There are no secrets in the tightly packed lanes of Dharavi, India’s largest slum. Everyone knows when an alcoholic husband turns violent, when children are scolded, or when a family has its television turned up too loud.

So, news that someone had been hospitalized with the new coronavirus rocketed through the 1 square mile (2.5 square kilometers) that is home to around a million of Mumbai’s poorest residents.

Kanase says the people in Dharavi "do not have the privilege to connect with nature. All around Dharavi, you will see only people and houses." So he built the container garden with the help of a friend, especially for his mother who spends a lot of her inside the house. (Kunal Kanase via AP)

The 31-year-old student and community activist hounded government helplines trying to get authorities to quarantine the neighbor's family. Unable to get through, he tweeted at the Mumbai police, who quickly came to take the man's family to a quarantine center.

When a woman who lives just two houses — less than 10 feet (3 meters) away — from Kanase became sick with COVID-19, he once again tried to notify authorities. He was unsuccessful and no one ever came to test or isolate the six other members of the woman's household.

India's poor — in Dharavi and the rest of India — have born the brunt of the nationwide lockdown, which finally began to ease this week. Many migrant workers fled cities for their native villages in the countryside rather than risk starvation, sometimes walking for hundreds of miles (kilometers).

Born and bred in Dharavi, Kunal Kanase watched authorities ignore everyday disasters, like overflowing sewers and domestic violence. He knew better than to wait for help.

“I used to teach his two children and felt good for the family since they were relatively safer now,” he said from the tiny two-room apartment he shares with his parents and younger brother.

Kanase would watch as health workers scrambled to stem the outbreak, suiting up to disinfect the squalid lanes and flying drones over the shantytown to surveil people’s movements.

Mumbai and elsewhere in Maharashtra state in central India account for the largest share of the country’s more than 210,000 confirmed infections , of which more than 104,000 have recovered. India has recorded about 6,000 deaths.

The rate of infection and the loss of life have been relatively small compared to the United States, United Kingdom and other hard-hit countries. But epidemiologists say India is still weeks away from peak coronavirus transmission.

Dharavi is known to the world as the setting of the 2008 Oscar-winning film “Slumdog Millionaire." Set between busy train tracks and the heavily polluted Mithi River, which separates the slum from Mumbai’s modern skyscrapers, the neighborhood is a maze of tiny alleys, each one full of scores of people, many living in tin shacks. Families or groups of migrant workers often pile into a single room. Hardly anyone has a private bathroom.

Without reliable running water, the most worrying concern is sanitation. The neighborhood was able to avoid another disaster this week when it was spared damage from a cyclone that hit the city.

Kiran Dighavkar, a Mumbai official who is overseeing medical workers and volunteers in Dharavi, said his staff is focused on cleaning the neighborhood's 500 toilet complexes. Each is visited by at least 1,000 people a day.

Kanase and his team at Dharavi Diary, a group of young leaders who work to improve conditions in the slum, have been working to help those affected by the pandemic, handing out bags of rice, flour, cooking oil and sugar — enough to feed a family for two weeks. But they lack the resources to provide for everyone and often must filter out the needy from the neediest.

Each day the slum's poorest — often migrant workers originally from elsewhere in the country — line the main street waiting for food handouts from Dharavi Diary and other volunteers, groups and government agencies.
