Flavio Falcone, a psychiatrist, hugs a man as Andrea Macera.

In his white doctor's jacket, psychiatrist Flavio Falcone could not get homeless drug addicts to talk.

But costumed as a jester with a bright red nose, he has become an icon in Brazil's "cracolandia," or crackland: a dangerous wasteland of about eight blocks in the historic center of Sao Paulo where addicts twitch and pushers roam.

Falcone's patients know him as The clown, not as a doctor.

He treats a growing number of Brazilians, driven onto the street by the COVID-19 pandemic which has devastated the country's economy. Early government support, a lifeline for many, has also wavered.

Falcone is not your average carnival clown.

 Falcone has become an icon in Brazil's crackland.

Infused with hip-hop street culture, he sports a gold chain and flat brimmed cap and struts the streets followed by a speaker blaring rap.

Working with actress Andrea Macera, Falcone uses the costumes and music to break the ice with the homeless as a first step to getting them the mental health and addiction treatment they need.

During "radio" time organized by Falcone and Macera, homeless people in crackland can request songs and even rap along. Around the public square, addicts huddle together and openly light up slim crack pipes.

His work in the neighborhood since 2012 has earned him a loyal following. One man who received addiction help from Falcone tattooed the word "clown" in Portuguese on his wrist.

With government support receding from crackland, Falcone has tried to fill the void.

In April 2020, one month after the pandemic first hit Brazil, the government closed down a homeless shelter here as part of an effort to clean up the city center to make way for construction. The nearest shelter is about 3 kilometers (1.86 miles) away.

Falcone and Macera helped find housing for about 20 of those displaced and to distribute 200 tents provided by a Brazilian non-government organization. In late 2020, they launched a new program called "Roof, Work and Treatment" to offer support to the homeless, with funding from the local labor prosecutors' office.

The homeless population has surged after 600 reais ($106.16) per month government emergency aid payments to the poor were reduced and eventually ran out at the end of 2020. After a delay in congressional approval, payments are set to resume this month at an even lower rate.

For many, that help is too little, too late. Millions have sunk into poverty since the start of the year.
