The coronavirus pandemic is highlighting inequalities in wealth and health care access around the world -- and in Brazil, the crisis has reached the poverty-stricken and densely-populated favelas.
An estimated 13 million people nationwide live in these neighborhoods, where many residents subsist on minimum wage or less and depend on jobs that have been impacted by the pandemic.
CNN's Nick Paton Walsh visited the favelas of Sao Paulo, the country's most populous city.
"This is the place people don't want to live in, yet poverty means it's packed all the same," he said, walking through narrow streets. "It's in these densely-packed alleyways you can tell the real risk of a high infection rate."
One resident in the favela told CNN she had tested positive despite wearing masks whenever going outside to the market. Without much space to self-isolate, she resorted to sitting on her second-floor terrace.
Some context: On Saturday, Brazil surpassed Russia to become the country with the second-highest number of cases globally, after the United States.
The country has seen its numbers spike in recent weeks; on Friday authorities said they had recorded 20,803 new cases in the past 24 hours.
The nationwide total now stands at 330,890 cases and 21,048 deaths, according to data by Johns Hopkins University.
