Social workers are scrambling to track them down, worried they may be vulnerable to traffickers or end up on the streets if left to fend for themselves.

'They're together now'

Just a few months ago, life looked very different for Devika and her family. Devika was focused on studying for a bachelor of education degree, and teaching children in her spare time.

Her father worked as a pandit -- or Hindu priest -- at a temple, and visited homes to perform rituals. He insisted on going out to work, even as cases soared in the capital. Her mother mostly stayed home, taking care of the children, and sometimes helped out at the temple, too.

Devika tried to isolate the children upstairs, but it was too late. The whole family -- including her 53-year-old father -- developed a fever. Although the children were never screened for Covid-19, Devika's mother later tested positive in hospital.

The children recovered, but their mother's condition deteriorated and getting her proper medical care proved impossible. After visiting three hospitals in one night, Devika eventually found one in a nearby city that would take her mother, although it didn't have oxygen or ventilators.

"We were so helpless. We did whatever we could possibly do. But we failed," she said.

Around the same time, her father was admitted to a Delhi hospital. When her mother died on April 29, Devika didn't have the courage to tell him. He had a phrase he would say a lot to his wife: "Without you, there's no fun in living."

Devika recalled the moment her mother's body was taken to the Delhi hospital where her father was being treated, so he could see her one last time before she was cremated.

"Mom was in the ambulance, Dad came out of the hospital and then he saw. He lowered his eyes, and he didn't say anything," Devika said.

After that, she thinks her father lost the will to live. Just a week later, on May 7, he died of Covid, too.

"We really think he wanted to go with Mom," Devika said.

"My father doted on Mummy. They're together now," she added, crying.

After her parents died, Devika worried the authorities would remove her siblings from her. She called up a government-run child care hotline for advice.

They told her she was the primary guardian -- and it was up to her to decide what to do.

The past few weeks have been a blur. Devika took out loans to pay for her parents' hospital treatment, and now that money is helping to keep the family going. She juggles caring for her siblings with her university workload and her part-time job. The family also gets dry rations from non-government organizations, Prayaas and Childline. Devika hasn't had time yet to process her own grief; she wants to be strong for her siblings.

"So much has happened that the tears don't come," she said.

What's being done to help

Devika told the child hotline that she had lost both her parents -- but that's not always the case.

Organizations are searching for children who may need their help, and are relying on social media, hearsay and calls to Childline, a Ministry of Women and Child Development service which existed before Covid.

For rural children, accessing help can be hard. They have less internet access and fewer safety nets, says Save the Children India chief executive Sudarshan Suchi.

"The ones we don't know of is what worries me more," Suchi said.

They also have to contend with restrictions on movement, incorrect information, and fear of contracting Covid from neighbors who might have otherwise helped.

In one instance, Save the Children staff found out about two children whose father died in hospital and whose mother died at home, both from Covid. Both children were suspected of having Covid, so the neighbors in their slum avoided helping them and the children were unable to use the common bathroom spaces, Suchi said.

"If previously an earthquake or flood came into a small village or colony, everybody came together and found ways to rescue. When Covid comes, the first thought everybody has is keep away," Suchi said. "It's an unknown ghost. People with collective spirit and traditions of community action are partly wary today of these kinds of things."

If things go smoothly, children can be connected with their extended family -- the general principle is that institutional care cannot be the first resort, and that a family environment is better for the child, said Anurag Kundu, the chairperson for Delhi Commission for Protection of Child Rights.

But organizations worry about what happens if vulnerable children fall through the cracks, leaving them at risk of winding up on the streets or being trafficked.

In May, Union Cabinet Minister for Women and Child Development Smriti Z Irani urged people who hear about orphaned children to tell the authorities -- and not to share information about them online, lest they are targeted by traffickers.

"Before the pandemic, under normal circumstances, there were more than 2 million children in distress as such on any day on the streets," Suchi said in May. "If anything in the pandemic it could only go worse, not better."

Even before the second wave, more children were living on the streets, Kundu said -- mostly likely victims of India's months-long lockdown that left the country's millions of daily wage earners without work.

"I have never seen so many children on the streets in my whole life as many as I've seen in the last 12 months," Kundu said. "The socioeconomic aspect of it will be felt in the times to come."

What the future looks like

For now, the focus is on keeping children safe. But India's Covid orphans demonstrate how the devastation of the past year will likely be felt long after the pandemic is over.

Suchi said the first priority was survival.

"These children, being already vulnerable, are going to get into a spiral in this. It's not just a question of their sickness from Covid -- it's about their education, it's about their health, it's about their basic social security fabric has come apart suddenly," Suchi said. After that, there needed to be support for their future.

"You can't rescue a child from midstream and then let them drown towards the end of the stream or somewhere towards the bank."

UNICEF India's representative Yasmin Ali Haque agreed, saying it was important to look at not just the child's physical needs -- adequate shelter, food, education, for example -- but also the psychological impact.

"The child is deprived of the loving care of their parents, of growing up in a family environment," she said. "The psychosocial impact on a child can be long lasting, can be lifelong."

The future of her siblings weighs heavily on Devika.

She hasn't told her youngest siblings that their parents are dead -- for now, they've been told their parents have gone back to their village in the countryside.

When her parents were alive, Devika questioned why they went out as the pandemic raged -- the day her mum developed a fever, Devika had asked her not to go to help at the temple. Devika told them it was more important to be alive and safe than to earn.

"I never understood why," she said. "Now that I am where they were, I finally understand them. I get why they left the house."
