allow them to go home. Now, we are sending them back. We have facilitated transporting the virus from urban areas to rural areas.”

While the government has said how many infections have been avoided – up to 300,000 – and lives saved – up to 71,000 – by the lockdown, there is no indication of what lies ahead.

There is only advice: The day the government began to ease restrictions, Mr Kejriwal tweeted, urging people to “follow discipline and control the coronavirus disease” as it was their “responsibility”.

Because the alternative – of curfews and constant policing – is unsustainable.

“My worry is more the circumstances of people – it’s not as though they have an option to practise social distancing,” Dr Menon says.

And they don’t – not in joint family homes or one-room hovels packed together in slums, not in crowded markets or busy streets where jostling is second nature, or in temples, mosques, weddings or religious processions where more is always merrier.

The overwhelming message is that the virus is here to stay, and we have to learn to live with it – and the only way to do that, it appears, is to let people live with it.

India coronavirus: Can the Covid-19 lockdown spark a clean air movement?

When India shut down last month and suspended all transport to contain the spread of coronavirus, the skies over its polluted cities quickly turned an azure blue, and the air, unusually fresh.

As air pollution plummeted to levels unseen in living memory, people shared pictures of spotless skies and even Himalayan peaks from cities where the view had been obscured by fog for decades.

On one social messaging group, a resident of the capital, Delhi, which regularly records some of the foulest air in the world, celebrated the city’s “alpine weather“. Politician and author Shashi Tharoor wrote that the “blissful sight of blue skies and the joy of breathing clean air provides just the contrast to illustrate what we are doing to ourselves the rest of the time”.

Less than six months ago, Delhi was gasping for breath. Authorities said air quality had reached “unbearable levels”. Schools were shut, flights were diverted, and people were asked to wear masks, avoid polluted areas and keep doors and windows closed.

Delhi and 13 other Indian cities feature on a list of the world’s 20 most polluted. It is estimated that more than a million Indians die every year because of air pollution-related diseases. Industrial smoke, vehicular emissions, burning of trash and crop residue, and construction and road dust are the major contributors.

As urban Indians gazed at the skies and breathed clean air inside their homes, researchers hunkered down to track data on how the grinding lockdown – now extended to 3 May – was impacting air pollution across the country.

“This was an unprecedented opportunity for us to take a close look at how air pollution levels have responded to an extraordinary development,” Sarath Guttikunda, who heads Urban Emissions, an independent research group that provides air quality forecasts, told me.

Federal pollution control authorities quickly reported a marked improvement in air quality levels in 85 cities.

Dr Guttikunda and his team of researchers looked at the data spewed out by the 100-odd air quality monitoring stations all over India. They decided to concentrate on the capital Delhi and its suburbs – a massive sprawl called the National Capital region, where more than 20 million people live. Last winter, air pollution here had reached more than 20 times the World Health Organization’s safe limit.

The deadliest particle in Delhi’s foul air is the tiny but deadly PM 2.5, which increases the likelihood of respiratory and cardiovascular diseases. They primarily come from combustion – fires, automobiles and power plants.

Urban Emissions found the levels of PM 2.5 in Delhi during the lockdown plummeted to 20 micrograms per cubic metre with a 20-day average of 35.

To put this into context, between 2017 and 2019, the monthly average of PM 2.5 in the capital was up to four times higher. (The national standard is set at 40, and the WHO has an annual average guideline of just 10 micrograms per cubic metre.)

“If 35 is the average lowest available PM2.5 with limited local emissions, it means that at least 70% of the pollution is locally generated,” Mr Guttikunda told me.

His study also found a marked dip in PM 10, caused mainly by road and construction dust, and nitrogen dioxide, which comes mainly from vehicular emissions, and nearly 90% of vehicles are off the road.

“The current crisis has shown us that clear skies and breathable air can be achieved very fast if concrete action is taken to reduce burning of fossil fuels,” says Sunil Dahiya, of the Centre for Research on Energy and Clean Air, which has also been tracking air pollution levels during the lockdown.

But will this prompt change? After all, urban Indians’ and the media’s panic and outrage during the deadly winter pollution every year soon gets lost in the fog of summer heat and concerns over monsoon rains and droughts.

“We don’t yet have a democratic demand for clean air,” Arunabha Ghosh, Chief Executive Officer of the Council on Energy, Environment and Water, a leading climate think tank, told me. Orders to clean up the air have almost always come from the courts, responding to pleas by NGOs.

However, Dr Ghosh still hopes that “the experience of blue skies and fresh air could be a trigger to create a democratic demand for clean air in India”.

Crises often trigger life changing reforms. A fatal four-day “pea-souper” that engulfed London in 1952 and killed thousands provoked the passing of the Clean Air Act to reduce the use of smoky fuels.

China tried to clean up its air several times before hosting marquee international events – like the Beijing Olympics in 2008, the World Expo in Shanghai and the Guangzhou Asian Games in 2010 – before sliding back to grey, smoky skies.

But many believe the 2014 Apec meeting in Beijing, when China hosted 21 heads of Asia-Pacific economies, was a turning point. The rare blue skies over Beijing spawned the phrase ‘Apec blue‘. In a rush to clean its air, China introduced a set of far-reaching measures. Over the next four years, this resulted in a 32% drop in average pollution across major Chinese cities.

So could a lockdown to prevent the spread of a pandemic, which has imperilled the health and livelihoods of millions, trigger similar policy changes to clean up India’s air?

Could it move to a shift in reducing traffic on the road by asking people to work from home in shifts now that millions have experienced clean air for the first time in years? (Facing energy shortages after the loss of the Fukushima nuclear power plant, Japan unleashed a Cool Biz campaign to cut down air conditioning in workplaces and reduce carbon emissions by asking office workers to shed their suits.)

Or can India use some of the money from an inevitable stimulus to help kick-start the economy go towards helping green industries? Renewables, experts say, creates more jobs than coal: India has already created nearly 100,000 jobs in solar and wind energy firms.

Can the country use the windfall revenues accruing from the steep decline in oil prices – most of India’s oil is imported – to provide rebates to polluting factories to set up much-needed emission control equipment?

“We have to learn lessons to deploy the economic recovery from the pandemic. We need growth, jobs and sustainable development,” says Dr Ghosh. Cleaning up the air could be the key. For too long, India – and Indians – have ignored their right to breathe easy.

What’s more, if China can reduce air pollution by 32% in four-and-a-half years, why can’t India pledge to reduce pollution by 80% in 80 cities by 2027, which is our 80th anniversary of Independence? asks Dr Ghosh.

It’s a good question.

Chinese fighter jets seen in skies over Beijing as preparations for National Day parade step up

  • October 1 event is intended to be a showcase for military’s progress under Xi Jinping, with J-20 stealth fighters set to take pride of place
  • Domestically developed weapons are main focus of event despite long-standing problems in building  aircraft engines

China has stepped up intensive rehearsals for the upcoming National Day parade, which military insiders say is designed to showcase the achievements of Chinese President Xi Jinping’s modernisation drive.

The parade on October 1 will mark the 70th anniversary of the founding of the People’s Republic and will focus on weapons developed since Xi came to power in late 2012, despite long-standing problems in aircraft engine development.

Video clips circulating on mainland social media in recent days have shown at least seven types of aircraft – including the KJ-2000 airborne early warning and control aircraft and J-10 and J-11B fighter jets – taking part in rehearsals over the countryside  around Beijing.

A military insider said the country’s first stealth fighter jet, the J-20, had been rehearsing over the western suburbs of the capital since April.

“There will be up to seven J-20 displayed in the military parade, which is the largest formation since its formal deployment to the Chinese air force in 2017,” the military insider said.

“The J-20 has entered mass production. So far at least 70 J-20s have been made, even though all of them are still equipped with Russian AL-31 engines.”

Earlier this month, the People’s Liberation Army Air Force released a video of a flight of seven J-20s, the largest formation seen so far, suggesting that the fifth-generation warplane has gone into mass production as an arms race with the United States mounts in the region.

The second-largest J-20 formation was shown in an air force video for PLA Day on August 1, when five of the jets were shown.

China has been forced to deploy the J-20 ahead of its schedule since the US has increased the deployment of its fifth-generation stealth fighter jets like the F-22 and F-35s in the Asia-Pacific region.

The US and its allies, including Japan and South Korea, will have more than 200 F-35s by 2025, which means China also needs a similar number of stealth fighters.

To meet demand, China has been working on the development of a purpose-built thrust engine for its stealth fighter since the early 2000s, but has yet to achieve international quality control standards due to problems that include single-crystal turbine blade technology.

Hong Kong-based military commentator Song Zhongping said aircraft engine development had been a long-standing shortcoming but it would not affect the practical fighting capacity of the J-20, which currently uses Russian engines.

“The J-20 hasn’t used the domestic engines so far because it wants a better one, and it still has time,” Song said.

“Other [Chinese-developed] warplanes like the J-10, J-11 and multipurpose attack helicopters are all modified and advanced types, indicating comprehensive achievements amid China’s military modernisation over the past years.”

Besides the domestically developed aircraft, Beijing is going to display its strategic nuclear missiles, such as the DF-41 intercontinental ballistic missile and the JL-2 submarine-launched ballistic missile, as centrepieces of its National Day military parade, according to a Beijing-based military source.

Xi, who also chairs the powerful Central Military Commission, inspected the country’s biggest military parade at the Zhurihe Combined Tactics Training Base in Inner Mongolia in 2017 to celebrate the 90th anniversary of the PLA, but the source said the weapons displayed in Zhurihe had been developed under the leadership of Xi’s predecessor, Hu Jintao.

“Xi needs to highlight his personal achievements in his era, that’s why this year’s parade has political aims more than military significance,” the source said.

The source also highlighted the significance of the People’s Republic marking its 70th anniversary because the Soviet Union did not survive for that length of time.

“Xi is attempting to tell the outside world that Chinese communist regime has been consolidated under his leadership.”
